Mineral Insulated Metal Sheathed Resistance Thermometer Detectors (MIMS RTD’s) supplement the Mineral Insulated Metal Sheathed Thermocouples (MIMS TC´s), which are tried and tested over many years. MIMS RTD´s can be applied for temperatures from -100 °C up to +550 °C. They combine the advantages of the MIMS RTD´s with those of the bendable mineral insulated metal sheathed thermocouples.
As supply wires mineral insulated metal sheathed cables are used. The supply wires are embedded in a MgO compact insulation and surrounded by a metal sheath of stainless steel. The compact insulation fixes the wires completely so that they cannot be damaged neither by vibration nor by strong bending. Short circuits between the wires or between them and the metal sheath are impossible.
The minimum bending radius depends on the outside diameter of the MIMS cable. About 5 ... 7 times the outer diameter is a practicable standard value.
The measuring resistor itself complies with the requirements of the DIN EN 60751 standard.
If in special cases, for example in the case of great lengths, the inner conductor resistance increases more than usual, the resistance is shown on the identification plate.
The temperature sensitive length of the RTD is typically 35 mm. Different lengths can be supplied upon request.
