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

New Product Alert: A Noise Monitoring Station with Built-in Noise Directivity Detection


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.

Why Plastics Industry Feed Screws are Designed the Way They Are

Feed screw selection
Download the white paper here.

The selection of the proper screw for a given injection molding or extrusion application can be critical to its success.

Screw geometry — length-to-diameter ratio, profile, channel depth, compression ratio, helix angle and a host of special design features — has everything to do with how well the screw performs in a given application.

There are documented applications where customers have improved production rates or reduced cycle times by 30 or 40% simply by switching to an improved screw design. Similarly, reject rates have been lowered from more than 4-6% to less than 1% by incorporating a custom designed mixing screw.

And experience shows that the amount of color concentrate required to achieve optimum color mix can be typically reduced from 4% (of the total blend) to 2%, just by using an optimized screw design. When considering resin and concentrate costs, payback for an optimized screw and non-return valve design can be almost immediate.

This white paper, published by Glycon Corporation, provides an in-depth look into plastics industry feed screw design.
