Model U3W Bridge Based Sensor In-Line Amplifier DESCRIPTION The Model U3W amplifier supplies 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. The Universal In-line features two selectable exci- tation voltages, programmable gain settings, a wide adjustment range on the zero, and a buffered solid-state shunt cal relay for quick calibration. FEATURES Strain gage sensor amplifier 18 Vdc to 32 Vdc supply voltage NEMA 4 housing Selectable excitation voltages: 3 V or 5 V 70 mA 4-20 mA analog 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 impe- dence sourcesModel U3W PERFORMANCE SPECIFICATIONS OPTION CODES Many range/option combinations are available in Characteristic Measure 2-pole active our quick-ship and fast-track manufacture pro- ltfi er Number of channels 1 grams.
