Strain Relief: Installing Gage With Option P

Strain Relief

Before unsecuring the cable bundle, it is recommended that strain relief loops be provided in both the cable and jumper wires. Form these loops over the handle of a dental probe or rod of similar diameter. The jumper-wire loop, which should lie in the plane of the specimen, is usually held in place by the protective coating. The cable loop, which should remain upright, is usually located outside the coated area. M-LINE 3145 RTV silicone rubber can be used as a cable anchor.

After the cable has been properly anchored, the remainder of the bundled cable can be unsecured and routed to the strain gage instrumentation. If a cable extension is added, remember that it should be attached by soldering. Alligator clips, twist caps, and most other mechanical connections should be avoided when making electrical connections within strain gage circuits.

Gages supplied with Option P can be installed readily with these techniques in most applications. Should you have any questions about your particular application, our Applications Engineering staff here at the Vishay Measurements Group are always ready to assist you.
