Its high frequency characteristics differentiates it from a normal vibrating screen. The high frequency vibrating screens usually operates at an inclined angle, traditionally varying between 0 and 25 degrees and can go up to a maximum of 45 degrees. Besides, it should operate at a low stroke and has a frequency ranging from 1500 - 7200 RPM.
The PCE-VT 1100 Vibration Meter is designed for quick measurements of an imbalance in machines and the examination of bearings and gears. The Vibration Meter is also frequently used to evaluate the state of small electronic motors.

A typical vibration measurement system includes a device to sense the vibration (accelerometer), and an instrument to measure the level of vibration. This equipment also has settings for measuring frequency, a frequency-weighting network, and a display such as a meter, printer or recorder.
ScreenWatch enables operators, controllers and service professionals to see real-time analysis of vibrating screen performance and bearing condition. If there is a problem, the system alerts you immediately, so you can perform the necessary maintenance before a minor issue becomes a major expense.
Description. The application analyzes the data from the phone's accelerometer and builds a vibration spectrum. This allows the evaluation of not only the strength and frequency of the vibration, but also the speed of rotation of various mechanisms: fans, motors, various rotating components; since the vibration frequency often (but not always) coincides …
Vibration measurement instruments and vibration analyzers can accept a number of different types of transducers, including acceleration, linear velocity, proximity and displacement, rotary velocity, and temperature. In addition, many vibration instruments can take generic signal inputs, including voltage, current, frequency, and serial inputs.
