Battery-free equipment monitoring

The RFM3240 is built with wireless Smart Passive Sensing™ technology that forms a battery-free and maintenance-free temperature sensor.  This rugged sensor monitors electric distribution and switching equipment temperatures.  Applications include utility-grade electric power distribution, factory and industrial electric service switchgear and other applications where metal surfaces are common.

Wireless temperature sensing

The RFM3240 has a normal operating temperature range of -40°C to +85 °C.  This covers the typical operating temperatures of most equipment over a range of environmental operating conditions.  The RFM3240 reports temperatures beyond its normal operating range to as high as +125 °C, although prolonged operation at such an elevated temperature is not recommended.

Rugged design for use on-metal

The RFM3240 incorporates a rugged antenna design for harsh environments subject to temperature extremes. the RFM3240 is designed for use on-metal surfaces, including electrical distribution busbars.  The integrated RF antenna harvests energy for the temperature sensing function, as well as communicates with a RAIN/UHF compliant reader. The integrated antenna is suitable for use on metal surfaces.

Compatibility

The RFM3240 is available in FCC and ETSI/EU frequency ranges.  The RFM3240 requires a RAIN/UHF compliant reader.  These sensors can be purchased separately or as part of a system.
