Mineral-Insulated Thermocouples
According to DIN 43710
and DIN EN 60584
• For temperatures between -200 to +1200 °C
• Flexible sheath cable with vibration-resistant measuring insert
• Protection tube diameter as of 0.5 mm
• Quick response time
• Application-specific insertion length
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 thermowires are embedded in compressed and fire-resistant magnesium
oxide.
The good thermal transfer between the sheath and the thermocouple enables short response
times (t
0.5
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.
The thermocouples are 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.
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 M Ω , with lengths ≥ 1 m 200 M Ω × m.
