The temperature coefficient of an RTD (resistance-temperature-detector)element is positive. Most stable, linear, and repeatableRTDs are of platinum-metal construction. You can usethe constant 0.00385Ω/Ω/°C to approximate the resistancechange over temperature for the platinum RTD element. Incont...
A resistance temperature detector (RTD) includes a temperature sensing circuit with a conductive element to receive an input signal and produce an output signal that is a function of temperature. The conductive element is formed from a metal having a temperature coefficient of resistance from about ...
RTDs are categorized by their nominal resistance at 0°C. A Pt100 sensor has a temperature coefficient of approximately 0.385 Ω/°C and a Pt1000 has a temperature coefficient that is a factor of 10 greater than the Pt100. Many system designers use these coefficients to get an...

The pressure sensor has sensitivity of 356 ppm/kPa at room temperature, with temperature coefficient of sensitivity of -6507 ppm/K. The temperature sensor has sensitivity of 0.29%/K. The valve and the sensors are tested across a wide range of temperatures, and the effect of temperature on ...
temperature coefficient, nominal resistance, and, to some extent, wiring configuration. Sensor Material Several metals are quite common for use in RTD's, and the purity of the metal as well as the element construction affects its characteristics. Platinum is by far the most popular due to its ...
Temperature Coefficient refers to the rate at which a material's sensitivity to temperature changes. In the context of piezoresistive sensors, it is crucial to consider the Temperature Coefficient of Sensitivity (TCS) to ensure accurate measurements, especially in applications where precise temperature co...
