Abstract
The invention discloses a novel pressure type pneumatic sensor. A corrugated pipe is adopted as a size conversion and amplification element, and comprises a first corrugated pipe and a second corrugated pipe, wherein one end of the first corrugated pipe and one end of the second corrugated pipe are fixedly arranged on the two inner sides of a frame, and the other ends of the first and second corrugated pipes are pneumatically and freely connected; an indicating gauge is arranged at one end of the frame; a detected element is arranged at the bottom end of an air pipeline pneumatically connected with the corrugated pipe. According to the novel pressure type pneumatic sensor, the corrugated pipe is adopted as the size conversion and amplification element, so that the novel pressure type pneumatic sensor is sensitive in detection, high in accuracy and precision, easy and convenient to operate and convenient to popularize and use.
Description
Technical field
The invention belongs to sensing detection technical field, relate to a kind of pneumatic transmitter, be specifically related to a kind of novel pressure formula pneumatic transmitter.
Background technology
Sensor is a kind of pick-up unit, measured information can be experienced, and the information that can will experience, the information being for conversion into electric signal or other desired forms according to certain rules exports, to meet the requirements such as the transmission of information, process, storage, display, record and control.The feature of sensor comprises: microminiaturization, digitizing, intellectuality, multifunction, systematization, networking.It is the primary link realizing automatically detecting and automatically controlling.The Existence and development of sensor, the sense organ such as sense of touch, taste and smell that allowed object have, allows object slowly become and has lived.
Usually the ten large classes such as thermal sensing element, light activated element, gas sensor, force sensing element, magneto sensor, humidity-sensitive element, acoustic sensor, radioactive ray sensitive element, color sensor and taste photosensitive elements are divided into according to its basic perceptional function.Wherein, the physical quantity such as pressure or flow, electricity and light intensity that tested length transition is air by pneumatic, principle and the photoelectric effect etc. such as electricity, optics is utilized, to obtain the measuring sensor of metrical information, in some dimensional measuring instrument.
Linear transducer is primarily of primary element and conversion element composition.Conversion element is accurately converted to the tested length that primary element is experienced other physical quantitys of being convenient to amplify and process.
Summary of the invention
Technical matters to be solved by this invention be to provide a kind of with low cost, easy to operate, detect sensitive novel pressure formula pneumatic transmitter.
For solving the problems of the technologies described above, a kind of novel pressure formula of the present invention pneumatic transmitter, adopt corrugated tube as size conversion and amplifier element, described corrugated tube comprises the first corrugated tube and the second corrugated tube, one end of first corrugated tube and the second corrugated tube is fixed on the both sides in framework, freely connected by pneumatic between the other end of the first corrugated tube and the second corrugated tube, one end of described framework is provided with indicating gauge, is placed in the bottom of the gas path pipe that be connected pneumatic with corrugated tube by side element.
On the basis of technique scheme, be also provided with balancing controls with on the pneumatic gas path pipe be connected of described corrugated tube.
The present invention also can arrange electric contact in one end of framework, and whether according to contact whether, it is qualified by Thickness Measurement by Microwave to be indicated by pilot lamp.
Compared with prior art, beneficial effect of the present invention is:
The present invention is with low cost, adopts corrugated tube as size conversion and amplifier element, and be that the pressure of air comes with the measuring sensor obtaining metrical information by tested length transition, detect sensitive, accuracy and precision is good, simple to operation, is convenient to promote the use of.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.

Embodiment
Embodiment 1
As shown in Figure 1, a kind of novel pressure formula pneumatic transmitter, adopt corrugated tube as size conversion and amplifier element, described corrugated tube comprises the first corrugated tube 1 and the second corrugated tube 2, one end of first corrugated tube 1 and the second corrugated tube 2 is fixed on the both sides in framework 2, freely connected by pneumatic between first corrugated tube 1 and the other end of the second corrugated tube 2, one end of described framework 2 is provided with indicating gauge 4, is placed in the bottom of the gas path pipe that be connected pneumatic with corrugated tube by side element 5.Balancing controls 6 are also provided with on the pneumatic gas path pipe be connected of described corrugated tube.
The present invention adopts corrugated tube as size conversion and amplifier element, gap S is caused to change by the variation in thickness of side element 5, S change causes again ripple overpressure to change, thus framework 2 is moved to the left or to the right, the distance of movement is exactly the tested variation in thickness be exaggerated, and is indicated by indicating gauge 4.
Embodiment 2
One end of described framework 2 is provided with electric contact 7, the bottom of the gas path pipe that be connected pneumatic with corrugated tube will be placed in by side element 5, gap S is caused to change by the variation in thickness of side element 5, S change causes again ripple overpressure to change, thus framework 2 is moved to the left or to the right, whether whether contact according to electric contact 7, it is qualified by Thickness Measurement by Microwave to be indicated by pilot lamp again.
