Mineral-Insulated Thermocouples - JUMO

Due to their specific features, mineral-insulated thermocouples are used in chemical plants, power plants, pipelines, engine building, and test rigs. Inside the flexible and thin-walled sheathed cable, the thermo wires are embedded in compressed and fire-resistant magnesium oxide.

The good thermal transfer between the sheath and the thermocouple enables short response times (t0.5 as of 0.15 s) and excellent measuring accuracy. The vibration-resistant construction guarantees a long operating life. The smallest bending radius is 5 times the outer diameter. With a diameter of 0.5 to 2.0 mm, the minimum insertion length (EL) is ≥ 50 mm; with a diameter of 3.0 to 6.0 mm, the EL is ≥ 100 mm.

It is designed to be insulated from the sheath as standard. The measuring insert is equipped with thermocouples (elements) according to DIN EN 60584 and/or DIN 43710. Versions with two thermocouples are also possible.

Key features

Test pressure: check for leaks at the measuring point at 40 bar (helium).

Leakage resistance: thermocouple against sheath at room temperature and lengths < 1 m 200 MΩ, with lengths ≥ 1 m 200 MΩ × m.

Application-specific insertion length

Flexible sheath cable

Vibration resistant measuring insert

Fast response time

Connection: Ferrules according to DIN 46228, multi-pole plug connector

Compensating cable: Silicone, PTFE, metal braiding

Process connection: Screw connection G 1/2, screw connection G 3/8

Protection tube: Stainless steel 1.4541, Inconel 2.4816 (Inconel 600)

Measuring insert: J, K, L
