Benefits

● Universal 4-20 mA / 1-5 Vdc input measures virtually any type of process function

● 4-20 mA output allows signal to be carried through to other measuring/control equipment

● Software allows gauge to be utilized for various applications

● Bargraph provides operator with vital information "at a glance"

● Fiber-optic backlighting provides consistent illumination under low-light conditions

● Retrofits into existing gauge cutouts

● Setpoint hysteresis for noisy signals

● Setpoint viewing without disturbing monitoring

Operation

AMOT Model 8576B µGauge is an electronic panel meter suitable for use in hazardous environments. The 8576B displays any single process variable in a digital and analog format. As well as the dual display, the µGauge has 2 user configurable discrete outputs, and an additional 4-20mA output for retransmission of the process pressure to other equipment. The 8576B is designed to retrofit into an existing gauge hole and will accept inputs from any 1-5 Vdc or 4-20 m transmitter. The µGauge is completely configurable from the front panel. The user has the ability to change the following parameters: Setpoints, Calibration, Averaging, Output Modes, Bar Graph, Range, Decimal Point Position, Least Significant Digit, Hysteresis, and Sensor Fail Action.
