The Crowcon IREX IR pellistor replacement flammable Gas Detector is a sinter-free, infrared Gas Fetector that produces an mV Wheatstone Bridge output. In short, it is used to help measure the small variations in resistance that the sensing elements produce corresponding to a physical change. As is used on conventional pellistor based systems. The Crowcon IREX replaces the old pellistor heads that are installed.
The procedure is easy by simply mounting the IREX on the original junction box and connecting to the original cable. The system enables the use of dual-wavelength Infrared Gas Detector technology without possible heavy costs that can occur when replacing the control system and re-installation.
Features
IREX consumes less than 1W of power – ensures compatability with a wide range of control systems
Independantly tested for reliability and performance in harsh offshore conditions by Micropack Engineering Ltd – demonstrates IREX will operate dependable in any application
3rd party approval to the performance standard EN60079-29-1
Employs sophisticated systems and algorithms – ensures reliable operation at all times
T90 response time of less than 4 seconds – rapid indication of hydrocarbon gas hazards
Optical components are treated with a STAY-CLIR coating – prevents partial obscuration in condensing atmospheres
No adjustments are necessary at the Detectors, zero and span adjustments (if required) are performed at the control panel only – saves significant time and cost
Test can be applied remotely via a tube to the standard weather cover
Sinter-free operation – unlike a pellistor Sensor, there is no risk of a sinter becoming blocked.
