Abstract
The utility model provides a high-pressure resisting pressure sensor which comprises a pressure sensitive element for measuring pressure, wherein an original body of the pressure sensitive element is connected with an amplifying conditioning circuit board through a signal lead; the amplifying conditioning circuit board is connected with an electric appliance plug through an internal connecting lead; the electric appliance plug is connected with an external connecting lead; the high-pressure resisting pressure sensor is characterized in that the pressure sensitive element is arranged in a pressure measuring connector and is fastened by a fixing nut; the amplifying conditioning circuit board is arranged in a sensor shell; and the sensor shell and the pressure measuring connector are formed into an integrated structure. Such a designed sensor shell is simple in structure and convenient in processing; some processes for processing the sensor shell are reduced; the overall dimension of the sensor shell is identical to that of the sensor shell before the design is improved; mounting and debugging are free from being influenced; and meanwhile, the new structure design is adopted, so that the thinnest part of a wall of the sensor is greatly thickened, the pressure resistance of the sensor is greatly increased and the high-pressure resisting pressure sensor is suitable for higher pressure measurement.
Description
Technical field
The utility model relates to the hydraulic system technical field, concrete relates to a kind of high voltage bearing pressure transducer that is used to measure hydraulic system pressure.
Background technology
Pressure transducer is a kind of sensor the most commonly used in the industrial practice; It is widely used in various industrial automatic control environment, relates to numerous industries such as water conservancy and hydropower, railway traffic, intelligent building, production automatic control, Aero-Space, military project, petrochemical industry, oil well, electric power, boats and ships, lathe, pipeline.Its major function is that the physical pressure amount with fluid to be measured or gas converts electric signal to and is transferred to distant place instrument or controller.
Like Fig. 1, Fig. 2 and shown in Figure 3, the pressure sensor structure of prior art generally comprises pressure measurement connector 1, pressure-sensing device 2, O-ring seal 3, hold-down nut 4, signal conductor 5, sensor outer housing 6, amplifying and conditioning circuit plate 7, internal connecting wire 8, appliance plug 9, the outside lead 10 that connects.
Pressure-sensing device 2 is embedded in the pressure measurement connector 1; And it is pressure-sensing device 2 is fixing with hold-down nut 4; Fluid to be measured or gas act directly on the pressure-sensing device 2; Pressure-sensing device 2 converts the physical pressure value of fluid to be measured or gas to faint voltage signal; This signal transfers in the amplifying and conditioning circuit plate 7 through signal conductor 5; Internal circuit through amplifying and conditioning circuit plate 7 changes into stronger voltage, electric current, frequency or the digital signal that distant place instrument can be discerned with the weak voltage signal that pressure-sensing device 2 produces, and the signal of handling through amplifying and conditioning circuit plate 7 is connected on the appliance plug 9 through internal connecting wire 8 again, connects lead through the convenient outside that plugs again at last final electric signal is transferred to distant place instrument or controller; Sensor outer housing 6 plays the effect of the inner precise electronic components and parts of protection, prevents that internal components from answering the external force effect and damage.
Wherein pressure measurement connector 1 should embedment pressure sensitive element 2; Install and fix nut 4 again; Also want sensor installation shell 6; Compact structure causes pressure measurement connector 1 part in compression to produce weak part (like A point, the B point of pointing out among Fig. 3) making the pressure measurement scope of whole pressure transducer be restricted, promptly can not use in the higher measured object pressure survey of pressure.
The utility model content
The utility model technical matters to be solved is, overcomes the problem that exists in the prior art, and a kind of high voltage bearing pressure transducer is provided.
For the technical scheme that addresses the above problem the utility model is such:
High voltage bearing pressure transducer comprises the pressure-sensing device that is used for pressure measurement, and the presser sensor original paper connects the amplifying and conditioning circuit plate through signal conductor; The amplifying and conditioning circuit plate is through internal connecting wire connecting circuit plug; Appliance plug connects the outside lead that connects, and it is characterized in that it is interior and fastening by a hold-down nut that pressure-sensing device is arranged on a pressure measurement connector; The amplifying and conditioning circuit plate is arranged in the sensor outer housing, and said sensor outer housing and pressure measurement connector are structure as a whole.
Be provided with the internal thread that an end is used to connect hold-down nut in the pressure measurement connector.
Beneficial effect, the design's sensor outer housing structure is simple, and is easy to process, reduced the part operation of processed sensor shell, identical before physical dimension and the design improvement, do not influence to install and debugging.Simultaneously,, improved the withstand voltage properties of sensor greatly, made it to use in higher pressure survey because the new structural design that adopts makes the wall thickness thinnest part of sensor significantly thicken.

Fig. 5 is the II place enlarged drawing of Fig. 4.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 4 and Fig. 5,
High voltage bearing pressure transducer; Comprise with pressure measurement connector 1, pressure-sensing device 2, O-ring seal 3, hold-down nut 4, signal conductor 5, sensor outer housing 6, amplifying and conditioning circuit plate 7, internal connecting wire 8, appliance plug 9, the outside lead 10 that connects; It is interior and fastening by hold-down nut 4 that pressure-sensing device 2 is arranged on pressure measurement connector 1; Amplifying and conditioning circuit plate 7 is arranged in the sensor outer housing 6, and said sensor outer housing 6 is structure as a whole with pressure measurement connector 1.Be provided with the internal thread that an end is used to connect hold-down nut 4 in the pressure measurement connector 1.
Under the situation that does not change the sensor external dimensions, strengthen the withstand voltage properties of sensor, make pressure transducer can use under the higher operating mode of pressure.
More than show and described the advantage of ultimate principle, principal character and the utility model of the utility model.The technician of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the instructions that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
