Select of Probe
The principle of selecting probe
When measure the displacement, speed, acceleration of low frequency 10Hz~1KHz, select long probe, when measure the displacement, speed, acceleration of high frequency of 1KHz~10KHz, select short probe, short probe also used to maintain the reliable accuracy, when there is a flat frequency above 1KHz, there is no need to use probe.
Short probe
Short probe is necessary for frequency of 10Hz~10KHz. It is more reliable.
Long probe
When the short probe is hard to test, use 8cm long probe. In low frequency of 10~1KHz, long probe has good response, above 1KHz, the response will reduce.
No probe
It is ok when the surface is well connected, if the sensor and workpiece is not well connected, the response frequency can’t be guaranteed. If the surface is rough, cover some wax to guarantee the frequency response.
