Wheatstone Bridge In-Line Amplifier W/ Field Selectable I/O

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).
