Vibration Unit Tester
BK2020B
We developed the BK2020B as an upgrade to our BK2020 to test the electrical specifications (RPM, current, drop pulse, start up voltage) of your cylindrical or coin type vibration units. You can also test vibration level, noise, isolation resistance, and the DC resistance. The DUT power supply and all measurement components are self contained, so external devices aren't needed and the tester uses DSP, making it capable of fast, highly accurate and reliable measurements. The BK2020B is very versatile. It can be set up as a stand alone machine, or used with a PC and software for access to more information, and to save the data for analysis. Either version is great on the product line but you may also use it for QA, QC and development.
