The IntelliSAW IRM-48 Reader is a remote monitoring unit that provides temperature, partial
discharge (PD), and humidity sensing for predictive condition-based monitoring of electrical
power critical assets such as switchgear, circuit breakers, and bus ducts. Multiple IRM Readers
can be bussed to a CAM-4 system or existing SCADA system providing immediate data display
and alarming.

The IRM-48 Reader is intended for use in the measurement of Temperature, Humidity, Ambient
Temperature, Partial Discharge and Surface Discharge of Low to Medium Voltage air insulated
Electrical Equipment. Readers connect Air Interfaces through RF cables for wireless
interrogation of SAW temperature sensors and Partial Discharge monitoring, while humidity and
ambient temperature sensors are wired to the readers. Interfacing to the IntelliSAW CAM-4 or
an existing SCADA, DCS, or historian is easily accomplished with industry standard Modbus
RTU (RS485 serial).
WARNING
The Reader is not intended for use in monitoring assets above 40KV
The reader is intended to be installed in Low Voltage compartments of switchgear or in similar
types of assets; a unit can also be installed in a weather proof environmental enclosure. The
unit is intended for use at a maximum altitude of 5km, between -40°C to +70°C and between 10
- 95% non-condensing relative humidity. The reader has been recognized for meeting UL
61010-1 safety requirements for electrical equipment. Please refer to Specifications and
Compliance for complete ratings.
WARNING
The Reader is not intended for installation in asset Medium Voltage or High Voltage
Compartments. Only sensors and antennas are intended for installation in medium
voltage Compartments.
