Product information "JUMO room resistance thermometers Protection class IP20"

JUMO room resistance thermometer with Pt1000 in two-wire configuration and operating temperature range -30 to +80 °C

JUMO room resistance thermometer protection class IP20 Type: 902520/10-572-1005-1/000

The room resistance thermometer with IP20 protection class is suitable for temperature measurement in indoor areas and HVAC applications. With Pt1000 in two-wire configuration and a measuring range from -30 to +80 °C, this version is designed for reliable room temperature detection in dry indoor environments.

The focus of this version is on simple and direct temperature measurement without an integrated transmitter. This makes the thermometer particularly suitable wherever the sensor should be connected directly to compatible evaluation or control technology. Especially in straightforward building services and HVAC applications, this version provides a practical solution.

Compared to Pt100 versions, this variant uses a Pt1000 sensor. This can be particularly beneficial where the control or evaluation technology is designed for Pt1000 or where this sensor version is preferred. The two-wire configuration makes this version a classic solution for many common room temperature measurement tasks.

With IP20 protection class, this variant is designed for dry indoor environments. It is therefore especially suitable for applications where room temperature should be continuously monitored without requiring a higher protection class.
