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 900ºF. 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 2200ºF. These sensors are available is a huge range of physical packages with a variety of lead wire, housing, and mounting options.

RTD’s (Resistance Temperature Detectors)

(RTDs) are temperature sensors that contain a resistor that changes resistance value as its temperature changes. RTDs are also available in a Tube and Wire and Mineral Insulated construction. They are more accurate than thermocouples and are typically used for temperature sensitive and laboratory applications. We offer these in a variety of constructions and physical packages but are constrained by the size of the resistor beads. There are restrictions to the diameter and lengths of the available constructions.
