If a strain gage transducer is connected to a signal conditioner, digital indicator or strain amplifier via extension cable, we cannot ignore the sensitivity decrease due to the extension cable resistance which lowers the voltage applied to the transducer.

The rated output with lowered sensitivity can be obtained by the following equation:

Bridge resistance R = 350��, Reciprocating resistance per 1 m of four 0.5mm 2 -conductor chloroprene cabtyre extension cable = 0.0794�� (approx. 0.08��)
