The thermocou- ple wires are embedded in compressed fire-resistant magnesium oxide inside the flexible thin-walled sheath. The excellent heat transfer between the sheath and the thermocouple enables short re- sponse times (t from 0.15sec) and high measurement accuracy. The shock-proof con- 0.5 struction ensures a long life. The minimum bending radius is 5 x the external diameter. The minimum fitting length EL is 50mm for 0.5mm to 2.0mm dia., and 100mm for 3.0 to 6.0mm dia. The thermocouples are normally insulated from the sheath. The measuring insert is fitted with thermocouples to EN 60 584 or DIN 43 710. Versions with two thermocouples are also available. Test pressure: 40 bar (helium) leakage test at the measurement point. Insulation resistance: thermocouple against sheath at ambient temperature for lengths up to 1m: 200M , for lengths 1m and above: 200M xm.
