High Frequency Non-contact Eddy Current Vibration Positioning Displacement Sensors
Eddy current sensor is a mechanical displacement or vibration amplitude can be converted into electrical signal output of non-electricity electrical measurement device.
It consists of a probe (sensor), extension cable and converter, (preamplifier), has a wide frequency response, linear measurement range, small size, strong anti-interference ability, easy to install and use, can be a long-term continuous and stable work and other advantages.
Especially with the characteristics of non-contact measurement, which will bring convenience to the dynamic measurement of rotating shafts and other rotating bodies, the probe can work in water, oil and other media.
