Detailed description of the invention
With detailed description of the invention, this utility model is described further below in conjunction with the accompanying drawings.
This utility model as shown in Figure 1 and Figure 2, rotary capacitor sensor, by lifting screw 1, piston 2, insulation dottle pin 3,
Right binding post 41, right electric capacity bar 42, right capacitance sheet 43, packing ring 5, cabinet 6, left binding post 71, left electric capacity bar 72, a left side
Capacitance sheet 73, nut 8, gas medium 9, liquid medium 10, O RunddichtringO 11 form.
Outside described lifting screw 1 is connected with piston 2 after the base plate bottom cabinet 6, and lifting screw 1 is with plastics
Shell 6 uses screw thread pair to connect, and rotates lifting screw 1, it is possible to achieve lifting screw 1 rises or falls, and then drives piston 2 with exhausted
Edge dottle pin 3 rises or falls, and can allow and move or move down on liquid medium 10, owing to right capacitance sheet 43 and left capacitance sheet 73 are that interval is worn
Insert and install, and leave gap between right capacitance sheet 43 and left capacitance sheet 73, the gap between right capacitance sheet 43 and left capacitance sheet 73 can be made
It is completely filled with liquid medium 10, or part fill liquid medium 10, or is fully populated with gas medium 9, it is achieved that capacitance size
Adjustable, it addition, when external environment situation changes, can in the internal gap between right capacitance sheet 43 and left capacitance sheet 73
Filling, to environment medium advantageously, reduces the environment impact on electric capacity, improves the precision of sensor.
Described piston 2 has been fitted around O RunddichtringO 11, and the internal chamber wall of O RunddichtringO 11 and cabinet 6 closely connects
Touching, O RunddichtringO 11 plays sealing function.
Described piston 2 is installed above insulation dottle pin 3, and insulation dottle pin 3 is made from an insulative material, can be piston 2 and right electricity
Hold sheet 43 to keep apart, it is to avoid piston 2 directly contacts with right capacitance sheet 43 and turns on.
