New Break-through : World’s First Embedded Eddy Current Displacement Sensor
After many years R & D, we finally resolve the problem that eddy current sensor probe is easily affected by metal nearby. We developed an embedded eddy current displacement sensor . In ZA21-Q embedded eddy current sensor, its head is completely embedded inside the metal shell so as to protect probes from damage caused by external forces.This technology greatly extends the lifespan of probes.
