Background technology
Displacement transducer also known as linear transducer, for measuring the displacement of object of which movement.What current technical merit was in the world higher is the developed countries such as Germany, the U.S., and the product of these countries has high sensitivity, and technology content is also higher.But there is the problems such as maintenance difficulty is large, expensive when demestic user uses.Domestic displacement transducer manufacture level is limited, also there is certain problem during use.The metering system of current displacement transducer many employings contact type measurement, contact type measurement needs measuring media directly to contact with testee, there is the problem of self wearing and tearing or measuring error accumulation in Long-Time Service, needs often to change parts and maintenance, and measuring accuracy is also limited.
Utility model content
The technical problems to be solved in the utility model is to provide the non-contact displacement transducer that a kind of measuring accuracy is high, the life-span is long, applicability is strong.
The utility model non-contact displacement transducer, comprise magnet ring and the electronics storehouse with lead-out terminal, electronics is provided with wiring board in storehouse, wiring board is provided with the signal emission module for sending current pulse signal, for detecting the detection module of strain mechanical pulsing signal, strain mechanical pulsing signal is changed into modular converter and the signal processing module of displacement electric signal, for the output module of output displacement electric signal, wherein the output terminal of detection module is connected with the input end of modular converter, the output terminal of modular converter is connected with the discrepancy end of signal processing module, the output terminal of signal processing module is connected with the input end of output module, the output terminal of output module is connected with lead-out terminal, electronics storehouse is connected with sounding rod one end, the other end of sounding rod is closed, sounding rod inside is provided with waveguide filament along its length, waveguide filament is connected with the output terminal of the current output module in electronics storehouse, magnet ring internal diameter is greater than sounding rod external diameter, magnet ring surface working has connecting hole.
The utility model non-contact displacement transducer, the wherein said sounding rod arranged outside near side, electronics storehouse has connecting thread.
The utility model non-contact displacement transducer, wherein said waveguide filament selects magnetostriction materials.
The utility model non-contact displacement transducer difference from prior art is that the utility model non-contact displacement transducer adopts non-contact measurement, magnetostrictive effect between the second magnetic field utilizing the magnetic patch outside the first magnetic field of the rear generation of the energising of the waveguide filament in sounding rod and sounding rod to have makes waveguide filament produce one and strains mechanical pulsing signal, strain mechanical pulsing signal is delivered to modular converter after this strain mechanical pulsing signal being detected by detection module, modular converter and signal processing module convert strain mechanical pulsing signal to electric signal, and exported by output module.The signal that this device exports is the actual value of the ohject displacement converted by strain mechanical pulsing signal, instead of signal that is proportional or that amplify process, so there is not the situation of signal drift or variate, more without the need to regularly again demarcating zero point and scale.Easily there is the link of error when present arrangement avoids measurement, improve measuring accuracy.All the time be positioned at closed sounding rod as the waveguide filament of measuring media in whole measuring process, not with extraneous contact, therefore this device can carry out surveying work under comparatively severe working environment, and applicability is stronger.Simultaneously waveguide filament not with extraneous contact, do not have any wearing and tearing and consumption yet, the maintenance in later stage and the operation of renewal part can be saved, the serviceable life of extension device.
Below in conjunction with accompanying drawing, non-contact displacement transducer of the present utility model is described further.
