U3W Model Inline Amplifiers

The Model U3W amplifier supplies a highly regulated bridge excitation voltage for the transducer and converts the millivolt signal of the transducer to a 4mA to 20mA three-wire current output signal. The Universal inline 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.

Product Features:
  • Strain gage sensor amplifier
  • 18Vdc to 32Vdc supply voltage
  • NEMA 4 housing
  • Selectable excitation voltages: 3V or 5V at 70mA
  • 4mA to 20mA 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 impedance sources
