Description
Technical field
The utility model relates to a kind of probe of the sensor that is used for liquid in the measuring channel, gas medium flow, is specifically related to a kind of capacitance probe of vortex flow sensors.
Background technology
Since vortex flow sensors comes out, because its range ability is wide, measurement lower limit is low, movable member simple in structure, no, do not have that machinery weares and teares, the pressure loss is little, production cost is low and more and more paid close attention to by people, but vortex flow sensors in the past adopts the piezoelectricity conversion regime more, because the technical indicator of piezoelectric element influence, make the temperature of measured medium be no more than 350 ℃, and anti-seismic performance is very poor; Existing capacitance probe all is that differential mode is worked, and fixed electrode all is to use stupalith and enclosure material stainless steel difference too big, causes shock resistance undesirable, and the manufacturing process complexity, and cost is very high, never popularization and application.
Summary of the invention
The purpose of this utility model is: a kind of capacitance probe of the vortex flow sensors that is used for liquid in the measuring channel, gas medium flow is provided, and simple in structure, with low cost, easy to use, stable operation, wide adaptability.
Above-mentioned purpose is to realize by following technical scheme: this capacitance probe comprises moving electrode, fixed electrode, seat ring and pressing plate, moving electrode at the bottom of seat ring mounting strap cavity, the top installation pressing plate of seat ring, be installed in fixed electrode in the moving electrode cavity by spacers on pressing plate, the tail end of moving electrode welding end socket.
In the capacitance probe of vortex flow sensors of the present utility model, the outlet of fixed electrode is installed in the sheath.
In the capacitance probe of vortex flow sensors of the present utility model, the fixed electrode of the capacitance probe of described vortex flow sensors and the gap between the moving electrode are 0.05～0.1mm.
This technical scheme has following beneficial effect:
1, this probe shock resistance is good, highly sensitive, and is steady in a long-term reliable, can measure 500 ℃ high temperature fluid.
2, do not have the rapid wear material, simple in structure, cost is low, and application prospect is good.
