Battery-free equipment monitoring
The RFM3254 is a wireless battery-free temperature sensor. This rugged sensor is designed to electric distribution switchgear equipment temperatures in the harsh and extreme environments. Typical applications include switchgear contact assemblies, cable heads, busbars, Power distribution Units (PDUs), Ring main Units (RMUs) and other applications where metal surfaces are common.
Wireless temperature sensing
The RFM3254 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 RFM3254 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 RFM3254 is built with a robust composite antenna and is ideal for harsh environments subject to temperature extremes and the elements. 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.
Compatibity
The RFM3254 is available in FCC and EU/ETSI frequency ranges. The RFM3254 requires a RAIN/UHF compliant reader. These sensors can be purchased separately or as part of a system.
