Screw-in resistance sensors are ideal for surface measuring. They are screwed directly into the component and are available with various thread sizes. The screw-in length of the PWF 73 is 19 mm. The plane measure surface of Ø 3.8 x 8 mm is followed by an 11 mm long M5 thread. The total length of the sensor is 38 mm with a key size of 10 mm for improved assembly on the end. Standard leads are galvanized copper wires with PFA- and fiberglass insulation covered by fiberglass and steel metal braid.
