PT100 EASY-UP
Diameter 6mm, three-wires cable
Temperature measurement by resistance thermometers relies on a feature which is common to all conductors and semiconductors: their electrical resistance is subject to variation with changing temperature. PT100 sensor has a resistance of 100 ohms at 0 °C and the coefficient of variation is 0,00385 ohm each °C. The technology to meet requirements of accurate measurement is based on thin platinum layers on a ceramic substrate (thin-film resistors).
A three-wires system is used to compensate the error arising from resistance of connecting cables combined with resistor of the sensor itself.
Easy-Up PT100 are linked to a numeric code (password) to be entered on selected Pixsys controllers in order to set automatically the main operating parameters (type of sensor, measuring range...).
