Abstract

The invention discloses a processing method for a sensor copper shell. The processing method comprises the following steps of: S1: preparing a blank shell; S2: preparing a thick shell; S3: preparing a refined shell; S4: carrying out external surface treatment; and S5: carrying out anti-corrosion treatment, specifically, the interior the shell in the step S4 is subjected to sealing wax firstly; then zinc-nickel powder is smeared to the outer surface of the shell, a metal rod is inserted into the center of the wax, and then the shell is rotated; the zinc-nickel powder is heated by the high-temperature flame, so that the zinc-nickel powder is thermally molten to the outer surface of the shell; and an anti-corrosion layer on the outer surface is formed. The sensor shell provided by the invention is provided with the anti-corrosion layer externally, and the anti-corrosion layer is arranged on the outer wall of the sensor shell in a manner of hot melting, and the formed anti-corrosion layer has the anti-corrosion capability.

Description

technical field [0001] The invention relates to the technical field of sensor housings, in particular to a processing method for a sensor copper housing. Background technique [0002] The static pressure input liquid level sensor is suitable for liquid level measurement of various media in petrochemical, metallurgy, electric power, pharmaceutical, water supply and drainage, environmental protection and other systems and industries. The compact structure, simple adjustment and flexible installation provide convenience for users to use easily. Measuring liquid level using hydrostatic principles is an important application of pressure sensors. The use of a special cable with a ventilation duct in the middle and special sealing technology not only ensures the watertightness of the sensor, but also makes the reference pressure chamber communicate with the ambient pressure, thus ensuring the high precision and high stability of the measurement. [0003] The shell of the liquid l...
