Siemens 536-777-25 Immersion Temperature Sensor, 100k Ohm Thermistor

Siemens 536-777-25 Immersion Temperature Sensor is a high precision instrument to measure temperature in HVAC systems. This sensor's 100k Ohm thermistor or 1000 Ohm sensing element has performs with accurracy in the temperature range from 30°F to 240°F. Perfect for residential and commercial HVAC applications, the sensor is constructed for harsh weather conditions and housed in a solid metallic enclosure. This sensor works like it senses temperature changes in the water or air it’s submerged in and turns that into a resistance signal the HVAC management system can read. The great sensitivity of the sensor makes possible the monitoring and control of heating and cooling processes, thereby improving system efficiency.
