TE PTF Temperature Elements Connection Techniques

In regards to connecting the thin film RTD series from TE, the manufacturer had provided some information as a reference.

Connection techniques

The preferred connection technique will depend upon the type of lead wire used to manufacture the element. For Au-coated Ni wire, the preferred connection techniques include either welding, brazing or crimping. Some recommendations would include

  • Laser welding: A laser lap or butt weld is the preferred connection technique.
  • Ultrasonic welding: Prior to welding, the leads should be bent away from the plane of the element body to avoid damaging the element
  • Spot welding/resistance welding: this is a widely used, reliable connection technique. Please follow the recommendations of the equipment manufacturer.
  • Crimping: Follow manufacturer’s recommendations for settings and ensure crimp materials are compatible with lead wire material.
  • Brazing: During the brazing operation, the temperature that the element is exposed to must not exceed its maximum rated temperature. Heat sink the element leads, if necessary, during brazing, to avoid overheating. The brazing time should be less than 3 seconds.

For elements with Ag-wire the recommended connection techniques would be soldering using a silver-based solder with the appropriate flux. Ensure that solder alloy is compatible with the lead wire material, and that the melting point of the solder is higher than maximum application temperature. All flux should be removed from the element and lead wires.
