Description
Technical field
This utility model relates to protector for sensor field, a kind of corrosion-resistant sensor housing.
Background technology
The most perfect along with sensor technology, its application has been no longer limited to general environment occasion, the measurement work of the adverse circumstances such as high temperature, high humidity, salt fog, relys more on the properly functioning of sensor.Therefore, under harsh environments, it is necessary to be effectively protected sensor, guarantee sensor is accurate, stable operation.
Existing sensor housing, many employing die casting aluminiums are made.In the presence of a harsh environment, die-cast aluminium shell arises that extremely serious corrosion in a short period of time, jeopardizes normal, safety, the longtime running of sensor.And existing sensor housing lacks safety Design, it is not suitable for hazardous area.
Utility model content
This utility model provides a kind of corrosion-resistant sensor housing, to solve the problems referred to above.Being connected of sensing element housing, conversion element housing and the cable entry made by corrosion-resistant metal materials, provides airtight protection environment for sensor, it is ensured that sensor accurately, stable operation.Meanwhile, the connection of each inter-module, meet the national standard design requirement to explosion-insulation surface, it is ensured that sensor is at hazardous area safety, longtime running.
In order to realize the purpose of this utility model, plan employing techniques below:
A kind of corrosion-resistant sensor housing, it is characterized in that, including sensing element housing, conversion element housing and cable entry, the screw-internal thread fit that the external screw thread that described sensing element housing is arranged by one end is arranged with described conversion element shell one end is connected, the other end of described conversion element housing is provided with case lid, lower wall is provided with flame proof connecting screwed tube, and described flame proof connecting screwed tube is connected with described cable entry.
Further, described sensing element housing laminating sensor sensing member outboard is arranged, and arranges outside described conversion element housing laminating sensor conversion element.
Further, described case lid is connected with described conversion element housing seal by sealing ring.
Further, described sensing element housing, described conversion element housing and described cable entry all use corrosion-resistant metal materials.
Further, described sealing ring uses Erosion-Resisting Non-metallic Materials.
The beneficial effects of the utility model are:
1. being connected of sensing element housing, conversion element housing and the cable entry made by corrosion-resistant metal materials, provides airtight protection environment for sensor, it is ensured that sensor is accurate, stable operation.
The connection of the most each inter-module, meets the national standard design requirement to explosion-insulation surface, it is ensured that sensor is at hazardous area safety, longtime running.
Accompanying drawing explanation
Fig. 1 shows structural representation of the present utility model.
Detailed description of the invention
As it is shown in figure 1, a kind of corrosion-resistant sensor housing, including sensing element housing 1, conversion element housing 2 and cable entry 3.
The screw-internal thread fit that the external screw thread that described sensing element housing 1 is arranged by one end is arranged with described conversion element housing 2 one end is connected.It is easy to assemble, and meets the national standard design requirement to explosion-insulation surface.
The other end of described conversion element housing 2 is tightly connected with case lid 21 by sealing ring 4.Advantageously ensure that enclosure interior air-tightness.
Lower wall is provided with flame proof connecting screwed tube 22, and described flame proof connecting screwed tube 22 is connected with described cable entry 3.It is easy to assemble, and meets the national standard design requirement to explosion-insulation surface.
Described sensing element housing 1 is fitted and is arranged outside sensor sensing element 7, and described conversion element housing 2 is fitted and arranged outside sensor conversion element 8.Be conducive to stability sensor position in housing.
Described sensing element housing 1, described conversion element housing 2 and described cable entry 3 all use corrosion-resistant metal materials；Described sealing ring 4 uses Erosion-Resisting Non-metallic Materials.Advantageously ensure that sensor long-term stable operation under corrosivity adverse circumstances.
This utility model detailed description of the invention is as follows:
Described sensor sensing element 7 is carried female one end through described conversion element housing 2, makes described sensor conversion element 8 and described conversion element housing 2 inside fit.Described sensing element housing 1 is covered in outside described sensor sensing element 7, and is screwed by the screw-internal thread fit of the external screw thread of described sensing element housing 1 with described conversion element housing 2, complete to connect.
Described sealing ring 4 is placed between described case lid 21 and described conversion element housing 2, stoppers described case lid 21.I.e. complete housing body to assemble.
Cable is penetrated in described cable entry 3, screw in described flame proof connecting screwed tube 22, i.e. complete assembling and the protection of sensor.
This utility model, under marine environment and corrosive atmosphere, has carried out testing for many years, obvious corrosion phenomenon has not occurred.Thus solve the adverse circumstances etching problem to sensor housing, protection greatly and the service life of prolongation sensor.
