OI-WF190
The Otis Instruments, Inc. WireFree Model OI-WF190 (or OI-WF190-IR) Sensor Assembly is an innovative wireless gas detection system designed to monitor gas in hostile environments without the use of wires or conduit from the controller to the sensor.
The OI-WF190 is a DC powered sensor assembly that measures LEL (or CO2). The sensor functions by transmission of radio wave messages to any Otis receiving controller. The device is field adjustable for background gas and addressable to eliminate interference with other systems.
The OI-WF190's enclosure is Class I, Division 1 certified and can be calibrated non-intrusively by using an Otis Instruments, Inc. distributed magnet.
Features such as the relay/alarm tests and battery voltage indication make this device a truly remarkable gas detection system.
