Product information "JUMO wall resistance thermometer with internal sensor Protection class IP65"
Wall-Mounted Resistance Thermometer by JUMO with Pt1000 in Two-Wire Circuit and Operating Temperature -30 to +90 °C
JUMO Wall-Mounted Resistance Thermometer with Internal Sensor Protection Class IP65 Type: 902520/21-573-1005-1/000
This wall-mounted resistance thermometer from JUMO is suitable for HVAC temperature measurements with a compact housing design. Equipped with Pt1000 in a two-wire circuit and a measuring range of -30 to +90 °C, this version is designed for wall-mounted measuring points in indoor and protected outdoor areas.
This version is suitable for wall-mounted measuring points where the sensor should be protected inside the housing while a Pt1000 signal is required. With an operating range of -30 to +90 °C and 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 internal sensor
- Measuring insert: 1 x Pt1000
- Circuit type: Two-wire circuit
- Transmitter: without
- Operating temperature: -30 to +90 °C
- Protection class: IP65
Advantages and Technical Features of this JUMO Thermometer Version
- compact wall mounting with integrated internal sensor
- IP65 protection class for increased housing protection requirements
- closed design without protruding sensing element
- Pt1000 sensor for compatible control and evaluation systems
- 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 especially interesting wherever the temperature should be measured directly around the housing without requiring a separate protruding sensing element. This creates a compact design and is particularly practical where a discreet, closed solution is preferred.
Unlike Pt100 versions, this model operates with 1 x Pt1000 in a two-wire circuit. This is particularly useful when the connected control or evaluation system is designed for Pt1000 or when this sensor configuration is preferred. Since no transmitter is integrated, the device is especially suitable for applications where the sensor should be connected directly to a compatible evaluation unit.
With protection class IP65, the housing is well protected against dust and water. This makes the version suitable for environments where standard room sensors are not sufficient and a more robust housing is required. Especially in HVAC technology, this can be an advantage for wall-mounted installations in technically demanding areas.
Typical Applications
- Wall mounting in HVAC applications
- Temperature monitoring in technical indoor areas
- Protected outdoor areas
- Heating, ventilation, and air conditioning systems
