A fixed photoionization detector (PID), the RAEGuard 2 PID measures a wide range of volatile organic compounds (VOCs). The RAEGuard 2 PID provides an analog (4-20mA) three-wire signal output, RS-485 Modbus digital signal output and operates on 10 to 28 VDC. The maintenance and calibration of the RAEGuard 2 PID has been greatly simplified as the digital PID module can be simply removed in hazardous locations for maintenance or calibration.

There is a graphic display and LED light status indicator for the RAEGuard 2 PID. The LED light status indicator for fault and alarm conditions. Additionally, Low, High and Fault relays can be configured to set off process controls or external alarms. There have been over 200 correction factors pre-programmed and allow users to display readings of a specific target gas. The RAEGuard 2 PID detector's magnetic key interface enables the detector to be calibrated and operational parameters adjusted with the explosion-proof enclosure in place.

Key Features

  Class I, Division 1 (Zone 1) continuous VOC monitoring solution for hazardous locations
  Three wire 4-20mA analog 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.
