Description
Technical field
The present invention relates to relate to pressure unit, relate in particular to a kind of pressure unit that is exclusively used in inlet manifold of IC engine.
Background technology
Existing pressure unit is fixing variation ratio, can not regulate its range.And this pressure deflection machine that can not regulate range is not suitable for the pressure unit of inlet manifold of IC engine.
Summary of the invention
The present invention is directed to the above-mentioned defective of prior art, a kind of pressure unit that is exclusively used in inlet manifold of IC engine is provided, so that this deflection machine measuring range adjustable.
In order to solve the problems of the technologies described above, the present invention realizes through following technical scheme:
A kind of pressure unit; Comprise electronic-controlled installation and pressure transducer; Said pressure transducer is connected with electronic-controlled installation through signal wire, and electronic-controlled installation comprises signal processing chip, display module, and signal processing chip is connected with display module; Signal processing chip is provided with connection terminal, and this connection terminal is connected with pressure transducer through signal wire.

Can find out from above technical scheme; The present invention combines practical application to make the measuring range adjustable of transmitter; Measurement with the pressure that is suitable for inlet manifold of IC engine; And make the interior air-distributor pressure range of unit total power scope corresponding to 4～20mA, and balance each other so that in the auxiliary fuel supply-system of internal combustion engine generator group, become feed signals with electric power, accomplish the air-fuel ratio situation and differentiate.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
Embodiment
Below in conjunction with embodiment the present invention is done further detailed explanation.
The principle of work of pressure unit is: two kinds of pressure of measured medium feed high and low two pressure chambers, act on the both sides isolation diaphragm of δ element (being sensitive element), are sent to the measuring diaphragm both sides through the filling liquid in spacer and the element.Electrode on measuring diaphragm and the both sides insulating trip is respectively formed a capacitor.When pressure at both sides is inconsistent, cause measuring diaphragm to produce displacement, its displacement and pressure differential are directly proportional, so the both sides electric capacity does not just wait, through vibration and demodulation link, convert the signal that is directly proportional with pressure to.The principle of work of pressure unit and absolute pressure transducer is identical with differential pressure transmitter, and different is that low-pressure chamber pressure is atmospheric pressure or vacuum.
Pressure unit becomes digital signal through A/D converter with the current conversion of detuner, and its value is used for judging the input pressure value by microprocessor.The work of microprocessor control transmitter.In addition, it carry out linear sensorization.The replacement measurement range.Engineering unit conversion, damping, evolution, computings such as sensor fine setting, and diagnosis and digital communication.
Pressure unit 1 of the present invention; Comprise electronic-controlled installation and pressure transducer, said pressure transducer is connected with electronic-controlled installation through signal wire, and electronic-controlled installation comprises signal processing chip, display module; Signal processing chip is provided with connection terminal; This connection terminal is connected with pressure transducer through signal wire, and the detected pressure signal of processes sensor, is sent to display module after signal processing chip is handled pressure signal and shows.
As preferred implementation of the present invention, also comprise zeroing correction knob, this zeroing is proofreaied and correct knob and is connected with signal processing chip with zeroing.
Claims (2)
1. pressure unit; It is characterized in that: comprise electronic-controlled installation and pressure transducer; Said pressure transducer is connected with electronic-controlled installation through signal wire, and electronic-controlled installation comprises signal processing chip, display module, and signal processing chip is connected with display module; Signal processing chip is provided with connection terminal, and this connection terminal is connected with pressure transducer through signal wire.
2. pressure unit according to claim 1 is characterized in that: also comprise zeroing correction knob, this zeroing is proofreaied and correct knob and is connected with signal processing chip with zeroing.
