Abstract

The invention provides a force / torque measuring sensor which comprises an elastic base, a substrate and a full-bridge sensitive element, wherein the substrate is arranged on an elastomer to be utilized as a middle base, and the full-bridge sensitive element is arranged on the substrate to be used for detecting a twisting force value and a torque value of the elastic base in deformation and outputting detection results in a multi-channel mode. According to the force / torque measuring sensor disclosed by the invention, the ceramic substrate is arranged on the elastic base of the force / torque measuring sensor, the thick-film full-bridge sensitive element is arranged on the ceramic substrate to measure the twisting force and the torque; on one hand, the problems that the ceramic substrate has low elastic strength and large fragility are effectively overcome, and the sensor can be used under varieties of dynamic impact conditions; on the other hand, high-output-flexibility multi-parameter measurement and multi-channel transmission of the twisting force and the torque are achieved.

Description

technical field [0001] The present invention relates to the technical field of sensors, in particular to a force measuring / torque sensor. Background technique [0002] There are various ring load cells in China, and the structure of the sensitive element is resistance strain type, that is, a metal foil strain gauge or a semiconductor strain gauge is pasted on the metal elastic body to convert the elastic deformation of the elastic body into a resistance change after the elastic body is stressed. The bridge provides the output. This type of structure has the following disadvantages: the foil resistance strain gauge has low sensitivity, the size cannot be made too small, and the internal resistance is low, which cannot meet the requirements of low profile and micro power consumption; the semiconductor strain gauge, although small in size, can have high internal resistance and high sensitivity. High, used for materials that are sensitive to temperature and have a large tempera...
