Industrial Thermocouples Views
Thermo Electric Industrial Thermocouple & RTD Assemblies are used in the process and power industries where thermocouples or RTDs are installed in pipe lines or vessels. This type of assembly consists of three basic parts, the connection head, sensing element and a Thermowell or protection tube. Selecting the proper assembly involves consideration of several factors including process temperature, environment, fluid or gas pressure, pipe or vessel size and flow velocity.
Approximately 300 types of thermocouples have been researched or used, but among these only eight have gained popularity and are in common industrial use. These thermocouples are listed in Table 1 as either base metal or noble metal, depending on whether a noble or precious metal such as platinum is included in the thermocouple material. Two of the eight thermocouples, type K and N, are identical in most characteristics. In fact, type N is a new thermocouple that has been developed to overcome some of the drawbacks of the type K thermocouple such as atomic ordering, drift, and oxidation problems. The type E and type J thermocouple have better relative output than type K, although type K is more widely used than type E or J. One reason for this is the better linearity offered by the type K thermocouple.
Vulcan Electric designs and produces a wide assortment of thermocouple constructions for industrial applications. Many of these products are custom designed for a specific process requirement. We begin with our decades of engineering experience to ensure complete thermocouple design compatibility. Then we select premium materials and components for durability and maximum longevity. These heavy-duty thermocouples are designed for use in severe and complex process applications where performance reliability is critical. We have the capability to design and manufacture numerous calibration types, configurations, and material combinations.
