Precision Resistors Temperature-stable precision resistors are an alternative to strain gages for bridge completion. They are particularly useful when nonstandard bridge resistances are required, and they are also beneficial when higher power levels must be dissipated within the bridge circuit. Precision resistors are designed to be very insensitive to temperature and, therefore, cannot be used to provide compensation for any thermal output from the active gages in the circuit. Unlike strain gages, precision resistors are usually not attached directly to the test part. Rather, a terminal strip is typically bonded to the part for anchoring the resistor leads. As with strain gages, care must be taken to protect both the leads and solder joints from the test environment, making installation somewhat demanding.   Page 3 of 4
