Product information "JUMO wall resistance thermometer with outdoor sensor Protection class IP65"
JUMO Wall-Mounted Resistance Thermometer with Pt100 in Two-Wire Circuit and Measuring Range -30 to +90 °C incl. External Sensor
JUMO Wall-Mounted Resistance Thermometer with External Sensor Protection Class IP65 Type: 902520/22-573-1003-1/000
This wall-mounted resistance thermometer from JUMO is suitable for HVAC temperature measurements with a robust housing design. Equipped with Pt100 in a two-wire circuit, a measuring range of -30 to +90 °C, and an external sensor, this version is designed for wall-mounted measuring points where the sensor is positioned outside the housing so that the temperature can be measured closer to the actual measuring point. With protection class IP65, this wall-mounted resistance thermometer is particularly suitable for HVAC applications in indoor and protected outdoor areas.
Technical Data
- Version: Wall-mounted resistance thermometer with external sensor
- 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
- external sensor for more direct temperature measurement at the measuring point
- IP65 protection class for increased housing protection requirements
- well suited for wall-mounted measuring points in technically demanding environments
- robust design for indoor and protected outdoor areas
The external sensor is particularly useful when the temperature should not be measured directly around the housing but more precisely at the actual measuring location. This distinguishes the version from models with an internal sensor and makes it especially interesting for applications requiring more direct temperature detection.
With protection class IP65, the housing is well protected against dust and water. This makes the version suitable for environments where more robust protection is required than standard room sensors can provide. Especially in HVAC technology, this can be a clear advantage for wall-mounted installations in technically more demanding areas.
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 particularly suitable for applications where the sensor should be connected directly to a compatible control or evaluation unit.
Typical Applications
- Wall mounting in HVAC applications
- Temperature monitoring in technical indoor areas
- Protected outdoor areas
- Heating, ventilation, and air conditioning systems
