The feed screw is used in plastics extrusion to force melting plastic resin through a die into a mold to form a desired shape. As screw designs have evolved through the years, there are several generic categories.
Glycon Corporation, the industry leader manufacturer of high performance and innovative feed screws, has put together this white paper describing the classifications of feed screws used in the plastics industry.
The Cox EC80 Flow Processor is a programmable electronic processor, providing total compensation to enhance flow meter accuracy, while extending the linear flow range. Packaging is provided for remote, direct or embedded mounting to support most installation or application requirements.
The compact design includes both single and dual frequency inputs from 4 or 10 ohm pickups, as well an RTD input and an additional analog input for other temperature inputs. The EC80 processor tracks all variables to compensate for viscous and inertial effects, using proven Strouhal-Roshko algorithms. Enhanced DSP technology allows for exceptional signal characterization using a 32-bit floating point processor at 150 MHz, capable of producing a 100 microsecond speed of response.
When bonding Micro-MeasurementsAdvanced 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

The SV 200A is a Class 1 sound level meter integrated with a wireless communication via 3G, LAN, Wireless LAN and Bluetooth®. The list of add-ons also includes a built-in electrostatic actuator, GPS module and e-compass. The waterproof power supply is also provided.
The SVANTEK SV 200A is the top-of-the range noise monitoring station with built-in microphones for noise directivity detection. This innovative, new product enables the identification of dominant noise sources providing information about their location both vertically and horizontally. In practice, measuring directionality gives the opportunity to indicate the dominant source of noise in the measurement area or exclude unwanted events.
Four additional microphones located on the sides of the housing use the sound intensity technique to recognize both the vertical and the horizontal direction of a dominant noise source. Leq distribution in angle sectors is saved as time-history and can be used to filter and report data.
The SVANTEK SV 200A can perform a 1/1 and 1/3 octave frequency analysis in real-time and store it as time-history data. It can also record the audio signal for the recognition of noise sources and recalculation of the data.
The advanced alarm function can send email and SMS notifications caused by threshold levels and time events. Status alarms of the SVANTEK SV 200A are also available.
The 3G modem, Wi-Fi and LAN features provide fast Internet transfer to PC with standard internet connectivity. SvanNET enables Internet plug & play and easy management of measurement projects. Irrespective of the type of a public or private sim card, SvanNET will make a connection to allow full access to your data via Web browser. The Bluetooth ® and Wireless LAN features provide a point of access for easy SvanNET application configuration.
The SVAN 977A is a class-one sound and vibration level meter that offers unprecedented state-of-the-art technology designed for general acoustic, occupational health, and building acoustic measurements of vibration and environmental noise. The instrument comes equipped as standard with the SV7052E polarized half inch microphone, the SV12 microphone preamplifier, and the SA22 foam windscreen, as well as a large 16 gigabyte internal memory which can be easily upgraded by a micro SD card. The meter comes equipped with a standard quarter inch photographic thread. On the bottom panel you can locate the usb serial and I/O sockets. There is also a micro SD card slot under the bottom cover and spaces for the four double a batteries. The SVAN 977A is equipped with a super contrast led color display. The instrument's user interface makes both configuration and measurement easier than ever before. The user can easily operate the instrument by selecting the appropriate position from the selected menu lists.
The instrument has 2 general modes of operation: Configuration mode; and measurement performance and results preview mode. The SVAN 977A can be used in the meter mode to perform the real-time 11 octave or 1/3 octave analysis including calculations of statistical levels, and can also perform FFT analysis. For building acoustic applications SVAN 977A offers reverberation time measurements RT60 and building acoustics assistant application for smartphones.
With a special microphone the meter provides measurement range of the ultrasounds up to 40 kilohertz. Measurement results can be viewed indifferent view modes, the set of which you can change and activate depending on the selected measurement function. If you disconnect the microphone preamplifier, you can use the instrument to take vibration measurements simply by connecting a cable and a vibration sensor. SVAN 977A can be easily installed into the SM277 case and used as an outdoor monitoring station thanks to a dedicated modem station which enables connection to the SVAN NET, an advanced server solution supporting remote connection giving users full access to the measurement data via web browser or dedicated application.
