Active sensor for measuring air temperature in ventilation ducts.

They are used in heating, ventilation, and air conditioning systems as:

• Supply or exhaust air temperature sensor 
• Limiting sensor, e.g., limiting the minimum supply air temperature 
• Reference sensor, e.g., for changing the desired room temperature value depending on the outdoor temperature 
• Dew point temperature sensor 
• Measuring sensor, e.g., measuring the value of the controlled variable into the control system 

Features: 

• Capillary length: 0.4 m 
• Measurement range: -50...+50°C
• Output signal: DC 0...10 V
• Sensor type: Pt 1000
