Abstract

The invention discloses a contact type displacement sensor measuring device. Including: measurement part and data conversion part, the measurement part includes a housing, the connection part on the top of the housing is detachably connected to the data conversion part; the connection part is provided with a support arm, extending to the bottom of the housing; the sensor and the data conversion part in the housing electrical connection; the first end of the sensor is fixed on the measuring pen, and the second end lower than the first end is fixed on the support arm; the end of the measuring pen movable up and down in the housing is provided with a probe protruding from the bottom surface of the housing, and When the object under test moves relative to each other, the measuring pen is pushed upwards, the first end is far away from the second end, and strain is generated, and the data conversion part completes the measurement. The invention also discloses a measuring circuit of a contact displacement sensor. The invention uses a detachable structure adapted to the flexible strain sensor for measurement, improves system flexibility, original signal sensitivity and measurement accuracy, reduces circuit complexity, and has the advantages of simple structure and fast measurement.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to a contact displacement sensor measuring device and a measuring circuit. Background technique [0002] The contact displacement sensor measuring device is a commonly used size measuring sensor in the industry. It is often used in conjunction with three-coordinate measuring instruments and other equipment. It is an indispensable measuring equipment in modern production. Traditional contact displacement sensor measurement devices are usually measured by technical solutions such as mechanical type, differential transformer type, and grating ruler. [0003] For example, Chinese patent document CN1108384A discloses "contact displacement sensor measuring device for contour measurement", and Chinese patent document CN107003118A discloses "displacement sensor, displacement detection device and displacement detection method". The two patent documents use a grating ruler to measure displace...
