Choose Druck for Supply Chain Confidence

Choose Druck for Supply Chain Confidence

Since the pandemic, supply chain disruptions have posed a significant threat to the global economy. Factory closures and lockdowns in China and several other nations, labor shortages, strong demand for commodities, logistics network disruptions, and capacity limits have resulted in significant delivery times. Manufacturers have had to make tough choices, even relinquishing agency approvals on whole product lines.

Druck maintains regular lead times on pressure instruments and has shortened lead times from 4 weeks down to 3 to meet manufacturers' demands, particularly those facing supply chain disruptions. 

According to a poll done by the National Association of Manufacturers, 36% of companies suffer supply chain disruptions, with items arriving late or not at all. Druck works closely with its supply chain to maintain a 3-4 week delivery on the UNIK 5000 series. 

As firms look for alternative suppliers, Druck demonstrates their dependability as a domestic pressure instrument supplier, serving critical industries.

Sensuron - Distributed Measurement Using Fiber Optic Sensing

Distributed Measurement Using Fiber Optic Sensing

Sensuron provides intrinsic fiber optic sensing technology, using the fiber optic cable as the sensor. There are three generations of intrinsic fiber optic sensors: point fiber bragg grating (FBG) based sensors, scattering based sensors, and spatially continuous FBG based sensors. Scattering techniques use fully distributed measurements, whereas FBG techniques can use a small number of sensing points or be fully distributed, depending on how the system interprets the signal from the sensing element. 

FBGs, manufactured into the fiber's core, act like tiny mirrors. Each grating reflects a portion of the signal to the system as light travels down the fiber. The system detects and interprets changes in the returning signal to provide accurate strain and temperature measurements. The majority of FBG-based systems have a few sensing points along each fiber. While this multiplexing capability improves legacy technology, it still does not provide the sensor density required for monitoring continuous distributions. Precision, dynamic testing, and high-speed data acquisition are advantages of point FBG sensors. 

Scattering techniques do not use FBGs at all instead of relying on flaws in the fiber optic cable to obtain readings. There are three types of scattering technologies used in sensing systems today, each with its own set of capabilities. In general, distributed data and long sensing lengths benefit scattering-based fiber optic sensing systems. They are, however, limited to static operation due to low data fidelity, prolonged data acquisition rates on the order of minutes, and susceptibility to vibration. 

Sensuron employs a method that combines the advantages of point FBG sensors and scattering-based systems. Sensuron uses FBGs as the sensing element in their fiber but inscribes them continuously along its length. This process, including the signal interpretation technique, enables their platforms to collect spatially continuous data while maintaining the precision, dynamic testing, and high acquisition rates provided by FBGs. Engineers benefit from accurate measurements of full strain fields, temperature gradients, and other parameters in both static and dynamic environments. Sensuron's platforms can also measure internal and applied loads, deflection, 3D shape, and liquid level using the distributed strain data provided by the fiber.

This technology breakthrough in design architecture, which includes an all-new innovative feature set, provides more versatility than any other induction heating system available today — all while delivering exceptional product performance.

Auto-Scan Capability
While an Ambrell Applications Laboratory will test your application and determine the necessary frequency, you may decide to take on additional applications later. If so, Auto-Scan will scan your application, auto-set the starting frequency and recommend RF setup parameters. If your application is outside of your EKOHEAT VPA model’s capabilities it will even offer recommendations.

High Resolution RF Output
The EKOHEAT VPA displayed RF output is the power actually delivered to the workhead. Resolution is better than 0.05% of full scale.

Universal Printed Circuit Boards
Regardless of system size and frequency, all EKOHEAT VPA products use common printed circuit boards (PCBs). A single board set addresses multiple EKOHEAT VPA systems, minimizing your inventory and eliminating model specific versions.

Industrial Ethernet Communication Compatibility
Industrial and Automation environment networking is fully supported using our chosen gateway that include CIPs (Common Industrial Protocols) such as EthernetIP, Modbus/TCP, and PROFINET protocols.

Easy-to-Use Touch Panel
The front touch panel display will allow you to easily adjust key operating parameters, change languages and read system diagnostics.

Soft Start Circuitry
AC power will not be disrupted when switching on the power to your EKOHEAT VPA power supply thanks to this feature. It eliminates the risk of tripping up other equipment when a power supply is turned on.

Universal Application Setup
The EKOHEAT VPA RF transformer accommodates worldwide voltages and provides the same output voltage. An application conducted in Europe uses the same application setup in the United States.

Two Remote Inputs
Added versatility is provided using a second remote input. Additional process variables, such as temperature can be measured, displayed, recorded and played back with the associated generator parameters.

