FIG. 1: the embodiment of the utility model provides a spatial structure schematic diagram.
FIG. 2 is a schematic diagram: the embodiment of the utility model provides a main structure schematic view.
FIG. 3: the embodiment of the utility model provides a section structure schematic diagram.
In the figure: the cable connector comprises a wiring terminal 1, a stainless steel base 2, a lower sealing ring 3, a stainless steel packing piece A4, an upper sealing ring 5, a stainless steel packing piece B6, an insulating layer 7 and a cable core wire 8.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The utility model provides an electrode extraction device of capacitanc sensor, please refer to the description attached drawing, including binding post 1, stainless steel base 2, lower seal ring 3, stainless steel packing piece A4, go up sealing washer 5, stainless steel packing piece B6, insulating layer 7, cable conductor 8, binding post 1 is connected with the one end of cable conductor 8, the outside cladding of cable conductor 8 has insulating layer 7, the stainless steel base 2, lower seal ring 3, stainless steel packing piece A4, go up sealing washer 5, stainless steel packing piece B6 have begun to connect gradually in the insulating layer 7 outside from binding post 1 one end. And threads are arranged on one side, close to the wiring terminal, of the outer part of the stainless steel base 2. The lower sealing ring, the upper sealing ring and the insulating layer are all made of polytetrafluoroethylene materials.
The first embodiment is as follows:
this device adopts stainless steel material cable conductor 8, and lower sealing washer, upper seal circle, insulating layer all adopt the polytetrafluoroethylene material. When the device is used, one end of the device is fixed on a pressure container through threads on a stainless steel base 2, a wiring terminal 1 in the device is connected with a capacitive sensor in the pressure container through a cable, and the other end of the device is connected with an external instrument through a cable core wire 8. The outside cladding insulating layer 7 of cable conductor 8, through stainless steel packing piece A, stainless steel packing piece B and the extrusion of stainless steel base 2, make lower sealing washer 3 and upper seal ring 5 receive extrusion deformation, act on the cable conductor 8 at center with the extrusion force on, thereby the realization is isolated with pressure in the pressure vessel with external, capacitive sensor signal can transmit through the cable conductor 8 at center, but atmospheric pressure then can not be from hereon transmitted, and then make the pressure vessel can realize accurate level measurement.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
