The Pt100 function simply explained

The Pt100 function simply explained

Platinum sensors have established themselves as resistance thermometers. The correlation between temperature and resistance in platinum thermometers is not proportional but is described by a higher order polynomial. With: = Resistance of the thermometer = Resistance of the thermometer at 0 °C = Individual parameters of the

How do thermocouples work?

Thermocouples belong to a large group of thermometers. Simplified described, a thermocouple is made of two simple wires. They are mainly used for industrial measurements in large quantities. They are most often used at high temperatures. But how can you measure temperatures with two wires?   Principle

How do resistance thermometers work?

Resistance thermometers are widely used and are often used for more precise temperature measurements. The usual temperature range of them is between about -50 °C to 600 °C. However, there are also special applications where resistance thermometers are used from -200 °C to over 1000 °C [1].
