Explosion Proof Transmitter - AST-X
The AST-X series are rugged, reliable analog transmitters available with electrochemical or catalytic sensors to detect a wide range of gases. Explosion-proof housings are used to meet the requirements of many different applications. AST-X transmitters feature 4 to 20 mA or 0 to 10 VDC linear output signals, utomatic thermal resetting fuse and LED indicators for power, sensor status and alarm condition. There is an optional relay board with field adjustable setpoint. Calibration and maintenance procedures are simple and are easily performed in the field. Housings are available with or without window.
