Battery-free equipment monitoring

The RFM3260 is a wireless battery-free temperature sensor. This lug-mounted sensor is designed to monitor electric distribution and switching equipment temperatures. Typical applications include utility-grade electric power distribution, factory and industrial electric service switchgear, large office building power distribution, data centers, remotely distributed ring-main-unit (RMU) attachments to the primary electric grid, and other applications where metal surfaces are common.

Wireless temperature sensing

The RFM3260 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 RFM3260 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 RFM3260 incorporates a unique antenna design for harsh environments subject to temperature extremes. 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 that might otherwise adversely affect wireless/RF communication range.


The RFM3260 is available in FCC and EU/ETSI frequency ranges. The RFM3260 requires a RAIN/UHF compliant reader. These sensors can be purchased separately or as part of a system.
