These RTD's are constructed with an epoxy filled transition to lead wire. This transition allows for higher temperature construction in the metal sheathed portion of the RTD assembly along with providing a mounting point for flexible armor protected leads. The RTD lead configuration can be 2-wire or 3-wire with either single or dual elements. The 3/16" O.D. 316 SS sheath (with optional 45° or 90° bend) has a bayonet cap and spring positioned according to the "U" length shown above.
