JUMO Outdoor Resistance Thermometer with Pt100 in Two-Wire Circuit for Measuring Range -50 to +90 °C
JUMO Outdoor Resistance Thermometer Protection Class IP65 - Type: 902520/15-361-1003-1/903
The resistance thermometer is suitable for temperature measurements outdoors and in environments exposed to moisture. Equipped with a Pt100 sensor in a two-wire circuit, a measuring range of -50 to +90 °C, and an IP65 cable gland, this version is designed for reliable outdoor temperature measurement in HVAC applications.
With protection class IP65, this version is intended for outdoor temperature measurements and other installation locations where the housing must be reliably protected against dust and moisture. This JUMO outdoor resistance thermometer is therefore particularly suitable for HVAC applications in outdoor environments.
Technical Data
- Version: Outdoor resistance thermometer
- Measuring insert: 1 x Pt100
- Circuit type: Two-wire circuit
- Transmitter: without
- Operating temperature: -50 to +90 °C
- Protection class: IP65
- Special feature: Cable gland (IP65)
Advantages and Technical Features
- well suited for outdoor temperature measurements
- IP65 protection class for increased housing protection requirements
- IP65 cable gland for protected cable entry
An additional advantage of this version is the IP65 cable gland. It supports secure and protected cable entry and is especially useful where the connection point must remain reliably sealed in outdoor or humid environments. This is particularly beneficial for measuring points exposed to weather conditions.
For temperature measurement, the device uses a Pt100 sensor in a two-wire circuit. This proven sensor design is suitable for many standard temperature measurement tasks in HVAC technology. Since no transmitter is integrated, this version is well suited for applications where the sensor is connected directly to compatible evaluation or control systems.
With a measuring range of -50 to +90 °C, this version covers both low outdoor temperatures and warmer operating conditions. This makes it suitable for applications on buildings, in technical outdoor areas, or wherever temperatures need to be monitored under changing environmental conditions.
Typical Applications
- Outdoor temperature measurement on buildings
- Heating, ventilation, and air conditioning systems
- Technical outdoor areas
- Weather-exposed measuring points
- Applications with protected cable entry
- Temperature monitoring in environments with increased protection requirements
