TSM-1 — thermocouple with metal thermowell

straight design to DIN EN 50446 · type K, N, S, R, B · up to +1,250 °C

Design (example) · dimensions in the data sheet

Straight thermocouple with a metal thermowell to DIN EN 50446 for furnace and heat treatment plants – with thermocouple wire in ceramic insulation or a sheathed measuring insert. Head, thermowell and thermocouple are standardised individual parts: the thermowell stays replaceable during operation, the measuring insert can be retrofitted separately.

Hardening, annealing and tempering furnaces
Melting and holding furnaces, foundry
Glass, ceramic and cement plants

Standard designation to DIN EN 50446, for example thermocouple EN 50446 – AMK 22 Q U – 1 K 1 – 1.38 – 1000: version, Ø and material of the outer and inner thermowell, number and type of thermocouples, class, Ø and nominal length.

Related series

Above +1,250 °C or in an aggressive furnace atmosphere the TSK with ceramic thermowell does the job (up to +1,600 °C). For measuring points to DIN 43772 with a replaceable sheathed measuring insert see the overview of thermowell thermocouples. GHI supplies spare thermowells as the RMR-A / RMR-C series.
