The Micro-Measurments Model 700B Next Generation Welder

The Micro-Measurements Model 700B Welder is the next generation of the Model 700 Welder, which has been used for decades to install tens of thousands of strain gages worldwide. This experience and customer input and support provide more capability and flexibility while remaining in a smaller, more portable package. 

This new welder combines a high-speed spot welding rate with the enhanced safety and portability features that you have come to expect from Micro-Measurements. It is designed for spot welding the Micro-Measurements line of CEA, LWK, LEA, LZN, and LZE weldable strain gages. In all types of adverse field conditions, the 7rugged 00B performs efficiently and dependably.

The 700B's use of commercially available Lithium-ion batteries, which are easily replaced in the field and can handle 1500 welds (@30 joules) on a single charge, is a significant improvement (equivalent to welding around 30 linear weldable gage). The lightweight unit weighs approximately 8.3 lb. (3.77 kg) and is ideal for field use, overcoming the main limitations of other portable spot welders on the market. The unit also welds small thermocouples and light-gauge metal  

The Model 700B enhances Micro-Measurements' broad portfolio of weldable gages suitable for all types of applications and environments. Encapsulated, sealed, and high-temperature versions of Micro-Measurements' CEA, LWK, LEA, LZN, and LZE product families are included. Weldable sensors can be easily installed in field applications under a wide range of weather conditions because they are spot-welded rather than adhesively bonded." 

The Model 700B's welding energy can be easily adjusted by the user from 10 to 60 Joules, with a weld rate of up to 60 welds per minute, making it one of the fastest tools of its kind. The 700B is simple to clip onto a harness or carry around remote job sites, whether working suspended under a structure or in a manufacturing plant. It is particularly well-suited for working from rope access, aerial lifts, or in a laboratory setting. ​

In-Line Color Measurement in the Molten Polymer

Color measurement is a widely used technology for ensuring the quality of color values during the manufacturing process. Typically, these measurements happen offline. The time it takes between sampling and receiving results from the laboratory can be lengthy. A significant disadvantage is that only one measurement occurs during this period, and the color quality during, before, and after the sampling point is unknown. A complete analysis is possible because inline color measurements are performed directly in the melt, but when color variations occur, immediate intervention is possible.

Inline color measurement will provide product-quality indicators for immediate and automatic adjustment of process parameters. The outcome is to maintain the highest possible product quality without waiting for sample analysis from the plant's laboratory.

Equitech International Corp. has been in business since 1995, supplying fiber-optic spectroscopic instruments for process analysis to pharmaceutical, chemical, and food manufacturers. In 2005 they entered the plastics market and began extending their technology into inline color monitoring and real-time closed-loop process control. They published a helpful Technical Paper titled In-Line Color Measurement in the Molten Polymer. You can download that paper here.

New Bench Top Series of Shaker Systems from Sentek Dynamics

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.

About Induction Heating

What is induction heating?

Induction heating is a fast, efficient, precise, repeatable, non-contact method for heating metals or other electrically-conductive materials . An induction heating system includes an induction power supply which converts line power to an alternating current, delivers it to a workhead and work coil creating an electromagnetic field within the coil. The work piece is placed in the coil where this field induces a current in the work piece, which generates heat in the work piece. The coil, which is water-cooled and cool to the touch, is placed around or adjacent to the work piece. It does not touch the work piece, and the heat is only generated by the induced current flowing in the work piece.

Induction heating is used in processes where temperatures are as low as 100 oC (212 °F) and as high as 3000 °C (5432 °F). It can be used in brief heating processes that are on for less than half a second and in heating processes that are on for months.

Induction heating is used in domestic and commercial cooking, and in many applications such as melting, heat treating, preheating for welding, brazing, soldering, curing, sealing, shrink fitting in industry, and in research and development.

In-Line Turbidity and Haze Measurement

Photo 1: Equitech's Retro-Reflection Probe

Monitoring turbidity and haze of liquids and sheet is an indicator for product quality. Examples include: polymer extrusion, resins and chemical production. Real-time adjustments of the process parameters are therefore possible through immediate "off-specification" detection.

INTRODUCTION 

Turbidity and haze measurement is a well-accepted technology to check the consistency some production processes. Usually these measurements are performed ‘off-line’.  

