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 81 mm is 85 mm. The ball sensor tube of Ø 7 x 70 mm is followed by a G 1/8” x 15 mm thread with a key size of 17 mm. The total sensor length is 95 mm. The passage of sensor to leads is conical strain relieved. An Ø 8 x 65 mm spring is used as anti-kink protection.
