Abstract

The invention discloses a soil pressure sensor which comprises elements such as a push plate. The push plate is connected with a probe through a first O-shaped ring, a diffusion silicon core and a pressure cap are arranged in the probe, a second O-shaped ring is arranged on the outer periphery of the probe, and a circuit compensating plate is fixed with the pressure cap through a first screw and a first retainer ring. One end of a silicon rubber connection wire is connected with the circuit compensating plate while the other end of the silicon rubber connection wire is connected with an amplifying circuit. A shell is welded with the probe, the amplifying circuit is fixed to a pressure wire upper cover through a second retainer ring and a second screw, a sealing gasket is arranged between the pressure wire upper cover and the wire, a washer is arranged between the sealing gasket and a pressure wire nut, a third screw is fixed onto the pressure wire upper cover, and a steel ball is arranged in the probe and close to one side of the push plate. Elements such as the screws, the pressure wire nut and the pressure wire upper cover can be taken down for data adjustment.

Description

technical field [0001] The invention relates to a sensor, in particular to an earth pressure sensor. Background technique [0002] The existing sensors are all internally adjusted once they are moved, that is, after the data is set, no adjustment will be made. If the data needs to be adjusted, it will not be completed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an earth pressure sensor, which can adjust data by removing components such as screws, crimping nuts, and crimping caps as required. [0004] In order to solve the technical problem, the present invention provides an earth pressure sensor, which is characterized in that it includes a push plate, a first O-ring, a probe, a diffused silicon core, a compression cap, a second O-ring, a first One screw, first retaining ring, circuit compensation board, silicone rubber connecting wire, shell, amplifying circuit board, second retaining ring, second screw, c...
