Platinum resistance temperature sensor
Product Description
Introduction:
The platinum resistance temperature sensor measures temperature by utilizing the characteristic that the resistance of special metal changes with the temperature. The display instrument will indicate the temperature value corresponding to the resistance value of platinum resistance. When there is a temperature gradient in the measured medium, the measured temperature is the average temperature in the medium layer within the range of the temperature sensing element. The platinum resistance temperature sensor is the most precise and stable temperature sensor. Its linearity is better than that of thermocouple and thermistor, and it is suitable for application fields with strict requirements on precision.
Features: High precision and good linearity ; Good sealing performance and capable of withstanding 150 meters water depth; Digital bus interface, can be in series with 250 sensors ; Unique interface mode for convenient wiring.
Application: Ground temperature inspection; Ocean temperature monitoring.