Application Record and Playback
This feature enables you to record your heat cycle – for up to five weeks – and play it back. The benefit is that you can optimize your application and run it in the most efficient manner.

Ability to Add Power
All EKOHEAT VPA systems have the ability to work together. If you install a 250 kW system and realize later that you need 375 kW, just add a 125 kW system and they will work together seamlessly to deliver 375 KW.

RoHs Compliant
EKOHEAT VPA systems are RoHs compliant, meaning they are free of hazardous materials.

Cost Effective, Speedy Force Calibration System from BLH Nobel


A BLH Nobel customer's manufacturing process included multiple critical tanks that required regular weight calibration. The largest, a reactor, weighs 60 tons. Traditionally, they calibrated the vessels by filling them with water, a laborious and expensive process. It took a week for each tank.  Aside from filling the tanks, each must be emptied and rinsed. Finally, calibration required thorough drying before resuming production. 

BLH Nobel developed a method to elevate the vessels and read the weight change at various stages of the process. This video demonstrates that method.

BLH Nobel's solution allows the calibration of a weighing vessel, silo, or tank in a fraction of the time compared to using flowmeter or weighbridge calibration. BLH Nobel jacks the tank using hydraulics instead of loading with weights or flowmeter. Typically they measure the result in several points and verify the weighing result. BLH Nobel's method is often carried out without modifying the existing frame or structure, as most already have a suitable jacking point at each load cell.

For more information about this weighing calibration process or any BLH Nobel products in New England, contact AP Corp. Call (508) 351-6200 or visit https://a-pcorp.com.

Combat the Hazards of Plastics Screw and Barrel Wear

Combat the Hazards of Plastics Screw and Barrel Wear

This post is abstracted from an excellent article from Plastics Technology Online
written by Jim Callari. Read the full text here.

Industrial-grade screw and barrel wear cuts throughput speeds, producing scrap before shutting down. For the first time, technology is making progress in unraveling the mystery of screw and barrel wear. 

There has been a lot of injection molding machine innovation in the past year. And now, Glycon Corp. has the technology to test wear within the plasticating device. Glycon is in the first phase of rolling this technology out in the industry. It will concentrate on extrusion and blow molding. 

With this capability, they have developed the technology to calculate the rate of wear and predict future wear. This data determines the most cost-effective time to replace these components.

Glycon has been working on measuring wear since 1986 gained their first patent as Great Lakes Feedscrews. The company expanded the invention to include measuring barrel wear and was awarded additional patents in 2006, 2007, 2008, and 2019. 

Wear and tear challenges are well documented over the years, and plastic processors know the symptoms. Many machine operators compensate by making changes to the screw speed or temperature settings. The problem is, both of these changes would ultimately result in lower efficiency and higher scrap rates. 

The new system called EMT (short for Electronic Measurement and Tracking), includes Glycon's flite-scan eddy-current sensors mounted in one or more positions within a SmartBarrel. These barrels also have SmartPorts, another innovative technology offered by Glycon. 

Measurements will be conducted routinely at the processor's plant by field technicians using a Flite-Scan sensor. Several eddy-current sensors were tried over the years. Multiple sensor manufacturers were collaborated with, but all ran into failure at high temperatures in the plasticating units. 

Micro-Epsilon, a leading manufacturer of sensors that measure displacement, distance, position, vibration, dimension and thickness, was the eventual choice because their sensors proved much more robust and provided reliable readings up to 600 F. 

The EMT system is not only to analyze the data to determine the optimum time to replace or repair worn screws or barrels to optimize productivity but also to relate the wear to:

  • Materials of screw/barrel construction.
  • Screw/barrel alignment. 
  • Polymers being processed.
  • Impact of abrasive fillers.
  • Performance related to wear, including production rates, cycle times, energy consumption, melting rates, head pressures and melt temperatures.

The Glycon EMT system's advantages are that it provides precise measurement of the wear on the OD of the feedscrew and the barrel's ID and its simplicity and cost-effectiveness. It allows maintenance personnel to plan to measure intervals and to schedule changeouts at convenient times based upon wear-rate data rather than 'running to failure' and having to run inefficiently or not at all.

Distance Measurement for Reflecting Surfaces with Universal Laser Sensor

Distance Measurement for Reflecting Surfaces

Plastics, mirrored glass, or metals have highly reflective surfaces and require special laser sensors to measure displacement and distance. Displacement and distance measurements on strongly reflecting surfaces challenge conventional, diffuse reflection laser sensors. 

