In Mineral Insulated (MI) thermocouples, elements are surrounded by compact inorganic insulation (MgO) and housed in stainless steel or heat resistant alloy sheath to protect it from environment. MI thermocouples have a lot of advantages as compared to conventional beaded thermocouples. These thermocouples are available in long lengths which can easily be wound into coils making them easy to transport. They can be flattened or bends without affecting the sheath or the cores. This flexibility enables them to be easily installed. They have a small sheath diameter allowing the thermocouple to be placed in smaller areas. Ceramic is a brittle material and when placed as beads may succumb under conditions with vibrations. MI thermocouples have high vibration strength which make them apt for such applications. These thermocouples are tested to ensure high quality. All assemblies are tested for Insulation resistance, Visual & Dimensional checks, and Single point calibration. Other tests offered "Conductor loop resistance", "Specific temperature calibration", "Nitrogen leak test", "Hot IR test".
