MNU IS Intrinsically Safe Modbus Ultrasonic Level Sensor 05954

MNU IS ultrasonic sensors are rugged units, rated Intrinsically Safe for hazardous location installations. They feature
APG’s new QuickMode for power-saving, on-demand measurements, and optional GDT surge protection. All MNU
IS sensors are fully programmable via RS-485 Modbus communications, and with APG Modbus software and an RS485-to-USB converter.

New QuickMode
Get an on-demand measurement in as little as 250 ms.

Easy Wiring & Set-up
Everything about MNU IS setup is easy, from simple daisy chain wiring to remote configuration via the Internet.