The delay between sampling and obtaining the results from the laboratory can be time consuming. A significant disadvantage is that only a single measurement is generated in this time period and the concentration during, before and after the sampling point is unknown.  

With the inline turbidity and haze measurements taking place directly in the process, not only is complete documentation possible, but when variations occur, immediate intervention can take place.

INNOVATION 

The Equispec™ In-line Color Spectrophotometer (ICS) is a high performance instrument designed for use in an industrial pro-cess. Its excellent sensitivity and flexibility make it useful for process applications. The ICS and process probes are designed to be used in high-temperature, high-pressure and corrosive environments. It can be used to analyze  liquids and solids. 

The analyzer supports one or two probes with dedicated lamp compensation channels [all fiber-optic double-beam design]. 

Photo 3: Trend charts of EquiColor Software

TURBIDITY AND HAZE MEASUREMENT 

Equitech’s fiber-optic probes allow for easy access into the process. Equitech offers probes for both turbidity and haze measurements.  This includes insertion/immersion probes (see Photo 1). 

The spectrophotometer is integrated in a NEMA4 box with an industrial computer and touch-screen (see photo 4). The appropriate spectral range is 380-780 nm (resolution 1 nm). The NEMA4 box is made from stainless steel. It is designed and equipped specifically for use in the production environment where the ambient conditions can be dusty, vary in temperature, subject to vibration etc. The box also contains a thermoelectric cooling and heating device to eliminate the influences from ambient temperature by keeping the temperature inside the box at a constant level.

Bonding Strain Gages? 5 Steps to Getting Surface Prep Right!

When bonding Micro-Measurements Advanced Sensors Technology strain gage sensors (CEA, C4A, C5K)  you want to ensure an excellent bond. The key element in bonding strain gages is surface preparation.

The video above demonstrates specific procedures and techniques with proven advantages. By precisely following these carefully developed instructions (along with the requisite procedures for gage and adhesive handling), the result will be strong and stable bonds. This video presents a procedure that is simple to learn, easy to perform, and reproducible. Keep in mind, it is very important to pay attention to detail and follow the instructions precisely. The importance of surface preparation for strain gage bonding cannot be understated.

1) Degreasing

Rigorously  degrease the gaging area with a good solvent, such as CSM Degreaser or GC-6 Isopropyl Alcohol. Be aware though that some materials (e.g., titanium and many plastics) react with strong solvents. Make sure your solvents do not contain any contaminants

2) Abrading

Preliminary dry abrading with 220 or 320-grit silicon-carbide paper is generally required if there is any surface scale or oxide. Final abrading is done by using 320-grit silicon-carbide paper on surfaces thoroughly wetted with M-Prep Conditioner A; this is followed by wiping dry with a gauze sponge. Repeat this wet abrading process with 400-grit silicon-carbide paper, then dry by slowly wiping through with a gauze sponge.  Finish with 320 grit on most steels and 400 grit on aluminum alloys.

3) Burnishing of Layout Lines

Using a 4H pencil (on aluminum) or a ballpoint pen (on steel), burnish (do not scribe) whatever alignment marks are needed on the specimen.

4) Conditioning

Repeatedly apply M-Prep Conditioner A and scrub with cotton-tipped applicators until a clean tip is no longer discolored. Remove all residue and Conditioner by again slowly wiping through with a gauze sponge. Never allow any solution to dry on the surface because this invariably leaves a contaminating film and reduces chances of a good bond.

5) Neutralizing

Now apply a liberal amount of M-Prep Neutralizer 5A and scrub with a cotton-tipped applicator. With a single, slow wiping motion of a gauze sponge starting within the clean area and wiping outward in one direction.  Repeat the wiping step with a clean gauze pad, again, start in the clean area, wipe though the gage location moving outward in a single stroke to fully dry this surface. Do not wipe back and forth because this may allow contaminants to be redeposited.

For proper outcomes, the procedures and techniques presented here should be used with qualified installation accessory products from Micro-Measurements, namely:

• CSM Degreaser or GC-6 Isopropyl Alcohol
• Silicon Carbide Paper
• M-Prep Conditioner A
• M-Prep Neutralizer 5A
• GSP-1 Gauze Sponges
• CSP-1 Cotton Applicators
• PCT Gage Installation Tape
