3 Wire PT100 RTD Temperature Sensors

PT100 platinum resistance sensor has three leads, can be used A, B, C (or black, red, yellow) to represent the three lines, the three lines have the following rules: The resistance between A and B or C is about 110 Ohm at room temperature, and the resistance between B and C is 0 Ohm , and B and C are straight through inside, in principle, there is no difference between B and C.

The three-wire system is the most common and widely used in the industrial field.

The relationship between temperature and resistance is close to a linear relationship, the deviation is extremely small, and the electrical performance is stable. Small size, vibration resistance, high reliability, precise and sensitive, good stability, long product life and easy to use, and is typically used in conjunction with control, recording and display devices.
