Fixed Gas Detector-SensAlert ASI

SensAlert ASI is a universal instrument platform for toxic & combustible gas detection and oxygen monitoring. Intrinsically safe or explosion-proof mounting configurations with options for remote and gas sensors, duct mounting and sample draw maximize application versatility.

The sensor head accepts all Plus Series sensors – utilizing infrared, catalytic bead, and electrochemical technologies, which detect a wide variety of combustible gases & vapors, toxic & exotic gases, and oxygen deficiency or enrichment.

Assignable and configurable relays along with communication options provide extensive flexibility.

The SensAlert ASI I.S. sensor head can be remotely mounted up to 100 feet (30 m) from the transmitter providing a useful option to place the transmitter in a personnel accessible location while positioning the sensor closer to the potential hazard. SensAlert ASI is designed to address the challenges users face with traditional gas detectors. The universal instrument platform for all gas and sensor types provides common mounting for each point with vertical or horizontal mounting options and removable plug-type terminal blocks to simplify wiring and commissioning. Moveable calibration allows sensor calibration and alarm setting in a safe location, then mounting the sensor into an intrinsically safe sensor head without the need to declassify the area or remove power from the instrument. Plug-n-play capability automatically uploads operating and diagnostic parameters from the sensor after sensor installation.
