Temperature is measured using a platinum thermal resistance sensor made of PT100 or PT1000. Typically, it is used in conjunction with control, recording, and display devices. The temperature range is -50°C to 200°C. in order to fully realize the measurement, control, and regulation of temperature.
Pt100, Pt1000 platinum thermal resistance is used as a sensor for measuring temperature. It is usually used in conjunction with display instruments, recording instruments and control devices. The measuring range is -50℃~200℃. So as to realize the whole process of temperature measurement, control and regulation.
The Features of Motor PT100 PT1000 Platinum Resistance Temperature Sensor
Imported thin-film platinum thermal resistance elements are used, and the product quality meets the international standard of IEC751. The resistance value of platinum resistors changes with temperature. 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.
The Working Principle of Motor PPT100 PT1000 Platinum Resistance Temperature Sensor
The Pt100 platinum resistance temperature sensor measures temperature by using the characteristic that the resistance value of metal platinum changes accordingly when the temperature changes, and the display instrument will indicate the temperature value corresponding to the resistance value of the 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 where the temperature sensing element is located.
The Installation Notes of Motor PT100 PT1000 Platinum Resistance Temperature Sensor
Install the sensor in the place where the temperature needs to be detected (usually installed in the winding), do not let the sensor lead wire bear the tension, the lead wire should be connected in the motor junction box, and the shielding wire should be grounded (connected to the motor shell). 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.
