Resistance Temperature Detector (RTD) เครื่องตรวจจับอุณหภูมิความต้านทาน

Product Instruction

Thermal resistance is the most commonly used in the low&middle temperature zone of temperature detect. Thermal resistance measurement is based on the metal conductor resistance increases with the temperature of the characteristics of this feature to the temperature measurement. Its main characteristic is high measurement accuracy and stable performance. The measurement accuracy of platinum thermal resistance is the highest, it is not only widely used in industrial temperature measurement, and was made into a standard benchmark. Thermal resistance mostly made of pure metal materials, like platinum and copper, are the most widely used materials, in addition, people now begin to use nickel, manganese and rhodium materials to produce thermal resistance.

Product Feature

1. Pressure spring-type temperature sensing element, anti-vibration performance;

2. High precision temperature measurement;

3. High mechanical strength, high temperature and good pressure resistance;

4. Imported thin film resistor components, reliable performance and stability.

Applications

Currently the most widely used thermal resistance materials are platinum and copper: Platinum resistance: high precision, suitable for neutral and oxidizing media, good stability, with a certain non-linear, the higher the temperature the smaller the rate of change in resistance; Copper resistance in the temperature range of resistance and temperature linear relationship, a large number of temperature lines, suitable for non-corrosive media, more than 150 easily oxidized.
