RTD Air Water Temperature Sensor

The platinum resistance temperature sensor is a thermometer that measures temperature by adjusting its resistance. The resistance-temperature polynomial function R expresses the standard relationship between resistance and temperature, which is supplied in the form of a graduated table because the characteristic curve of the platinum resistor is non-linear (t).

RTD Air Water Temperature Sensor

The platinum resistance temperature sensor is a temperature sensor made by using its resistance as a function of temperature. Since the characteristic curve of the platinum resistor is non-linear, the standard relationship between resistance and temperature is given in the form of a graduated table, and is expressed by the resistance-temperature polynomial function R(t). But in the actual measurement, it is convenient to use the temperature-resistance function T(r) for measurement and calculation. The actual use shows that the calculation of this method produces less error, and can improve the running speed and control precision of the temperature measurement and control system well.

 

The Features of RTD Air Water Temperature Sensor

  • When using a platinum resistance temperature sensor, it should be noted that there should be good insulation between the temperature sensing elements (double structure) and between the temperature sensing element and the ground, otherwise it will directly affect the accuracy of the measurement results, and even affect the instrument. of normal operation.
  • When using a platinum resistance temperature sensor for temperature measurement, it is necessary to select the correct type, install and use it reasonably, try to manage various external influences as much as possible, reduce additional errors, and achieve the purpose of accurate measurement and simplicity.
  • Platinum resistance temperature sensor is a temperature sensor used to measure air, soil and water. The sensor is composed of a platinum thermal resistance element and a process-treated protective sleeve, and a four-core shielded signal cable is used to lead out from the sensitive element for measurement. Usually, it can be measured by using a four-wire measurement method to reduce measurement errors caused by wire resistance.
  • Platinum resistance temperature sensors have excellent interchangeability and long-term stability, and are widely used in meteorological and environmental protection departments
