The Model U3W amplifier has been designed to supply a highly regulated bridge excitation voltage for the transducer and converts the millivolt signal of the transducer to a 4 mA to 20 mA three-wire current output signal.
Features:
Strain gage sensor amplifier
18 V dc to 32 V dc supply voltage
NEMA 4 housing
Selectable excitation voltages: 3 V or 5 V at 70 mA
4-20 mA analogue output
Increases signal-to-noise ratio in noisy environments
Effects of voltage drops in excitation sources are eliminated
Signals may be sent to the data systems from low impedance sources
