Magnetoelectric sensor principle, performance and characteristics are introduced
Magnetoelectric sensor is a kind of high cost performance, its performance is not easily affected by dust and condensation;
Its simple and compact structure, non-contact, long life, high and low temperature resistance, resistance to vibration, fast response speed, low cost.
Can be used to measure the speed, distance, Angle and displacement sensors.
Magnetoelectric induction magnetoelectric speed sensor is used to measure the rotational speed of the object, belongs to the non-contact speed measuring instrument.
Magnetoelectric speed sensor can be used for the surface of the object of aperture of speed measurement, has a good anti-jamming performance, in which devices such as engine speed monitoring, there are more applications in the industrial production.
Working principle of the magnetoelectric speed sensor of magnetoelectric speed sensor based on magnetoelectricity induction as the basic principle to realize the speed measurement.
Magnetoelectric speed sensor is composed of iron core, magnetic steel, induction coil and other parts of measured object turns, speed sensor coil produces the magnetic field lines, gears will cut lines of magnetic force, magnetic circuit due to magnetic resistance changes, within the induction coil produces electromotive force.
Induced potential of magnetoelectric speed sensor voltage size, and the object under test speed, the faster the speed of the object being measured the output voltage is, the greater the meaning that the output voltage is directly proportional to speed.
But in the speed of the object to be tested more than magnetoelectric speed sensor of measuring range, the magnetic circuit loss will be too big, make the output voltage satisfied even decline.
Magnetoelectric speed sensor is characteristic of magnetoelectric speed sensor works determines its strong anti-interference, in smoke, oil and gas, water vapor and other work environment.
Magnetoelectric speed sensor output signal is strong, wide measuring range, gear, crankshaft, spokes and other components, and there is crack on the surface of the rotating body can be measured.
The maintenance costs of magnetoelectric speed sensor is low, operation without power supply, is accomplished by magnetoelectric induction measurement, at the same time, the operation of magnetoelectric speed sensor does not need mechanical action, without lubrication.
Magnetoelectric speed sensor is of compact structure, small volume, convenient installation, can be used and various secondary instrument match.
Shanghai electronic research and development production of magnetoelectric sensor is widely used in robot, automatic production lines, automatic assembly machine, elevator, textile machinery, sewing machinery, packaging and printing machinery, CNC machine tools, mapper and Angle measuring instrument, etc.
Sensor also can be in PLC application as the high speed signal input element, make PLC more quickly and accurately implement the closed-loop control.
