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 1 can be configured to trigger external alarms or
process controls. Over 200 correction factors 1 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.
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
Applications
- Refineries and petrochemical plants
- Power plants
