RaeGuard 2 PID Fixed Detector for VOCs

The RaeGuard 2 PID is a fixed photoionization detector (PID) that measures a broad range of volatile organic compounds (VOCs). The RaeGuard 2 PID from Honeywell by Rae Systems operates on 10 to 28 VDC and provides an analog (4-20mA) three-wire single output, and RS-485 Modbus digital signal output. Calibration and maintenance have been greatly simplified as the digital PID module can be easily removed in hazardous locations for calibrations and maintenance.

The RaeGuard 2 PID has a graphic display and LED light status indicator for fault and alarm conditions. In addition, Low, High and Fault relays can be configured to trigger external alarms or process controls. Over 200 correction factors are pre-programmed and allow users to display readings of a specific target gas. A magnetic key interface enables the detector to be calibrated and operational parameters adjusted with the explosion-proof enclosure in place.

Features

  • Class 1, Division 1 (Zone 1) continuous VOC monitoring solution for hazardous locations
  • Three wire 4-20 mA analog output and RS-0485 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
