Detailed description of the invention
Below in conjunction with Figure of description, this utility model is described in further detail, and provides detailed description of the invention.
As Figure 1-3, this utility model one pressure transducer, it is provided with lower house 1 and upper shell 2, lower house 1 sets
Be equipped with interface thread, interface thread and upper shell 2 with the use of, lower house 1 is internal is provided with pressure sensing channel 3, pressure detecting
Circuit board 4, pressure detection circuit plate 4 is provided with lead-out wire, and pressure detection circuit plate 4 is by first circuit board and second circuit board
Composition, is connected by corrosion-resistant layers of two-sided between first circuit board and second circuit board, being provided centrally with of first circuit board
Glue filling opening, this double-layer circuit board, use glue filling opening encapsulation process.Also set up between pressure detection circuit plate 4 and lower house 1 inwall
Having silica gel pad 5, upper shell 2 is respectively arranged with interior rubber case 6 and outer rubber case 7 away from one end of lower house 1, for convenience of peace
Dress, the outward flange at pressure detection circuit plate 4 is symmetrically arranged with the first edge 8 and is symmetrical arranged at the outward flange of silica gel pad 5
There is the second edge 9.
This utility model is by using double-layer circuit board sealing water-proofing treatment, to improve corrosion resistance, interior high temperature, wear-resistant
Damage, anti shock and vibration, can use at a temperature of-40 DEG C～+150 DEG C, not affected by strenuous vibration；Meanwhile, wiring board is carried out
Thickening processes, and glue sealing board perforate stress accurately calculates, and the life-span is long, after using double-layered circuit board, can detect equipment pressure for a long time.Line
Road plate perforate encapsulating, sheet material is unlikely to deform, can life-time service,
Utility model works principle, pressure is communicated with pressure detection chamber and pressure inductor by pressure sensing channel,
Pressure signal is converted into the signal of telecommunication by operation principle and the circuit design of wiring board according to pressure transducer, passes through external lead wire
Power and gather the signal of telecommunication of generation, thus by pressure detecting out.
Above disclosed only this utility model preferred embodiment, can not limit this utility model with this certainly
Interest field, the equivalent variations therefore made according to this utility model claim, still belong to the scope that this utility model is contained.
