Product information "JUMO room resistance thermometers Protection class IP20"
JUMO room resistance thermometer for temperature measurement in indoor areas and HVAC applications for measuring range -30 to +80 °C
JUMO room resistance thermometer with Pt100 in three-wire configuration and IP20 protection class Type: 902520/10-572-1001-1/00
The room resistance thermometer with IP20 protection class is designed for temperature measurement in indoor areas and HVAC applications. With Pt100 in three-wire configuration and a measuring range from -30 to +80 °C, this version is suitable for reliable room temperature detection.
This room resistance thermometer is designed for temperature measurement in indoor environments and is particularly suitable for HVAC applications. With a Pt100 temperature sensor in three-wire configuration and an operating range from -30 to +80 °C, this version is designed for reliable temperature detection in typical room-related applications.
Technical Data
- Design: Room resistance thermometer
- Measuring insert: 1 x Pt100
- Circuit type: Three-wire configuration
- Transmitter: none
- Operating temperature: -30 to +80 °C
- Protection class: IP20
Advantages and technical features
- suitable for classic room temperature measurements
- well suited for HVAC applications
- three-wire configuration for more accurate temperature measurement
- suitable for temperatures from -30 to +80 °C
Its strengths are especially apparent wherever temperatures in rooms need to be continuously monitored without requiring a complex sensor design. The IP20 protection class makes this version suitable for dry indoor areas where the sensor is primarily used for room temperature detection. This makes the device well suited for classic building services and HVAC applications.
The integrated Pt100 sensor belongs to the proven solutions in temperature measurement technology. In this version, it is designed as a three-wire configuration, which is particularly advantageous when cable influences should be compensated better than with a simple two-wire configuration. This supports the most precise and stable temperature measurement possible during operation.
Since no transmitter is integrated, this version is particularly suitable for applications where the sensor should be connected directly to compatible evaluation or control technology. This can be useful wherever simple and direct integration into existing systems is required.
Typical Areas of Application
- room temperature measurement in HVAC applications
- temperature monitoring in indoor environments
- building services engineering
- ventilation and air conditioning systems
- dry indoor areas with low mechanical stress
