Screw-in resistance sensors are ideal for surface measuring. They are screwed directly into the component and are available with various thread sizes. With limited space, where no straight cable exit is possible the PWF 74 with right-angled exit is an alternative. The Ø 6 x 5 sensor tip is screwed under spring pressure with the help of a M8 nipple into the tool. Standard leads are galvanized copper wires with PTFE and fiberglass insulation covered by stainless steel metal braid.
