1 FURNACE TUBE TEMPERATURE THERMOCOUPLES Whenever thermocouple must be welded in plce it is dvisble to use weld pd nd weld clips to protect ginst burn-through of the sheth mteril during field instlltion. Sndelius weld pds, weld clips nd weld pd covers re vilble in wide rnge of styles nd mterils. Stndrd W, W nd W style weld pds mesure / x / x /8. Inconel 600 or 0SS hve proven to be excellent choices for most furnce pplictions. Other mterils re vilble on request. Sndelius Style WB Sndelius Style WD Flt Formed Designtion Add forming informtion s required If forming is specified, the thermocouple sheth will ly prllel to the process tube. Designtion Add forming informtion Formed so the thermocouple sheth wrps round the process tube. The mount of rc desired s well s the tube size should be specified on your order. (Shown with Fig. bend =90º). Note L length of the T/C is mesured from the center line of the tube. Sndelius Style WC Tip Mounted Weld Pd Designtion Sndelius Style WE Designtion Add forming informtion s required W6E Wedge-Shped Weldment This design offers n lterntive to the trditionl weld pd for 0.7 or lrger dimeter sheth sizes. It incorportes specilly shped weldment to keep the thermocouple junction in contct with the furnce tube surfce. (W6E is shown with Fig. bend =90º).

This process forms mesuring junction which is n integrl prt of the end cp nd electriclly grounded to the sheth. The most common junction style, grounded junctions protect the thermocouple conductors from contmintion nd offer fst response times. Order Symbol: G-Single or Dul Element R-REMOTE OR UNGROUNDED JUNCTION END CAP INSULATION JUNCTION SHEATH CUT AWAY VIEW The conductors re first junction welded together. Prior to cp welding the sheth, the junction is covered with insulting mteril to insulte it from the sheth nd end cp. Remote junctions protect the thermocouple conductors from both contmintion nd outside electricl interference. They re used whenever electricl isoltion of the element is desirble.
