Description
Series 8161 Signal Conditioner/Amplifier is designed for use with strain gage transducers that
can operate with a DC excitation-amplification source. The 8161 series supplies either a 5 volt
or a 10 volt transducer excitation, which can be selected through an internal jumper (see Figure
1). The 8161 series contains all necessary balancing, gain, and calibration controls and
conditions/amplifies the applied input to a standard +/-5 or +/- 10 volt (jumper selectable, see
Figure 1), and 4-20 mA analog output. Calibration of the instrument to the transducer is made
through conventional a shunt technique using an internal calibration resistor. A front panel push
button provides for calibration in the positive direction.

Power connection
The 8161 series is designed to operate on a customer supplied DC power source with a voltage
range of
10
to 28 volts. Screw terminals 1 and 2 are provided for power connections. Reference
Figure 3.

Transducer cabling
High quality twisted pair shielded cable with four conductors is recommended (such as Belden
8723) for transducer hook up. PCB can supply finished cables for transducers with either a
PT02E-10-6P or PC04E-10-6P receptacles if desired. Reference Figure 3 for transducer hook
up.
