Temperature measurement by resistance thermometers relies on a property common to all conductors and semiconductors, which is the variation in their electrical resistance in relation to temperature change. PT100 sensor has a resistance of 100 ohms at 0 °C and the coefficient of variation is 0.00385 ohm per degree centigrade. The technology made to meet modern demands in accuracy is based on thin platinum layers on a ceramic substrate (thin-film resistors).
Since the resistance of the sensor is the total of the resistance of the connecting cables (variable with temperature), a three-wire system is used to cancel out the error.
The PT100 Easy-up probes are assigned a numeric code that once inserted allows the Pixsys controllers to automatically set the main operating parameters.
