8575 - µGauge

Features

● Reads any process pressure variable

● Dual switch outputs n4-20 mA auxiliary output signal

● Includes 17-4 PH stainless steel remote mount transducer

● Two protected adjustable set points - independently configured as rising or falling

● 4 1 / 2 digit display

● 101 segment bar graph with setpoint indication - linear or differential

● Menu driven software configuration (no external programming device required)

● Unique display shows both analog and digital values simultaneously; shows setpoint position and condition

Benefits

● Remote mount strain gauge transducer prevents process fluid from entering panel

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

● User configurable software allows gauge to be utilized for various applications

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

● Retrofits into existing gauge cutouts

Operation

AMOT Model 8575B µGauge is an electronic panel meter suitable for use in hazardous environments. The 8575B displays any single process pressure 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 8575B is designed to retrofit into an existing gauge hole and comes complete with an approved transmitter (AMOT Model 8580). The µGauge is completely configurable from the front panel. The user has ability to set the following parameters: Setpoints, Calibration, Averaging, Output Modes, Bar Graph, Range, Decimal Point Position, Least Significant Digit, Hysteresis, and Sensor Fail Action.
