Acceleration Pickup Frequently Asked Questions
Question number FAQ-1380
Regarding the use of NP-3210 wax.
Is the "frequency range" in the catalog specifications the value when installed with wax? Also, will the wax soften due to the temperature of the object being measured? If it softens, will it have any impact on performance? |
The frequency range specified in the catalog is for when fixed with instant adhesive.
When installed with wax, the frequency range is affected by the thickness of the wax. Please refer to the instruction manual for the frequency characteristics.
Wax softens at around human body temperature (36 degrees Celsius). Beyond that, it becomes softer and melts. Additionally, its frequency characteristics deteriorate. Please use wax at temperatures close to body temperature.
Warm the wax with your fingertips to soften it, roll it into a ball about 2 mm in size, place it on the measurement target, and apply it thinly and closely using the NP-3210. The wax hardens as the temperature drops, firmly securing the NP and improving frequency characteristics.
If the object being measured is a magnetic material, I would like to use a magnet for the pickup attachment method. Are there any issues with this? The method involves gluing the pickup to a small magnet (using instant adhesive) and attaching the magnet surface to the object being measured. |
There is no problem. The frequency characteristics are affected by the adhesion between the magnet and the target. If there is no horizontal vibration and only vertical vibration, frequencies close to 10 kHz are possible. You can combine the optional flat table with the NP-0102 magnet base and bond the NP-3210 to the flat table.
| Please let me know if there are any precautions for use. |
Please refer to the instruction manual for NP-3210.
