Standalone ATEX/IECEx Gas Detector Transmitter
Non-Intrusive Gas Detector Transmitter
TOCSIN 903 gas detector transmitter is one of the most versatile standalone ATEX transmitters available on the market. The detector features our non-intrusive calibration method using our magnetic “wand” to perform one-man calibrations while in an ATEX zoned area, no need for expensive complicated ATEX rated interfaces. Simple and efficient whilst reducing downtime.
In addition to this our 903 ATEX gas detector transmitter is approved to both ATEX and IECEx standards for zone 1 and 2 flammable environments and zone 21 and 22 dust environments. When ordered online the sensors are supplied with ATEX rated cable gland and stopping plug.
Versatile Standalone Gas Detector
The TOCSIN 903 gas detector transmitter are incredibly flexible, versatile and easy to deploy. Using both analogue signals and relay outputs, allowing simple integration into any third-party controller, site BMS, control cabinets, fire systems and other gas detection systems.
Detectors utilise our industry leading long-life sensor technology. With sensor options for a wide variety of gases including toxic gases, 5-year Oxygen and Ammonia sensors, leading PID technology, 5-year IR sensors and our patented, long life poison resistant Pellistor sensors for flammable gases. When you install an IGD ATEX 903 gas detector transmitter you are maximising safety and minimising on-going costs using IGD’s extended sensor life.
