Temperature Sensors - RTD (Resistance Temperature Detector) plays an important role in many industrial and electronic applications. It is a type of temperature-sensitive device that utilizes the principle of resistance thermistors to measure temperature changes. As temperature changes, the resistance of the RTD changes according to a pre-determined valve over a specified range. One such temperature sensor is the PTS080M1B500RP100. This article outlines the application field and working principle of the device.

Application Field
The PTS080M1B500RP100 is a type of Resistance Temperature Detector that specifically uses a platinum-based alloy to measure temperatures. It is perfect for high-precision temperature measurements and processes requiring low power. It is commonly used for precision temperature measurement in telecom, food, pharmaceutical, medical, electronics, petrochemical, and aerospace industries. Its high temperature stability, accurate temperature measurement, and low power requirements make it one of the best temperature sensors in the industry.

Working Principle
The PTS080M1B500RP100 utilizes the effect of temperature coefficient resistance. This effect relates the resistance of the device to temperature. As temperature increases, the resistance of the device also increases. As the temperature decreases, the resistance decreases. This relationship is very linear, meaning that the resistance change is constant over a specified range of temperature. The device is composed of a platinum-based alloy which is calibrated to have a temperature coefficient of resistance of 0.00393 ohms/ ohms per degree Celsius. This is the device’s temperature coefficient of resistance (TCR).

The temperature coefficient of resistance (TCR) is used in conjunction with the device’s resistance versus temperature (R/T) curve. This curve shows the relationship between the device’s resistance and temperature. Knowing the device’s resistance at a certain temperature, the temperature of the sensor can be determined. By using the device’s R/T curve, temperature can be accurately measured from -50°C to +250°C.

To accurately measure the temperature of the sensor, a potentiometer is used to adjust the device’s resistance to the desired value. The potentiometer is connected to a measurement device such as an oscilloscope or a computer with a USB port. The potentiometer can then be used to adjust the device’s resistance to the desired value. The device’s resistance will then be read from the measurement device and compared to the device’s R/T curve, which will then be used to determine the temperature.
