SR504 (NTC) temperature sensor adopts NTC thermistor as temperature sensing element, with the high-precision sealing process production. It has advantages like high sensitivity, stability, corrosion resistance, long life, easy installation. Apply to any high temperature and humidity and other harsh environments. The temperature sensor can quickly and accurately detect the temperature of air and water, and send the signal to the control system to achieve the purposes of precise control the temperature of water and air.
