Temperature probe Double end thermal resistance  WZPM2-003  is a temperature sensor that works on the principle of the pyroelectric effect. The pyroelectric effect means that when two different metals or semiconductors are in contact, a potential difference is formed between them, and the magnitude of this potential difference is related to their temperature related. This phenomenon is called the thermoelectric effect.

A RTD is a sensor that measures temperature based on the change in resistance of a metal or semiconductor material. Commonly used thermal resistance materials include metals such as platinum, nickel, and copper, and semiconductor materials such as indium tin and nickel chromium. Among them, the thermal resistance effect of platinum material is the most stable and reliable, so it is widely used in the fields of industry, scientific research and medical treatment.

The working principle of  Temperature probe Double end thermal resistance  WZPM2-003  is to measure temperature by using the influence of temperature on resistance. When the current passes through the thermal resistance, due to the characteristics of its material, the resistance value will change at different temperatures. According to Ohm's law, the relationship between resistance value and current and voltage is R=V/I, so the resistance value of thermal resistance can be calculated by measuring the value of current and voltage, so as to obtain the temperature value.

In general, the resistance value of a thermal resistor has a linear relationship with temperature. Therefore, when using a thermal resistance for temperature measurement, it is necessary to know its temperature-resistance characteristic curve in advance, so as to calculate the corresponding temperature value according to the resistance value.

In a word, Temperature probe Double end thermal resistance  WZPM2-003  is a reliable, accurate and stable temperature sensor, and its working principle is based on the pyroelectric effect and the characteristics of material resistance value changing with temperature. Thermal resistance is widely used in various industrial and scientific research fields, as well as medical and environmental protection fields. "
