Built-in displacement sensor

Abstract

The invention relates to the field of sensors, in particular to a built-in displacement sensor. The built-in displacement sensor comprises a protective shell, an inductive element, an installation assembly and a pressure-proof outer pipe; the installation assembly is arranged between the pressure-proof outer pipe and the protective shell; the left end of the protective shell is provided with a first flange, and the right end of the protective shell is provided with a second flange; the pressure-proof outer pipe is sleeved with a non-magnetic gasket which is in a disc shape; the left end of thenon-magnetic gasket is provided with a magnet which is in a cylindrical shape; the installation assembly comprises a connection ring sleeving the pressure-proof outer pipe, the connection ring is insliding fit with the pressure-proof outer pipe, and the outer side wall of the connection ring is provided with an installation thread; and the right end of the second flange is fixedly connected withthe left end of the connection ring. The built-in displacement sensor has the beneficial effects that when the built-in displacement sensor breaks down, a user loosens two hexagonal screws, thus, theinductive element can be pulled out, an oil cylinder does not need to be disassembled in the whole process, and great convenience is brought to the user.

Description

technical field [0001] The invention relates to the field of sensors, in particular to a built-in displacement sensor. Background technique [0002] Most of the traditional oil cylinders adopt the form of radial seal, so that the built-in displacement sensor is installed in the oil cylinder for measurement. When the displacement sensor has a problem, the entire oil cylinder must be disassembled to remove the sensor and replace the sensor. Then the oil cylinder can be used normally after being installed. The whole process is very time-consuming and the disassembly process is cumbersome, which brings a lot of trouble to the user. Contents of the invention [0003] The purpose of the present invention is to provide a built-in displacement sensor to solve the problems raised in the above-mentioned background technology. [0004] The technical solution of the present invention is to include a protective shell, an inductive element, a mounting assembly and a pressure-resistant ...

Problems solved by technology

[0002] Most of the traditional oil cylinders adopt the form of radial seal, so that the built-in displacement sensor is installed in the oil cylinder for measurement. When the displacement sensor has a problem, the entire oil cylinder must be disassembled to remove the sensor and replace the sensor. Then install the oil cylinder before it can be used normally. The whole process is very time-consuming and the disassembly process is cumbersome, which brings great trouble to the user.
