The Wheatstone bridge IN-UVI in-line signal conditioner is housed in a stainless steel enclosure that is connected between the transducer and a readout instrument. While providing accessibility for transducer field calibrations especially when space is limited, the signal conditioner is suitable for applications in which a transducer must be located in a hostile environment or some distance away from the display. It supplies a regulated bridge excitation voltage for the transducer or load cell. Features include improved signal-to-noise ratio, two selectable excitation voltages, wide zero adjustment range and an isolated shunt calibration relay for quick field setup. All output options and excitation voltages are field-selectable.
