Product information "JUMO room and outdoor RTD temperature probes Protection class IP54"
JUMO resistance thermometer for temperature measurements in indoor and outdoor areas with operating temperature range -20 to +80 °C
JUMO room and outdoor resistance thermometer without transmitter with IP54 protection class Type: 902520/11-635-1003-1/000
The resistance thermometer with IP54 protection class is suitable for temperature measurements in indoor and outdoor areas. With Pt100 in two-wire configuration and a measuring range from -20 to +80 °C, this version is designed for HVAC applications with increased protection requirements.
This version is intended for temperature measurements where the device should be better protected against environmental influences than standard room sensors. With a Pt100 in two-wire configuration, an operating range from -20 to +80 °C and IP54 protection class, this resistance thermometer is particularly suitable for HVAC applications where temperatures must be measured reliably indoors or outdoors.
Technical Data

Advantages and technical features of the JUMO resistance thermometer for indoor and outdoor measurements
- suitable for indoor and outdoor areas
- IP54 protection class for better protected installation locations
- suitable for temperatures from -20 to +80 °C
- proven Pt100 for classic temperature measurement tasks
- direct integration without integrated transmitter
- good solution for HVAC applications with changing environmental conditions
- more robust design than standard indoor sensors
The main difference compared to simpler indoor variants is the more robust protection class. IP54 makes this version suitable for installation locations where dust or splash water may be present. This makes it well suited for applications where the sensor is used not only in protected indoor environments but also in more demanding surroundings.
A Pt100 sensor in two-wire configuration is used for temperature measurement. This is a proven solution for many classic measurement tasks in HVAC applications. Since no transmitter is integrated, this variant is especially suitable for applications where the sensor should be connected directly to compatible evaluation or control technology.
Typical Areas of Application
- room temperature measurement in HVAC applications
- outdoor temperature measurement on buildings
- technical indoor and outdoor environments
- heating, ventilation and air conditioning systems
- applications with increased protection requirements against dust and splash water
