Product information "JUMO wall resistance thermometer with outdoor sensor Protection class IP65"
JUMO Wall-Mounted Resistance Thermometer with External Sensor, Pt100 and Analog Transmitter for Measuring Range -40 to +80 °C
JUMO Wall-Mounted Resistance Thermometer with External Sensor Protection Class IP65 Type: 902520/22-474-1003-1/330,(-40..80°C)
The wall-mounted resistance thermometer is suitable for HVAC temperature measurements with direct analog signal transmission. Equipped with Pt100 in a two-wire circuit, an integrated 4 to 20 mA transmitter, external sensor, and a measuring range of -40 to +80 °C, this version is designed for wall-mounted measuring points where the temperature should be measured directly at the measuring location and transmitted simultaneously as a standard analog signal.
Technical Data
- Version: Wall-mounted resistance thermometer with external sensor
- Measuring insert: 1 x Pt100
- Circuit type: Two-wire circuit
- Transmitter: 1 x analog, output 4 to 20 mA
- Measuring range: -40 to +80 °C
- Note: Measuring range only in combination with transmitter
- Protection class: IP65
Advantages and Technical Features of this JUMO Wall-Mounted Resistance Thermometer
- external sensor for more direct temperature measurement at the measuring point
- IP65 protection class for increased housing protection requirements
- suitable solution for wall-mounted measuring points in technically demanding environments
- no additional external signal conversion required
The external sensor is particularly useful where the temperature should not only be measured around the housing but as close as possible to the actual measuring location. This is an advantage for wall-mounted measuring points where more direct temperature measurement is desired compared to versions with an internal sensor.
In addition, this version features an analog transmitter with a 4 to 20 mA output. This allows the temperature signal to be transmitted directly to suitable controllers, regulators, or building management systems. Especially in HVAC technology, this is practical when a standardized current signal is required on the system side and no additional external signal conversion is planned.
The measuring range is -40 to +80 °C and applies to this version in combination with the integrated transmitter. This makes the version suitable for cooler outdoor areas or applications with greater fluctuations in ambient temperature.
With protection class IP65, the housing is well protected against dust and water. This makes the version particularly interesting for technically demanding installation locations where a robust wall-mounted solution with direct signal transmission is required.
Typical Applications
- Wall-mounted measuring points in HVAC applications
- Building automation
- Heating, ventilation, and air conditioning systems
- Protected outdoor areas
- Technical indoor areas with direct signal transmission
JUMO order code:
A JUMO order code uniquely identifies a specific measuring instrument or component based on its configuration.
