Abstract
The utility model discloses an air intake manifold temperature and pressure sensor, including apron, casing, terminal, circuit board, pressure chip and thermistor, be equipped with the interface that admits air on the casing, the preceding end screw thread connection of the interface that admits air has the flow direction to adjust to connect, the flow direction adjust on the outer wall that connects circumference evenly offered with six louver mouths of the thermistor matched with four boundaries of a piece of land or a construction site. Adjust the joint through the threaded connection flow direction on the interface that admits air, can set up the position of adjusting the louver mouth on connecting the outer wall in the flow direction through sharp screw displacement adjustment to the function that flow direction when thermistor is flowed through to the mist of realization in to air intake manifold was adjusted has avoided thermistor directly to expose in the mist flow direction to a certain extent, reduce thermistor suffer the mist pollute and the reduction to the response speed of temperature variation and the possibility of precision.
Description
Technical field
This utility model relates to sensor technical field, especially relates to a kind of MAT and pressure transducer.
Background technology
MAT and pressure transducer are to be combined by pressure transducer and temperature sensor to form, and are arranged in inlet manifold, for monitoring MAP and air themperature simultaneously.Electromotor, according to the air themperature in inlet manifold and pressure actual test data the influence factor considering other relevant parameters, calculates the actual charge state of electromotor, and then provides the fuel oil injection quantity delivered of desired proportions for electromotor.The MAT of prior art and pressure transducer generally offer breach at air inlet place, although so facilitating the air in inlet manifold to flow through the temperature sensor being arranged on air inlet place, but, in the middle of the flowing of the mixing gas making temperature sensor be directly exposed in inlet manifold, very easily polluted and reduced the response speed to variations in temperature and precision.
Utility model content
This utility model is for the deficiencies in the prior art, technical problem to be solved is to provide a kind of MAT and pressure transducer, the function of flow direction when its mixing gas having in scalable inlet manifold flows through temperature sensor, temperature sensor is avoided to be directly exposed in gaseous mixture direction of flow to a certain extent, the probability that minimizing temperature sensor suffers to mix the pollution of gas and reduces the response speed to variations in temperature and precision.
This utility model is to make above-mentioned technical problem be addressed by the following technical programs.
MAT and pressure transducer, including cover plate, housing, terminal, circuit board, pressure chip and critesistor, housing is provided with intake interface, the nose threads of intake interface is connected to the flow direction and regulates joint, flows to circumference on the outer wall regulating joint and uniformly offers four to six the ventilation windows matched with critesistor.
As preferably, the middle part of intake interface is interval with double sealing circle.As improvement, the sidewall of intake interface is provided with sealed groove, and sealing ring is embedded on described sealed groove.Sealing ring is preferably O type.
As preferably, flowing to the appearance profile regulating joint is straight tube shape, dolioform or truncated cone.
As preferably, cover plate and housing are integrated injection molding structure.
As preferably, critesistor is negative temperature coefficient thermistor.
As preferably, pressure chip with critesistor all together with welding circuit board.
As preferably, cover plate for sealing is buckled in the top of housing.
The beneficial effects of the utility model:
1. delicate structure is compact, durable practicality, and good reliability is assembled simple, adopts double sealing circle to realize the sealing function to air, possesses excellent sealing property.
2. on intake interface, it is threaded connection the flow direction regulates joint, the orientation flowing to the ventilation window regulated on joint outer wall can be opened in by straight-line helix adjustment of displacement, thus realizing the function that the flow direction when mixing gas in inlet manifold is flowed through critesistor regulates, avoid critesistor to a certain extent and be directly exposed in gaseous mixture direction of flow, reduce critesistor and suffer gaseous mixture body pollution to reduce the probability of the response speed to variations in temperature and precision.
Accompanying drawing explanation
Fig. 1 be this utility model in working order under structural representation.
In figure: 1-cover plate, 2-housing, 3-critesistor, 4-intake interface, 5-flows to and regulates joint, and 6-ventilates window, 7-sealing ring.
Detailed description of the invention
By the examples below and in conjunction with accompanying drawing this utility model is described in detail.
This utility model MAT as shown in Figure 1 and pressure transducer, including cover plate 1, housing 2, terminal, circuit board, pressure chip and critesistor 3, cover plate 1 and housing 2 preferably employ integrated injection molding structure, cover plate 1 sealed card is buckled in the top of housing 2, pressure chip is with critesistor 3 all together with welding circuit board, and critesistor 3 preferably employs negative temperature coefficient thermistor.Housing 2 is provided with intake interface 4, when being installed in inlet manifold, in order to keep good sealing property, the interval, middle part of intake interface 4 arranges double sealing circle 7, sealed groove can be set on the sidewall of intake interface 4, being embedded on described sealed groove by sealing ring 7, sealing ring 7 is preferably O type.The nose threads of intake interface 4 is connected to the flow direction and regulates joint 5, flow to circumference on the outer wall regulating joint 5 and uniformly offer four to six the ventilation windows 6 matched with critesistor 3, for the convenient flow direction regulating and mixing gas in inlet manifold, according to selecting needed for actual angle offer four, five or six ventilation windows 6, the angle adjustment carrying out ventilation window 6 when the appearance profile regulating joint 5 may be selected to be straight tube shape, dolioform or truncated cone can better coordinate and to flow to and regulate joint 5 straight-line helix displacement can be flowed to.
This utility model is not limited to above-described preferred implementation; the known technology that can know based on those skilled in the art or adopt is caned the various deformation of equivalence replacement and the embodiment of change in prior art; every conceive based on spirit of the present utility model or technology, should be included within protection domain of the present utility model.
