1, sensor of vibration of type of electric vortex flow

 

Sensor of vibration of type of electric vortex flow is the oscillatory type sensor that eddy current effect is working principle, it belongs to blame contact sensor. Sensor of vibration of type of electric vortex flow is to pass the upright ministry of sensor and the span of the object that be measured to leave the change that go up, will measure object vibration parameter. Sensor of vibration of type of electric vortex flow basically uses what Yu Zhen moves displacement to measure.

 

2, sensor of inductance type vibration

 

Sensor of inductance type vibration is the sensor of a kind of vibration that designs according to electromagnetism induction principle. Sensor setting has inductance type vibration magnet and guide magnetic body, when undertaking to the object vibration is measured, can translate into of will mechanical oscillatory parameter electric parameter signal. Sensor of inductance type vibration can apply at the parameter such as oscillatory speed, acceleration measure.

 

 

3, sensor of capacitance type vibration

 

Sensor of capacitance type vibration is to pass the change of clearance or communal area to acquire alterable electric capacity, undertake determining to get mechanical and oscillatory parameter after that to capacitance again. Oscillatory sensor can divide capacitance type to be mixed for alterable clearance type type of alterable and communal area two kinds, former and OK with will measure linear and oscillatory displacement, latter can be used at turning round oscillatory angular displacement to determine.

 

4, sensor of vibration of the type that suppress report

 

The piezoelectric effect that uses crystal will finish vibration finish sensor of vibration of the type that suppress report to measure, when the vibration of the object that be measured oscillatory to pressing electric type sensor forms pressure hind, crystal component can generate corresponding charge, charge is counted can conversion is oscillatory parameter. Sensor of vibration of the type that suppress report still can be divided to press the sensor of electric type acceleration, type that suppress report force transducer is mixed impedance head.

 

5, sensor of vibration of resistance strain type

 

Sensor of vibration of resistance strain type is with resistor metabolic capacity conveys machinery of the object that be measured a kind of oscillatory sensor of oscillatory quantity. The implementation means of sensor of vibration of resistance strain type is very much, can apply all sorts of passing feeling component, among them relatively common is resistor meet an emergency.

 

 

What change requirement of level and high reliability as equipment intelligence is ceaseless rise, drive electric machinery is monitored in line position, the incline to of real time feedback of the position and rotate speed signal matchs for mark, the application of the electric machinery additional device such as switch of coder, overspeed, PT00, PTC, oscillatory sensor is more and more general. Understand these additional device, realize the organic confluence with electric machinery, crucial to electric machinery manufacturer. Below nearby some year of very common oscillatory sensor on incoming telegram machine and everybody make a communication.

 

Oscillatory sensor is made in electric machinery and trial segment is applied most extensive is instrument of electric machinery vibration, almost manufacturer of production of each electric machinery can be used.

 

The lopsided, electric blemish that report of parameter of vibration of the electric machinery in process of accurate industry production gives machine device, fastener becomes loose and other is unusual phenomenon, caused oscillatory problem brings about precision to drop and bring safe hidden trouble.

 

To electric machinery of large equipment complement, the client often can deploy oscillatory sensor. General sensor and controller combination are used, be worth a setting through parameter demarcate, electric machinery power source can be cut off forcibly when unusual position, protect action to arriving since electric machinery and equipment.
