The plug-in thermocouple can be used in conjunction with the standard DIN EN 14597 (DIN 3440), tested temperature control and limiting devices, in heat transfer systems according to DIN 4754. With the help of the Seebeck effect, it can be used to measure the temperature in the operating medium air. The thermocouple is therefore particularly suitable for applications in heating, furnace and apparatus construction. As a double thermocouple 2x NiCr-Ni K according to DIN EN 60584 (class 2), it is designed for temperatures from -35 to +800 °C. The connection head in form B (M24 x 1.5) is made of die-cast aluminum and can withstand ambient temperatures up to 100 °C. The 15 mm thick protective tube is made of stainless steel 1.4571 and is 40 mm long at the tip and has a diameter of 5.5 mm. The stainless steel material protects the measuring insert against chemical influences and mechanical damage. The installation length can be varied between 50 and 460 mm using the adjustable stop flange. The thermocouple is intended exclusively for temperature measurements in gaseous media (air).
