The Honeywell RAEGuard 2 PID is a stationary photoionization detector (PID) that measures a wide range of volatile organic compounds (VOCs). The RAEGuard 2 PID operates from 10 to 28 VDC and provides 4-20 mA analog signal output, three-wire signal output, and RS-485 Modbus digital signal. RAEGuard 2 PID uses an intelligent processing platform and digital sensor technology that supports multiple ranges and resolutions and is able to adapt to the environment. Calibration and maintenance are 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 a local buzzer and LED light status indicator. Additionally, 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 with the explosion-proof enclosure in place and operating parameters set. Some of the key applications for the RAEGuard 2 PID along with the PIDs involved are:
Benzene in refinery analyzer shelters
Ammonia in industry
Vinyl chloride in the production of chemicals
Toluene or ammonia in semiconductor factories
Chlorine dioxide, hydrogen peroxide, ozone in pulp and paper
Solvent and chemical storage
Phenol and DME in pharmaceuticals
Toluene in printing
air quality
Methyl ethyl ketone in spray paint booths
Heat transfer fluids
Acetone, xylene, phenol in medical laboratories, pathology, histology
