Thermocouple sensor

Thermocouples comprise two conductive wires made of different materials, which are connected at one end and which facilitate temperature measurement due to the thermoelectric effect. The voltage generated by this effect is known as thermoelectric voltage, the level of which depends on the materials used. A wide range of materials can be used (types "T", "E" , "J" , "K" or "N"). However, it is important to ensure that the connections and cables used are made of the same material as the thermocouple. The type of thermocouple can be detected based on the colours of the casing or lines.


Allmetra also offers thermocouples featuring stainless sheathed thermocouple lines bent into all possible contours and also equipped with fitted flanges or screw-in screw connections.


Thermocouples are usually used at higher temperatures of up to 1600°C.  Thermocouples generally respond to temperature more swiftly than resistance thermometers.


A test report in accordance with EN10204 3.1 is available on request for all the sensors in our range, also including, where applicable, an inspection and test plan (IT) or a certificate of compliance in accordance with EN 10204 2.1
