Thermocouples

We supply top of the line temperature sensing devices also known as Thermocouples. A thermocouple is a sensor for measuring temperature. It consists of two dissimilar metals, joined together at one end. When the junction of the two metals is heated or cooled a voltage is produced that can interpreted by a temperature controller, high limit or display device. There are two common constructions for these: Tube and Wire and Mineral Insulated. The tube and wire uses an empty stainless tube with a wire inside which has a welded tip incorporating the wire junction. This construction is typically used to 480ºC. The Mineral Insulated construction uses a highly compacted stainless sheath with solid conductors encased in magnesium oxide insulation. This construction offers a wider variety of diameters, allows for the sensors to be bent in the field and for temperatures to 1200ºC. These sensors are available is a huge range of physical packages with a variety of lead wire, housing, and mounting options.

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".
