JUMO Wall-Mounted Resistance Thermometer with Pt100 in Two-Wire Circuit and Operating Temperature -30 to +90 °C
JUMO Wall-Mounted Resistance Thermometer with Internal Sensor Protection Class IP65 Type: 902520/21-573-1003-1/000
The wall-mounted resistance thermometer is suitable for temperature measurements in HVAC applications with increased protection requirements. Equipped with a Pt100 sensor in a two-wire circuit, a measuring range of -30 to +90 °C, and protection class IP65, this version is designed for compact wall-mounted measuring points in indoor and protected outdoor areas.
This version is intended for wall-mounted temperature measurements and is especially useful where the sensor is protected inside the housing while requiring a robust outer enclosure.
Technical Data
- Version: Wall-mounted resistance thermometer with internal sensor
- Measuring insert: 1 x Pt100
- Circuit type: Two-wire circuit
- Transmitter: without
- Operating temperature: -30 to +90 °C

Advantages and Technical Features of the JUMO Wall-Mounted Resistance Thermometer
- compact wall mounting with integrated internal sensor
- IP65 protection class for increased housing protection requirements
- closed design without protruding sensing element
- Pt100 sensor for proven temperature measurement
- suitable for temperatures from -30 to +90 °C
- direct integration without integrated transmitter
- well suited for HVAC applications with increased protection requirements
The internal sensor makes this version particularly interesting for measuring points where the temperature is to be recorded directly in the area surrounding the housing without requiring a protruding sensing element. This can be advantageous wherever a compact, closed design is preferred and the sensor should remain better protected against mechanical influences.
With protection class IP65, this version provides significantly greater protection against dust and water than standard room sensors. This makes it suitable for environments where the housing is exposed to higher levels of stress or where a higher protection rating is required. Especially in HVAC technology, this can be beneficial for installations in more 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 measurement tasks in temperature measurement technology. Since no transmitter is integrated, this version is particularly well suited for applications where the sensor is connected directly to a suitable control or evaluation unit.
Typical Applications
- Wall mounting in HVAC applications
- Temperature monitoring in technical indoor areas
- Protected outdoor areas
- Applications with increased protection requirements against dust and water
- Heating, ventilation, and air conditioning systems
