PT100 is a thermistor with positive temperature coefficient. As the temperature rises, the resistance of the resistor becomes larger, and its resistance is 100 ohms at 0 degrees.
The reason why PT100 is widely used is not only because the temperature measurement range is relatively wide, but also because its linearity is very good, that is, every time the temperature increases by one degree, the value of its resistance increase is basically the same, about 0.38-0.39 ohm corresponds to 1 degree , basically take 0.3851Ω/℃.
Temperature range: -200℃~450℃
If there's any temperature sensor or RTD inquiry, welcome contact with Sinton and we are professional with better services and high quality temperature sensor.
Sinton Group mainly make kinds of electric heating elements and temperature sensor: For example , cartridge heater,hot runner coil heating element, tubular heater element, ceramic emitter, ceramic plate heating element, aluminium casting heater, mica band heater, ceramic band heating elements, Flexible ceramic heating pad, kapton heater, PI film heating elements, resistance wire, thermocouple, Pt100 etc. Also we make industrial heaters for example air duct heater, pipeline heater, oil circulation heater, drying oven etc. All of our heaters and temperature sensor can be OEM and now we have acquired CE certificate for our heating elements.
