Wall-Mounted Resistance Thermometer by JUMO with Pt100 and Analog Transmitter with Measuring Range -30 to +60 °C
JUMO Wall-Mounted Resistance Thermometer with Remote Protection Tube Protection Class IP65 Type: 902520/23-474-1003-1/330,(-30..60°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, and a measuring range of -30 to +60 °C, this version is particularly suitable for wall-mounted measuring points where the temperature value should not only be measured but also transmitted directly as a standard analog signal. The wall-mounted resistance thermometer is equipped with a remote protection tube. This makes the version especially interesting for HVAC applications where the measuring point is located at some distance from the housing and the signal should be transferred directly to a control or regulation system.
Technical Data
- Version: Wall-mounted resistance thermometer with remote protection tube
- Measuring insert: 1 x Pt100
- Circuit type: Two-wire circuit
- Transmitter: 1 x analog, output 4 to 20 mA
- Measuring range: -30 to +60 °C
- Note: Measuring range only in combination with transmitter
- Protection class: IP65
Advantages and Technical Features
- remote protection tube for more targeted temperature measurement
- integrated 4 to 20 mA transmitter for direct signal transmission
- well suited for wall-mounted measuring points with a spatially separated measuring location
- suitable solution for building automation and HVAC applications
- no additional external signal conversion required
The remote protection tube is an important advantage of this version. It enables the temperature to be measured closer to the actual measuring point while the housing remains mounted separately on the wall. This is especially practical when the temperature should not be measured directly at the housing location but with some distance from it.
In addition, the integrated transmitter with a 4 to 20 mA output allows the temperature signal to be processed directly as a standardized current signal. Especially in building automation, HVAC systems, and other technical applications, this is beneficial when no additional external transmitter is planned on the system side. The relevant measuring range for this version is -30 to +60 °C and applies in combination with the transmitter.
With protection class IP65, the housing is well protected against dust and water. This makes the version suitable for technically demanding environments where a more robust wall-mounted solution is required than standard room sensors can provide.
Typical Applications
- Wall-mounted measuring points in HVAC applications
- Building automation
- Heating, ventilation, and air conditioning systems
- Applications with direct signal transmission to controllers or control systems
- Measuring points with a slightly remote measuring location
