Problems solved by technology

However, when the current common speed measuring magnetic sensor is produced, the magnet shell is separated from the shell, which is not only inconvenient to connect and fix, but also the magnet shell is easy to loosen during use, and the magnet is easy to fall, thus causing the sensor to malfunction.

Abstract

Disclosed in the invention is a pressure sensor comprising a pressure sensor body formed by injection molding. A wide-range sensor and a small-range sensor are arranged inside the pressure sensor body; the wide-range sensor is connected with a protection sleeve; and the small-range sensor is connected with the protection sleeve. A plurality of copper connection posts are arranged between the wide-range sensor and the small-range sensor; and copper sheets connecting the wide-range sensor and the small-range sensor are arranged at the tops of the copper connection posts. According to the invention, the pressure sensor has advantages of convenient mounting and dismounting, flexible usage, and high measuring system reliability.

Description

technical field [0001] The invention relates to a pressure sensor, which belongs to the field of measurement and detection. Background technique [0002] A sensor is a detection device that can sense the measured information and convert the sensed information into electrical signals or other required forms of information output according to certain rules to meet the requirements of information transmission, processing, storage, and display. , recording and control requirements. There are many kinds of sensors, one of which is a magnetic sensor. When the signal rotor rotates clockwise, the gap between the rotor teeth and the magnet decreases, the reluctance of the magnetic circuit decreases, the magnetic flux increases, and the rotor teeth approach the edge of the magnet. When , the magnetic flux increases sharply, the rate of change of magnetic flux is the largest, and the induced electromotive force is the highest. However, when the current common speed measuring magnet...
