Accurate, Dependable Continuous Monitoring for Electrostatic Charge Build-Up Detection

Advanced Energy’s Monroe 177A offers accurate and dependable continuous monitoring of the critical points in a facility to detect electrostatic charge build-up.

Four-channel static monitor detects static levels in one to four locations up to 1000 feet away
Monitor Console Temperature Range: 15 to 45°C (59 to 113°F)
User Selectable Analog Outputs: ±10 V, 0 to 5 V (2.5 V, ±2.5 V full scale) or optional 4 to 20 mA

Overview

The MonroeTM 177A serves as a full-time, plant-wide automatic static build-up monitor. As static levels surpass a preset value, beyond which there may be a danger to personnel or possible disruption or destruction to the process or product, an initial warning is triggered and the process is allowed to continue. If the problem is rectified, the warning returns to a normal state. If the condition persists and the static level exceeds a second more crucial value, an alarm is activated and terminates the process until corrective action is taken and the system is reset.

Benefits

Detect static levels in as many as four locations up to 1000 feet away
Configure built-in dual level alarms programmable via front panel, PC, or PLC
Cascade up to 32 units via RS485 providing 128 sensor locations
Use the simple GUI interface for set-up and control Increase dependability with password security

Features

Intrinsically safe sensor operation (with optional barriers) in explosive atmospheres
Accurate and drift-free measurement including ionized environments
Provides analog outputs and control via RS232/485 and front panel PLC compatible using
