- In-line Amplifier
- Compatible with Most full bridge strain gauge transducers
- Provides variable excitation and signal amplification
- Accepts both uni-polar or bi-polar input signals
- Simple controls for gain and zero adjustment
- Voltage / 4-20mA output
- IP 65 Rating
- Aluminum Housing
This unit accepts both uni-polar (eg 0 to 4mV) or bi-polar (eg ± 4mV) input signals and can produce corresponding uni-polar or bi-polar voltage outputs (ie 0 to 10v or ±10v) sensitivities and gains given in this document refer to both. Current outputs (4 to 20mA) are uni-polar.
Excitation, coarse gain, fine gain and fine zero controls are provided, with the facility to connect remotely an internal shunt calibration resistor. Connections are made via screw-terminals which, with the controls, are all mounted inside an aluminium case, sealed to IP65 specification.
Note that the voltage output common (0v terminal) with a single (2 wire) supply voltage, is approximately at the mid supply voltage eg with a 24 volt supply the output common is 12 volts.
