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.

Step 3.

Polish the surface of bonding site by   sandpaper.

Step 4

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.

Step 5.

Strongly brush adhesive all over the bonding site and fundus site thin and equably with technical brush.

Step 6.

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.

Step 7.

Welding the lead wire. Be careful that the wire is easy to be connected to the elastomer.

Setp 8.

It must solidify according to the specification of adhesive, and can’t stop power during solidify.

Step 9.

Paste quality inspection
a. Resistance changes after Strain gauge paste;  b. Insulation resistance;
c. Paste position accurate or not
