Wall-Mounted Resistance Thermometer with Pt100 without Transmitter and Measuring Range -30 to +90 °C

JUMO Wall-Mounted Resistance Thermometer with Remote Protection Tube and Protection Class IP65, Type: 902520/23-573-1003-1/000

The wall-mounted resistance thermometer is suitable for HVAC temperature measurements with a spatially separated measuring point. Equipped with Pt100 in a two-wire circuit and a measuring range of -30 to +90 °C, this version is particularly suitable for measurements where the temperature should not be recorded directly inside the housing but closer to the actual measuring point via a remote protection tube.

Technical Data

  • Version: Wall-mounted resistance thermometer with remote protection tube
  • Measuring insert: 1 x Pt100
  • Circuit type: Two-wire circuit
  • Transmitter: without
  • Operating temperature: -30 to +90 °C
  • Protection class: IP65

Advantages and Technical Features of this Wall-Mounted Resistance Thermometer

  • remote protection tube for more targeted temperature measurement
  • IP65 protection class for increased housing protection requirements
  • well suited for wall-mounted measuring points with a spatially separated measuring location
  • robust design for indoor and protected outdoor areas

The remote protection tube is the key distinguishing feature of this version. It allows the temperature to be measured more precisely at the desired location while the housing remains mounted separately on the wall. This is especially practical when the measuring point is not located directly at the housing installation position or when some structural distance is required.

With protection class IP65, the housing is well protected against dust and water. This makes the version suitable for environments requiring more robust protection than standard room sensors. Especially in HVAC applications, this is an advantage for wall-mounted installations in technically demanding environments.

Temperature measurement is performed using a Pt100 sensor in a two-wire circuit. This proven sensor configuration is suitable for many standard measuring tasks in temperature measurement technology. Since no transmitter is integrated, this version is especially suitable for applications where the sensor should be connected directly to a compatible control or evaluation unit.

Typical Applications

  • Wall-mounted measuring points in HVAC applications
  • Temperature monitoring with a slightly remote measuring point
  • Heating, ventilation, and air conditioning systems
  • Technical indoor areas
  • Protected outdoor areas
