Electrical specification
29
The differential input is connected to a force or pressure
transducer, or to a strain gauge. The 1902 can provide the
voltage excitation needed. For half-bridge types, binding
adaptors must be used to complete the bridge.
Single-ended transducers should be connected between the +ve
input (pin 5) and ground (pin 1). The –ve input (pin 7) should
be linked to ground. The 1902 voltage offset facility on pin 6
can be used to back off a static voltage level at the transducer
output.
