Device for measuring tension on textile-or technical yarn, has multiple power transmission bodies switched one behind other, probe movably stored on device, and piezo-resistive pressure sensor filled with liquid

摘要

The device has multiple power transmission bodies (11) switched one behind the other. A probe (9) is movably stored on the device. A piezo-resistive pressure sensor (13) e.g. absolute pressure sensor and relative pressure sensor, is filled with liquid (15). The probe is attached with lamella (10) that is formed as a flexible spring. The transmission bodies are made of an elastomer and attached at the probe. The transmission bodies are fastened to a diaphragm (12) of the pressure sensor with conical cross section in a direction of force to be transmitted.