Laser sensors such as the Micro-Epsilon optoNCDT 1750DR provide a real-time surface compensation feature that controls exposure time that produces stable signals. This type of laser sensor operates on the principle of direct reflection, aligned so that the angle of incidence is equal to the angle of reflection. Proprietary algorithms compensate for the back-scattered, high-intensity light—all of this in a compact design, including an integrated controller (no external control unit is required).

Mounting and wiring are easy. A mounting template enables the user to align the sensor correctly. The laser class 1 rating on which the optoNCDT 1750DR operates is another advantage. Additional safety precautions are not necessary since the emitted laser power does not exceed 390 µW. Users have the choice of an intuitive web interface which can operate the laser sensor from a browser.

Which Melt Pressure Sensor Is Good for My Application?

Melt Pressure Sensor Selection

So how do I choose the right melt pressure sensor for my application? 

A sensor is defined through the following specifications:

  • Pressure Range
  • Process connection
  • Electrical output and connection
  • Capillary configuration (rigid/flexible)
Melt Pressure Sensor

There are more variables come into play, but let's focus on these four since they are the most critical.

Melt Pressure Sensor Pressure Range


The pressure inside a plastics processing machine can usually be estimated well enough to determine a sensor's good pressure range. The typical working pressure should be within 20%-80% of the sensor's pressure range to balance accuracy and lifetime.

Melt Pressure Sensor Process Connection


For threaded connections in plastics processing, a standard has developed over time, which is the ½"-20UNF thread with a conical sealing face. There might be situations where different thread sizes or a flange connection is required. There are numerous options available from manufacturers, such as Dynisco, to satisfy customer needs regarding the process connection.

Melt Pressure Sensor Electrical Output


Melt Pressure Sensor Electrical Output

A pressure sensor is an electro-mechanical device that converts a mechanical effect (pressure deflects a thin piece of metal) into an electrical signal through a strain gauge. The strain gauge changes its resistance by following the deflection of the metal piece. In the simplest case, the strain gauge signal can be used directly to feed a read-out device to display the pressure.  In order to accommodate industry-standard equipment, such as process control equipment, manufacturers like Dynisco supplies sensors with different amplified output options such as 4-20mA or 0-10V.

Melt Pressure Sensor Capillary Configuration

Melt Pressure Sensor Capillary

A typical pressure sensor has a liquid-filled capillary that connects the process-connection diaphragm (which is deflected by the process pressure) and the measuring diaphragm (where the strain gauge is bonded). This capillary is necessary to create a heat barrier, as the strain gauge cannot withstand the typical process temperatures at plastics processing. Also, the sensor's electronics need to be kept away from heat sources as well as possible. To find a suitable mounting location for the electronics, countless combinations of the rigid stem and flexible connection lengths are available.

Other Considerations in choosing a Melt Pressure Sensor:

  • Diaphragm materials
  • Diaphragm coatings
  • Approvals and certifications

New Bench Top Series of Shaker Systems from Sentek Dynamics

Bench Top Series of Shaker Systems

The BT Series shakers from Sentek Dynamics are designed for demanding vibration test applications. Typical applications included structural analysis, calibration and testing of smaller assemblies. The BT-100 through BT-400 shakers utilize light weight rare earth magnets in lieu of traditional Alnico magnets. The use of these magnets decreases the total shaker mass to a third of similar size system, making these shakers easy to handle and portable. 

The systems range in size from 100 N (70 lbf) to 1000 N (224 lbf). Systems 400 N (99 lbf) and smaller are permanent magnet shakers and use lightweight rare earth magnets, making these systems easy to handle and portable. There are three versions of the BT Series of shakers: the BT, BT-M and BT-MTH.  

The BT Series is recommended for vibration testing of small assemblies and components. These shakers have armature diameters from 60 mm (2.36 in.) to 120 mm (4.72 in.). The BT-1000 is equipped as standard with Automatic Armature Centering (AAC) and Air-Isolation Feet (AIF).  

The BT-M and BT-MTH Series are our modal shakers lines. BT-M will use standard stingers while the BT-MTH is our through-hole version. On the 100 N and 200 N system the BT-MTH offers over double the displacement. The BT-MTH Series allow you to use piano-wire stingers. The BT-1000-M is ideal for the structural and modal analysis of high-mass structures. The addition of ZPR (electronic zero-point regulation and adjustable suspension stiffness) allows the user to pre-load the structure prior to applying a dynamic load.

The new Sentek Dynamics Bench Top and modal exciters are based upon years of practical experience. These systems all exhibit a high lateral stiffness and high force-to-weight ratio. They are specifically designed to help ensure the best possible performance with minimum setup time.
