Problems solved by technology

At this time, the traditional displacement sensor and force sensor must be used in combination to meet the requirements of on-site engineering. In this way, several problems must be solved. One is that it is difficult to place two sets of sensors at the same time due to the influence of the test point equipment space, and the other is that the same test point must be solved. If the force test point and the displacement test point are not in the same test position, a certain error will occur

Abstract

The invention relates to a displacement and force test integrated sensor, comprising a force sensor, wherein the force sensor is in connection or contact with a tested member; the upper end of the force sensor is connected with a guide post through a guide sleeve; the upper surface of the guide post is connected with an upper end cover; a working spring is arranged between the upper end cover and the guide sleeve, and is used for transmitting force or displacement caused when the working spring is compressed, and working force when the guide post contacts a base of the guide sleeve to the force sensor. According to the displacement and force test integrated sensor, by using the unique structure test principle of the sensor, displacement is combined with the force sensor, so that force and displacement can be detected reliably, conveniently and accurately at the same time and the same point.

Description

technical field [0001] The invention relates to a sensor, in particular to a sensor integrating displacement and force testing. Background technique [0002] Displacement sensors and force sensors are the most common sensors in mechanical engineering, and they have a wide range of applications. These two sensors are used in most mechanical engineering control technologies. Some may be used alone and some need to be used together. There are also some special application requirements in actual engineering, such as the simultaneous detection of the working load and working displacement at a certain working point, such as the working load and working displacement of a working cylinder in a certain equipment. At this time, the traditional displacement sensor and force sensor must be used in combination to meet the requirements of on-site engineering. In this way, several problems must be solved. One is that it is difficult to place two sets of sensors at the same time due to the...
