B. fluid passes through from the oil circuit of one of them sensor, and another one sensor does not pass into any material;
C. the output signal of sensor is after Signal-regulated kinase acquisition process, obtains the relevant parameters of fluid metal worn particle.
For making monitoring result accurate, resistance R1 is far longer than the equiva lent impedance of inductive coil.
Drive coil L1 and L2 parallel connection access excitation AC field module fd, drive coil is transfused to excitation AC field and produces alternating magnetic field, the induction electromotive force output that inductive coil LS1 and LS2 produces due to the change in magnetic field.The induction electromotive force differential concatenation that inductive coil LS1 and LS2 produces exports, and the fixed resistance very large with two resistances is connected into alternating current bridge exports.Electric capacity C and deflection machine R
pfor the balance adjustment of alternating current bridge.When the brachium pontis containing drive coil and inductive coil in sensor, by the fluid containing metal worn particle, another is obstructed out-of-date, and metal worn particle affects the magnetic field intensity of sensor, destroys the balance of electric bridge, and inductive coil exports the alternating voltage of respective magnitudes.When not having the fluid of abrasive particle by sensor, the voltage that two induced field coils of sensor produce is identical, and it is zero that bridge circuit exports.Output voltage size and metal worn particle concentration are directly proportional, and the metal worn particle concentration contained in fluid is larger, and output voltage values is larger.By Signal-regulated kinase to output signal acquisition and processing, reach the object to fluid metal worn particle concentration on-line monitoring.Certain subsequent treatment also comprises data and the result treatment step of some routines such as A/D conversion and microprocessor processes.
