Abstract
The sensor unit of the material tester consists of a pressure-sensor unit that measures a vertical force applied to the test probe during movement of the test probe relative to the test specimen and a horizontal force sensor unit for measuring the horizontally directed friction force. The horizontal force sensor unit is made in the form of a flexible parallelogram consisting of two sensor-holding plates interconnected through flexible beams, wherein one end of the first beam is attached to the upper sensor-holding plate and the opposite end to the lower sensor-holding plate, while one end of the second beam is attached to the lower sensor-holding plate and the other to the upper one. The beams are installed with gaps relative to both plates. The quick-release test probe incorporates a soft-touch feature.
