Head Assembly Explosion-proof gasket screw-cover head in either cast aluminum or cast iron, with a simplex or duplex terminal block as required. Extension Assembly Nipples and union in 1/2" standard weight steel. Standard lengths are 4" and 6", with 3", 5", 7" and 8" also available. Thermocouple Element Available in all calibrations and junctions. Choice of insulated metallic sheath or ceramic insulated element. Thermowell or Protection Tube Assemblies are available with either Thermowells, Protection Tubes, or Uniwell Designs. length — i.e. the length required to pass through walls, pipe fittings, etc. — is taken into account when choosing the necessary insertion length. Our engineering staff is available to help you should you have further application questions. Our tapered thermowells provide greater rigidity than straight shank styles. They are well-suited to applications of high fluid velocity. The thermowells shown on the following pages are available in standard bore diameters of .260" for thermocouple elements to 14 gauge wire and .385" for thermocouple elements to 8 gauge wire. Both are suitable for use with metal sheathed elements of compatible diameters. Thermo-Couple Products company offers thermowell assemblies in a wide variety of materials, lengths and diameters to meet your particular application conditions including: temperature, mechanical strength, corrosion, atmosphere, dry or liquid immersion; velocity of measured medium and length of service. Included in our thermowell series are standardized wells of threaded, ANSI flanged, Van Stone and weld-in types. Threaded wells are made in readily welded or brazed materials for installations requiring seal welding or brazing. The pipe thread provides the mechanical strength, the weld merely seals. ANSI flanged wells consist of a bar-stock well which is permanently welded to a top quality flange. Standard construction uses primary “J” groove weld and a bevel groove secondary weld. Both welds are machined to produce a clean fillet. This double welded construction eliminates possibility of crevice corrosion since no open joints are exposed from either inside or outside the installation. Socket weld types of wells can be installed easily by merely welding into place to form a clean and tight connection. The insertion length “rule of thumb” of ten diameters is not always practical when installing thermowells. Care should be exercised to make certain that the sensitive tip is totally immersed into the medium being measured.
