When the instrument is measured, the Sensor is placed on the surface of the workpiece to be measured and started. The internal precision drive mechanism drives the Sensor to slide along the measured surface in a straight line with constant velocity. The sharp diamond stylus built in the Sensor senses the surface roughness and generates displacement, which changes the Inductance of the Sensor Inductance coil, thereby generating an analog signal proportional to the measured surface roughness at the output end of the phase sensitive detector. The signal is amplified and level converted into the data collection system, digitally filtered and parameter calculated by the DSP chip, and the final result is displayed on the monitor or output to the printer or PC.
Processing industry, manufacturing, testing, commodity inspection and other departments are mainly suitable for on-site inspection of large workpieces and production lines, as well as verification of inspection, Measurement, commodity inspection and other departments.
