IN UVI Wheatstone Bridge In Line Amplifier w Field Selectable IO 12929

 The OMEGA IN-UVI in-line signal conditioner is housed in a rugged stainless steel enclosure, which is connected between the transducer and a readout instrument. The signal conditioner supplies a highly regulated bridge excitation voltage for the transducer and converts the millivolt signal of the transducer to 0 to 5, 0 to 10, ±5, ±10 Vdc or 4 to 20, 12 ± 8 mA.

 
The IN-UVI features include two selectable excitation voltages, programmable gain amplifier for signals from 0.5 mV/V to 4 mV/V, wide zero adjustment range and an isolated shunt calibration relay for quick field setup. All output options and excitation voltages are field selectable.
 
Ready-Made Cable Assemblies are now available to connect the IN-UVI to mV/V output sensors and to the power supply and display (see Specs for details).
