Siemens Silicone PTC Thermistor, -30°C Min, +130°C Max

The Siemens Surface Temperature Sensors monitor and transmit changes in temperature to the HVAC control system. The sensor resistance varies proportionally to the actual temperature being measured. The self contained sensors and units with electrical boxes are ideal for measuring pipe surface temperature as a surrogate for actual fluid temperature when it is not possible to retrofit a full immersion type sensor.
