Honeywell Strain Gauge Amplifier

Model U3W Bridge Based Sensor In-Line Amplifier. 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
