VB-2000 portable vibration meter
First, the product overview
Features:
1. Simple structure and convenient operation. The integrated design installs the accelerometer and instrument in a single housing. When using it, simply align the meter probe with the object to be measured and press the measurement button to measure.
2. The meter is powered by a 9V laminated battery. It has a low voltage detection and indication function. When the battery voltage drops to affect the measurement accuracy value, the LCD display has a battery symbol to remind the user to replace the battery.
3, with automatic shutdown function, so that the battery has a longer life.
4. The meter has a latch function. When the measurement button is released, the data can be latched for easy use and reading.
5. The meter mainly reflects the vibration of the measured object from the energy point of view. It can measure the root mean square value of the vibration speed, the peak-to-peak value of the displacement and the half-peak value of the acceleration, thus satisfying various vibration measurement needs.

Third, the working principle
The acceleration sensor signal is first filtered and amplified to obtain the acceleration signal, and then the first stage is integrated to obtain the speed signal. The signal is then integrated into the first step to obtain the displacement signal. The three signals are selected by the measurement selection switch to perform a cross-DC conversion. And A / D conversion, Zui sent three and a half LCD display.
