Strain gauges series
Select strain gauge

There are many kind of strain gauge with different performance. We should consider many reasons to select and use the best strain gauge.


1. We need to consider the terms of experiment and usage. Such as :

A. use precision, 

B. Environment conditions: Temperature, humidity, atrocious environments, interference, stick area, install condition, specification of material etc.


2. We should consider the parameters of the goods.Such as :

Expansion coefficient, elastic modulus, force or stress distribution etc.

Past Strain Gauge

Step 1

Prepare all instrument and Test the resistance firstly..

Step 2

Marking the 45°angle’s cross stripes by the paste direction. And polish the surface of bonding site by sandpaper..

Step 3

Wipe the bonding site in a single direction (must not reciprocated wiping) with absorbent cotton that dipping in or acetone till the absorbent cotton become white.

The bonding site cannot be polluted again, like touched by hands, etc. After mark the strain gauge bonding position, use the same way to clean the surface.

Step 4.

Paste strain gauge is the key step. Strongly brush adhesive all over the bonding site and fundus site thin and equably with technical brush. Then pick up the strain gauge with forceps, paste it along with the axes and marked lines, cover with Polytetrafluoroethylene sheet, and roll press the strain gauge over the sheet with finger along with the axes direction, press out the protruding adhesive and air bubble, check the bonding situation.

Step 5.

The first solidify step is the key point of the solidify procedures, the adhesive will have crosslinking reaction on condition of heating and pressing. So pressure, temperature and time are the most important parameters that directly affect the adhesive. One of the most important conditions for the good load cell is rationally design pressure equipment

Sept 6.

Paste quality inspection
After heating and curing, to inspect strain gauge paste quality seriously, items of Inspection:
a. Resistance changes after Strain gauge paste;
b. Insulation resistance;
c. whether there is a piece of residuary bubbles inside the chips;
d. Paste position accurate or not;

Packing & Delivery
