Abstract
The utility model belongs to a hall turbine flow transducer, which comprises a hall component as a core and is assisted by the regulation of a circuit and a magnetic circuit. The utility model is characterized in that a housing of an amplifier is matched with the upper end of the casing of a turbine flowmeter, one end of the casing of the amplifier is provided with a hall switch component, which is positioned at the bottom part of the umbilical eye of the casing of the turbine flowmeter; the upper part of the hall switch component is provided with a magnetic steel whose distance is adjustable, and one end of the magnetic steel is tightly matched with an adjusting rod; a turbine flowmeter impeller is arranged in the casing of the turbine flowmeter, the magnetic flow passing through the hall switch is changed, conduction and cut-off occur, and a pulse which has a synchronous pulse of an impeller revolution is sent out.
Description
The utility model relates to the prime amplifier of turbo flow meter, be specifically a kind of be core with the Hall switch element, be aided with the Hall flow sensor that circuit and magnetic circuit are regulated.
Turbo flow meter all adopts magnetic field, coil-induced mode to send flow signal at present, and there is the sender weak output signal in this type of mode, and unstable, and reliability is relatively poor, has influenced the operate as normal of turbo flow meter.
The purpose of this utility model provides a kind of magnetic field of using always, coil-induced sender mode do not taked, adopt the Hall switch element to be equipped with ball bearing made using and magnetic circuit adjusting, has output pulse amplitude near operating voltage, the sender signal is strong, stability and good reliability, load capacity is strong, a kind of turbine flow transducer suddenly that frequency response and anti-interference are good.
For finishing the technical scheme that above-mentioned purpose is taked: the amplifier housing is matched with the upper end of turbo flow meter housing, amplifier housing one end is established your on-off element, and be positioned at the navel eyeground portion of turbo flow meter housing, the top of Hall switch element is provided with the magnet steel of adjustable distance, magnet steel one end wringing fit adjuster bar, establish the turbo flow meter impeller in the turbo flow meter housing, because the magnetic conductivity of impeller, change magnetic flux by the Hall switch element, the conducting therefrom of Hall switch element, end conducting, end, go round and begin again, just send the pulse synchronous, after processing of circuit, just export a succession of pulse with wheel speed.For the turbo flow meter of different bores, as long as the distance between fine tuning magnet steel and the Hall switch element all can be sent stable pulse.
The utility model embodiment is described in detail in conjunction with the accompanying drawings.
Fig. 1 is the utility model structural drawing.
According to shown in Figure 1, amplifier housing 1 is matched with the upper end of turbo flow meter housing 9, amplifier housing 1 one ends are established Hall switch element 7 and are positioned at the navel eyeground portion of turbo flow meter housing 9, Hall element wiring board 5 is by epoxy resin 6 encapsulation, drawing three lead-in wires 2 simultaneously is connected with the existing signal amplifying circuit of wiping away in the art, the top of above-mentioned Hall switch element 7 is provided with the magnet steel 4 of adjustable distance, magnet steel 4 one ends tightly fit in adjuster bar 3, be used to regulate the distance between magnet steel 4 and the Hall switch element 7, use with the turbo flow meter that is fit to different bores, establish gib screw 10 in a side of adjuster bar 3.Establish turbo flow meter impeller 8 in the turbo flow meter housing 9.
The utility model adopts the Hall switch element, without coiling, only regulates with simple circuit and magnetic circuit, has realized pulse height near operating voltage, and load capacity is strong, the traffic pulse that frequency response and anti-interference are good.
