Description
Technical field
Pressure transmitter research field is the utility model is related to, in particular it relates to a kind of wireless Precision Pressure Transmitter fortune
Defeated apparatus for placing.
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 that load cell is experienced, liquid can be transformed into the electric signal of standard by it
(such as 4~20mADC), measured with supplying the secondary meters such as indicator alarm, recorder, adjuster, indicate and process adjust
Section.
Pressure transmitter is a kind of sensor the most commonly used 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., it following is a brief introduction of the knowledge such as the principle, structure, use, maintenance and verification of several pressure (differential pressure) transmitter.
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)
It is linear to flow size, 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 use atmospheric pressure or vacuum, act on the both sides isolation diaphragm of δ first (i.e. sensing element), by every
Measuring diaphragm both sides are sent to from the filling liquid in piece and element.
Pressure transmitter respectively forms a capacitor by the electrode on measuring diaphragm and both sides insulating trip.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 demodulating link.
The electric elements that pressure transmitter experiences pressure are generally resistance strain gage, 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 by special binder to be produced on mechanics strain 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 belongs to precision apparatus, its measuring diaphragm and resistance strain gage easily by less impact just
It can damage, therefore, in the prior art, pressure transmitter carried out to first have to the test of pressure transmitter during storage computing
The port of conduit carries out process seal, is then wrapped up layer by layer, is finally putting into storage chest, and deposits chest and set in advance
Put and be fixed with the groove of the matching of pressure transmitter size, such result causes the cost of storage higher, and different
The pressure transmitter of model needs different casings to be deposited, since it is desired that the form fit of groove.
