Description
Technical field
The present invention relates to pressure transmitter research field, it can complete to test conduit in particular it relates to which one kind need not be removed
The pressure transmitter of cleaning.
Background technology
Pressure transmitter is a kind of to convert pressure into pneumatic signal or electromotive signal is controlled equipment with teletransmission.
The physical pressure parameters such as gas, the liquid that it can experience load cell are transformed into the electric signal of standard
(such as 4~20mADC), is measured with supplying the secondary meters such as indicator alarm, recorder, adjuster, indicated and process tune
Section.
Pressure transmitter is the most commonly used a kind of sensor in industrial practice, and it is widely used in various industrial automatic control rings
Border, be related to water conservancy and hydropower, railway traffic, intelligent building, production automatic control, Aero-Space, military project, petrochemical industry, oil well, electric power, ship,
Numerous industries such as lathe, pipeline.
Pressure transmitter has electrodynamic type and the major class of pneumatic type two.DYN dynamic unified output signal be 0~10mA, 4~
The DC signals such as 20mA or 1~5V.The unified output signal of pneumatic type is 20~100Pa gas pressure.
Pressure transmitter by different transfer principles can be divided into power (torque) balanced type, condenser type, inductance type, strain-type and
Frequency type etc., following is a brief introduction of the principle of several pressure (differential pressure) transmitter, structure, using knowledge such as, maintenance and verifications.
Pressure signal is passed to electronic equipment by the main function of pressure transmitter, and then in its principle of Computer display pressure
Generally:The mechanical signal of this pressure of hydraulic pressure is transformed into electronic signal pressure and voltage or electricity as electric current (4-20mA)
Flow size linear, usually proportional relation.So, transmitter output voltage or electric current with pressure increase and increase by
This show that two kinds of pressure of the measured medium of the relational expression pressure transmitter of a pressure and voltage or electric current are passed through high and low two pressure
Power room, low pressure chamber pressure uses atmospheric pressure or vacuum, on the both sides isolation diaphragm for acting on δ first (i.e. sensing element), by every
Measuring diaphragm both sides are sent to from the filling liquid in piece and element.
Electrode of the pressure transmitter on measuring diaphragm and both sides insulating trip respectively constitutes a capacitor.Work as pressure at both sides
When inconsistent, measuring diaphragm is caused to produce displacement, its displacement and pressure differential are directly proportional, therefore both sides capacitance is just, passes through
Vibration and demodulation link.
Pressure transmitter experiences the electric elements generally resistance strain gage of pressure, and resistance strain gage is a kind of by measured piece
On pressure conversion turn into a kind of Sensitive Apparatus of electric signal.It is at most metal resistance strain gauge and half that resistance strain gage, which is applied,
Two kinds of conductor foil gauge.Metal resistance strain gauge has two kinds of thread foil gauge and metal foil-like foil gauge again.Typically will strain
Piece is closely bonded in generation mechanics by special binder and strained on matrix, when stress variation occurs for matrix stress, electricity
Resistance foil gauge also produces deformation together, the resistance of foil gauge is changed, is changed so that being added in ohmically voltage.
Pressure transmitter is operationally to be connected through a screw thread to be fixed on test pipeline, by test conduit insertion testing tube
Tested, but tested long afterwards in road, the dregs in test pipeline are easily deposited in test conduit, cause to block, and then
Cause test inaccurate, it is therefore desirable to periodically to be cleaned, existing cleaning way is to remove to be cleaned and then loaded onto, a side
Face picks and places inconvenience, and cleaning efficiency is relatively low, and thread abrasion can be caused by the other hand repeatedly removing and then installing again, cause leakage to press
Leakage causes test inaccurate.
In summary, present inventor has found above-mentioned technology extremely during the present application technical scheme is realized
