CSA Certified
This Particulate Monitoring system is certified by the Canadian Standards Association (to
US and Canadian Standards) for use in hazardous locations as specified below:
Particulate Sensor:
Intrinsically Safe for Hazardous Locations
PMS-AHZ1 Intrinsically Safe Particulate Sensor in the following areas:
Class I, Division 1, Groups A, B, C, and D
Class II, Division 1, Groups E, F, G
Class III
For use with the Control Units listed below, 70ºC maximum ambient.
Note: There is no temperature rise caused by electrical components. Temperature
code is based only on ambient temperature, (e.g. a 200°C process requires a T3
rating.)
Control Unit:
For use in Ordinary Locations Only
DPM-AHZ1 Control Unit rated 115 Vac/230 Vac, 0.1A or 24Vdc, 0.25A, -25ºC to
70°C, with intrinsically-safe output to Particulate Sensor.
DPM-AHZ1 Control Unit - Approved for use with PMS-AHZ1
sensors, where the PMS-AHZ1 sensor is the only component located in
the hazardous area.
