Anticorrosion sensor with sealed structure

Abstract

The invention discloses an anticorrosion sensor with a sealed structure. The anticorrosion sensor with the sealed structure comprises a measuring assembly with a shaft shoulder structure, and an anticorrosion vibrator lower sleeve, wherein the anticorrosion vibrator lower sleeve is connected to the position, arranged below the shaft shoulder structure, of the measuring assembly in a sleeved mode, the surface, corresponding to a shaft shoulder, of the anticorrosion vibrator lower sleeve serves as a sealing surface, a first sealing ring is arranged between the sealing surface of the anticorrosion vibrator lower sleeve and a sealing surface of the shaft shoulder, and an annular groove is formed in the sealing surface of the anticorrosion vibrator lower sleeve, and is used for containing the first sealing ring. According to the arrangement, the anticorrosion sensor with the sealed structure has the good sealing effect.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to an anti-corrosion sensor with a sealing structure. Background technique [0002] The guided wave radar level gauge is a radar level gauge based on the principle of reflection. Its working principle is that the electromagnetic pulse emitted by the radar level gauge propagates along the steel cable or probe at the speed of light. When it touches the surface of the measured medium When , part of the pulse of the radar level gauge is reflected to form an echo and returns to the pulse transmitting device along the same path. The distance between the pulse transmitting device of the radar level gauge and the surface of the measured medium is proportional to the propagation time of the pulse, so, The liquid level can be calculated according to the propagation time of the pulse. [0003] Guided wave radar level gauges have been widely used in chemical industry, coal, steel and other ind...

Problems solved by technology

[0006] However, since the surface of the measurement component 01 is relatively smooth, when the measurement component 01 and the lower sleeve 02 of the anti-corrosion vibrator are assembled to extrude the O-ring seal 03, the O-ring seal 03 is easily extruded out of the sealing mating surface along the measurement component 01 , the sealing effect cannot be achieved, which in turn causes the problem of poor sealing effect of the anti-corrosion sensor

[0007] Therefore, how to solve the problem of poor sealing effect of anti-corrosion sensors in the prior art has become an important technical problem to be solved by those skilled in the art
