The DT-series silicon diode temperature sensor we launched uses a special silicon diode chip, which has more stable low-temperature operating characteristics than the silicon diodes on the market before.In the temperature measurement range of 1.8K~325K, the DT-series follows the standard voltage and temperature response curve, and has a higher temperature measurement sensitivity below 30K. It is suitable for extremely low temperature measurement. At the same time, it has good interchangeability and does not require separate calibration in general applications.
