RTD Probes with Transition to Lead Wire

RTD Probes with Transition to Lead Wire provide excellent accuracy with a high level of durability and versatility for rugged and diverse temperature measurement applications.

  • The Transition Fittings provide the ability to make a transition from the smaller bare wire coming out of the RTD probe to larger diameter, insulated and more durable lead wire designs for diverse applications.   
    • Fittings are made from Stainless Steel tube and typically 1/4" Inch (.250" or 6.35 mm) or 3/8" Inch (.375" or 9.5 mm) in diameter.
    • One end of the Metal Tube is firmly crimped or welded to the probe sheath and other end provides the ability to connect a metal spring to ensure Strain Relief of the Lead Wires.
  • Lead Wires can be 2, 3, and 4 Wire Designs for Pt100 (Platinum 100 ohm) or Pt1000 (Platinum 1000 ohm) RTD temperature measurement circuits.
    • Insulations - the most utilized design is wire with Fluoropolymer insulation (PFA or FEP) due to the durability, versatility and temperature range from below zero to to 500 F ( 260 C). Fiberglass Braid provides a higher temperature range to 900 F (500 C) although less durable, at times a protective Stainless Steel Overbraid or Armoured Cable is applied to either insulation.
    • Wire Construction is typically flexible 26 gage or 24 gage (7/34) stranded diameter made with nickel plated copper. Smaller diameters are used at times with silver or tinned plated copper.
    • Outside Diameters of the overall insulated wire typically range 0.075" inches (larger than 1/16" or 1.5 mm) to 0.125" inches (1/8" or 3.2 mm). Armoured cable designs have larger diameters, typically 0.188" (3/16" or 4.5 mm)
