060-6827-03
Model U3W Universal Inline Amplifier with 4 mA to 20 mA Output and 18 Vdc to 32 Vdc Input
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 excitation voltages, programmable gain settings, a wide adjustment range on the zero, and a buffered solid-state shunt cal relay for quick calibration.
