Product information "JUMO room resistance thermometers Protection class IP20"
JUMO resistance thermometer for room temperature measurement with Pt100 in two-wire configuration for measuring range 0 to +60 °C
JUMO room resistance thermometer IP20 protection class with transmitter 4 to 20 mA Type: 902520/10-807-1003-1/330, (0..60°C)
The room resistance thermometer with IP20 protection class is suitable for room temperature measurement with direct analog signal transmission. With Pt100 in two-wire configuration and integrated 4 to 20 mA transmitter, this version is particularly suitable for indoor HVAC applications and building automation in the range from 0 to +60 °C.
This version is intended for applications where room temperatures should not only be measured but also transmitted directly as an analog signal to a control or regulation system. The room resistance thermometer operates with 1 x Pt100 in two-wire configuration and is additionally equipped with an analog transmitter with 4 to 20 mA output.

Advantages and technical features of the JUMO room resistance thermometer
- well suited for room temperature ranges up to +60 °C
- no additional external transmitter required
- easy signal processing within the system
- suitable for dry indoor environments
The measuring range is from 0 to +60 °C and in this version is linked to the integrated transmitter. This makes the variant particularly suitable for applications where temperatures in rooms or other indoor areas should be continuously monitored and processed as a standard signal. Compared to narrower measuring ranges, this version provides slightly more flexibility at higher temperatures and is therefore also suitable for warmer indoor environments.
With IP20 protection class, the device is intended for dry indoor areas. This makes it well suited for classic room applications in HVAC systems where no higher protection class is required. The integrated transmitter is especially practical where a direct 4 to 20 mA signal is required on the system side and no additional signal conversion is planned.
Typical Areas of Application
- room temperature measurement in HVAC applications
- building automation
- heating, ventilation and air conditioning systems
- indoor environments with analog signal transmission
- indoor areas with a slightly extended temperature range
