Jumo Outdoor Resistance Thermometer with Pt1000 in Two-Wire Circuit with Operating Temperature -50 to +90 °C
JUMO Outdoor Resistance Thermometer Protection Class IP65 Type: 902520/15-361-1005-1/903
This resistance thermometer from JUMO is suitable for temperature measurements outdoors and in environments exposed to moisture. Equipped with a Pt1000 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.
This version is therefore intended for outdoor temperature measurements where the housing must be reliably protected against dust and moisture.
Technical Data
- Version: Outdoor resistance thermometer
- Measuring insert: 1 x Pt1000
- 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 of the JUMO Outdoor Resistance Thermometer
- well suited for outdoor temperature measurements
- IP65 protection class for increased housing protection requirements
- IP65 cable gland for protected cable entry
- Pt1000 sensor for compatible control and evaluation systems
Unlike Pt100 versions, this model operates with 1 x Pt1000 in a two-wire circuit. This is especially useful when the connected control or evaluation system is designed for Pt1000 or when this sensor configuration is preferred. Since no transmitter is integrated, this version is well suited for applications where the sensor is connected directly to compatible evaluation or control systems.
A practical advantage is the IP65 cable gland. It ensures protected cable entry and supports reliable sealing of the connection point. This is especially important for outdoor applications or technically demanding environments to ensure reliable measurement performance under changing environmental conditions.
Typical Applications
- Outdoor temperature measurement on buildings
- Heating, ventilation, and air conditioning systems
- Technical outdoor areas
- Weather-exposed measuring points
