Background technology
High-temperature fusant pressure transducer is mainly used in pressure survey and the control of melt substance under hot conditions.High-temperature fusant pressure transducer is widely used in pressure survey and the control of the high temperature fluid medium of the equipment such as chemical fibre plastics, spinning, polyester, rubber and plastics machine.The principle of work of high-temperature fusant pressure transducer is that the pressure of medium acts directly on the diaphragm of sensor, diaphragm is made to produce the micrometric displacement be directly proportional to pressure medium, the resistance of sensor changed and uses this change of electronics wireline inspection, and changing the standard signal that output one corresponds to this pressure.
Inventor of the present utility model finds, high-temperature melt pressure transmitter of the prior art is all adopt between isolation diaphragm and pressure responsive element to connect with kapillary, and vacuumize in kapillary and fill this extremely toxic substance of mercury, because the accuracy measuring pressure will be ensured, the thickness of isolation diaphragm only has 0.12 mm of thickness, isolation diaphragm extremely easily breaks, thus causes mercury to leak, and causes heavy metal pollution.
Utility model content
The technical problems to be solved in the utility model is, provides a kind of environmental protection, there is not mercury and leaks, cause the high-temperature fusant pressure transducer without Filled Dielectrics of the potential safety hazard of heavy metal pollution.
For solving the problems of the technologies described above, the technical scheme that the utility model provides is: a kind of high-temperature fusant pressure transducer without Filled Dielectrics, and it comprises isolation diaphragm, capacitor plate, screw rod, shell and integrated circuit modules; Described capacitor plate comprises movable polar plate and fixed polar plate two parts; The upper end signal be provided with for being sensed by capacitor plate of described shell converts the integrated circuit modules of digital signal to, the lower end of described shell is connected with stainless-steel tube, wire is installed with in steel pipe, the end of stainless-steel tube is connected with screw rod, fixed polar plate is installed between stainless-steel tube and screw rod, and the lower end of described screw rod is provided with isolation diaphragm; Described movable polar plate is installed in the inner chamber of isolation diaphragm; Described capacitor plate is electrically connected with integrated circuit modules by wire.
As preferably, the thickness of described isolation diaphragm is greater than 0.12 millimeter.
After adopting said structure, the utility model has following beneficial effect: it comprises isolation diaphragm, capacitor plate, screw rod, shell and integrated circuit modules; Described capacitor plate comprises movable polar plate and fixed polar plate two parts; The upper end signal be provided with for being sensed by capacitor plate of described shell converts the integrated circuit modules of digital signal to, the lower end of described shell is connected with stainless-steel tube, wire is installed with in steel pipe, the end of stainless-steel tube is connected with screw rod, fixed polar plate is installed between stainless-steel tube and screw rod, and the lower end of described screw rod is provided with isolation diaphragm; Described movable polar plate is installed in the inner chamber of isolation diaphragm; Described capacitor plate is electrically connected with integrated circuit modules by wire.This practicality, by electric capacity pole plate is directly installed to isolation diaphragm inner chamber, by the distortion that isolation diaphragm is small, causes the electric capacity formed with fixed polar plate to change, is converted to simulating signal by integrated circuit, thus measures pressure.Adopt capacitance technology, accomplish innerly to belong to Green Product without any Filled Dielectrics completely, its isolation diaphragm adopts thick film technology, exceeds 4 times, without any leakage pollution hidden danger than traditional high-temperature melt pressure transmitter life-span.
In sum, this practicality provides a kind of environmental protection, there is not mercury and leaks, cause the high-temperature fusant pressure transducer without Filled Dielectrics of the potential safety hazard of heavy metal pollution.
