Description
Technical field
It the utility model is related to fluid inspection switching device technical field, and in particular to the stream that a kind of mechanical electronic dual-display shows
Body pressure or flow monitoring switching device.
Background technology
Nowadays, the pressure switch of fluid and flow monitoring are always the emphasis measured in industry.
Current fluid pressure switch is substantially segmented into electronic pressure switch and mechanical pressure switch.Wherein, machine
What tool formula pressure switch was leaned on is elastic deformation and the stroke of pressure element, pressure conversion into switching signal, not powered, with regard to energy
Complete switch motion.Conventional flexible member is helical spring, promotes piston to produce displacement by pressure differential, it is dynamic to complete switch
Make.Electronic pressure switch needs to power, by mv signals corresponding to pressure sensor acquisition pressure, the conversion through oversampling circuit,
Obtained on-off model.Because the continuous value of control circuit acquisition sensor, the pressure that can be gone out with real-time display in container,
Output switch amount signal is compared with setting value, function is relatively mechanical powerful many.Although mechanical pressure switch sound construction,
The abilities such as anti-strong magnetic, intense radiation are strong, but in general mechanical pressure switch can only play on-off action, can not accomplish fluid pressure
Power monitors and real-time display.It is powerful and electronic pressure switch is compact, but in general electronic pressure switch all can be by
The influence of the strong environment such as magnetic and intense radiation so that use occasion is limited.
Current rate of flow of fluid monitoring can be divided into mechanical impeller coder form monitoring, ultrasonic wave prison in operation principle
Survey, optical monitoring and rate of heat dissipation method etc..Wherein mechanical means measurement flow velocity is the anglec of rotation speed according to the impeller being placed in fluid
The principle directly proportional to the flow velocity of fluid is spent to carry out flow velocity measurement, and the rotating speed of impeller is measured by encoder, passes through monolithic
Electromechanical road carries out data processing and amendment.Blade wheel structure is complicated in tradition machinery formula, it is difficult to manufactures, foozle directly affects leaf
The output of rotary speed is taken turns, influences measurement accuracy.During ultrasound examination rate of flow of fluid, the ultrasonic wave of instrument transmitting is in water transmission
When, the Doppler frequency signal related to water velocity will be produced.The ultrasound frequency signal that sensor sensing transmitter is sent
And the reflection of test point suspended particulates and scattered wave signal, and they are delivered to receiver mixing.Then detected by demodulator more
General Le frequency signal, and it is amplified shaping.Controlled again by single-chip microcomputer and carry out data processing.During one-dimensional flow velocity measurement, sensing
Device must face flow direction.If deviateing some angle, institute's velocity measurement value is then actual flow velocity in the vertical component that this side up.Measure
Two orthogonal velocity components, then it can synthesize a new velocity vector.Here it is two-dimentional flow velocity measuring principle.This
Mode measurement range is wide, and use range is wide, but cost is higher.Optical monitoring flow velocity measures also with laser doppler
Flow velocity, cost are also very high.The principle of rate of heat dissipation method measurement flow velocity is that the tachogenerator of heating is placed in detected fluid, profit
With the rate of heat dissipation of the tachogenerator of heating it is proportional to rate of flow of fluid the characteristics of, obtained by the rate of heat dissipation of determination sensor
The flow velocity of fluid.In addition, rate of flow of fluid monitoring is concentrated mainly at present, and it is less for the device of flow rate switch.
In order to improve pressure switch or flow monitoring device under various circumstances, under particularly severe, particular surroundings, it is ensured that
Its functional reliability and adaptability, and the pressure detecting of device or the function of flow rate switch can be increased, we provide a kind of new
The Fluid pressure or flow monitoring switching device that the mechanical electronic dual-display of type shows.
