RAEGuard 2 PID Fixed Gas Detector
The RAEGuard 2 PID is a fixed photoionisation detector (PID) that measures a broad range of volatile organic compounds (VOCs). The RAEGuard 2 PID operates on 10 to 28 VDC and provides an analog (4-20mA) three-wire signal output, and RS-485 Modbus digital signal output. Calibration and maintenance have been greatly simplified as the digital PID sensor module can be easily removed in hazardous locations without tools for calibration or maintenance.
Key Features:
- Class I, Division 1 (Zone 1) continuous VOC monitoring solution for hazardous locations
- Three wire 4-20mA analogue output and RS-485 digital communication in Modbus protocol
- Three dry contact relays (<30V, 2A) normally open (or normally closed), one for high and low alarm, another for fault alarm
- Explosion-proof stainless-steel enclosure suitable for outdoor hazardous environment applications
- Magnetic-key interface eliminates the need to open the explosion-proof housing when adjusting parameters
- Continuous VOC monitoring in hazardous and non-hazardous area locations
- Reduced maintenance costs due to easily removable sensor module. Sensor and lamp can be removed without tools and serviced in hazardous locations
- Faster response time with sample flow-through design powered by internal diaphragm pump
- Humidity compensation ensures accurate readings even in humid environments
