The Honeywell RAEGuard 2 PID is a fixed photoionization detector (PID) that measures a broad range of volatile organic compounds (VOCs) RAEGuard 2 PID Fixed detector continuously monitor for the threat of Volatile Organic Compounds (VOCs) in hazardous locations. This monitor is easy to configure and maintain in the field thanks to a modular design with easy access to PID lamp and sensor, without the need for tools. The internal diaphragm pump speeds sample flow-throw and the unit delivers highly accurate readings with both digital and analog outputs. Low, high, and fault relays can be configured to trigger alarms or integrate with your process controls for automatic shutdown in response to VOC threats. A magnetic key interface enables the detector to be calibrated and operational parameters adjusted with the explosion-proof enclosure in place.
The RAEGuard 2 PID operates on 10 to 28 VDC and provides an analogue (4-20mA) three-wire signal 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 calibration or 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.
A magnetic key interface enables the detector to be calibrated and operational parameters adjusted with the explosion-proof enclosure in place.
