Product Name
Limit Switch Box, Valve Monitor
Model No.
ALS400M2F
Overview
The ALS400M2F Limit Switch Box (Valve Position Transmitter Monitor) is a rotary position indication device suited for HAZARDOUS area (Exd II CT6). Armed with mechanical switch and position transmitter, this device can sense mechanical position (on/off) as well as the position change (0°~90°) of valve and output 4~20mA for remote PLC or PC indication. The visual indicator on the top of the device can also clearly display the valve position for local detection.
