Reckmann D-58137 Thermocouple Assembly

Reckmann D-58137 Thermocouple Assembly is a straight measuring insert (Messeinsatz) configured with two Fe-CuNi (Type J) thermocouple elements, built to DIN EN 60584 standards and designed to fit Reckmann protection armatures and size-B connector heads with a ceramic socket (Ø 42 mm). The version accommodates 1x or 2x Fe-CuNi (Type J) elements, and uses retention springs to ensure consistent contact within the housing. When used with stainless steel protection tubes, the maximum recommended operating temperature is 850 °C. The outer protective tube diameter can be 3, 6, or 8 mm, enabling compatibility with a range of installation geometries. This product sits within Reckmann’s thermocouple assemblies portfolio, which includes straight and bendable configurations across multiple thermocouple types (K, J, L) per DIN EN 60584 or DIN 43710, and is intended for industrial temperature monitoring and control applications where two Fe-CuNi sensors are required in a compact assembly.
