Measuring insert for thermocouples

Measuring inserts for resistance thermometers and thermocouples are essential components in temperature measurement technology that enable precise temperature measurements. They typically consist of a protective tube that surrounds the temperature sensor itself - be it a thermocouple or a resistance thermometer - and protects it from mechanical damage and chemical influences. These inserts are designed so that they can be easily replaced if necessary without having to dismantle the entire measuring system, making maintenance work easier and minimizing downtime.

Thermocouples consist of two wires of different metals that are connected at a measuring point and generate a voltage that is proportional to the temperature difference. Resistance thermometers, on the other hand, use the temperature-dependent resistance of metals, usually platinum, to determine the temperature. Measuring inserts for thermocouples and resistance thermometers are available in various designs, including rigid and flexible versions. 

The selection of the appropriate measuring insert depends on various factors, including the temperature range, the ambient conditions and the required accuracy. For example, SAB Bröckskes offers measuring inserts both as thermocouples in various types (e.g. type K, J, L) and as resistance thermometers (e.g. 1x or 2x Pt100), each in different versions and with specific properties.
