FeCuNi Temperature sensor

An FeCuNi temperature sensor is a temperature sensor made of an iron-copper-nickel alloy. These sensors are characterised by high sensitivity and accuracy, especially in low to medium temperature ranges.

They are often used in industrial applications, including melting equipment, where precise temperature monitoring is critical.

The FeCuNi temperature sensor works on the basis of the thermos-electric effect, in which an electric voltage is generated by temperature differences. The specific alloy ensures stable and reproducible measurement results, which is essential in process monitoring.

The thermos-electric effect describes the direct conversion of temperature differences into electrical voltage and vice versa. It is based on the fact that charge carriers (electrons or electron defects) are moved by a temperature gradient in an electrical conductor or semiconductor.

In addition to FeCuNi temperature sensors, models with PT100 or Ni120 technology are also used. These are based on a different measuring principle (resistance thermometer) and also offer high precision, but with different properties in terms of temperature range, sensitivity and area of ​​application.
