Datasheet

The Bruel & Kjaer 2511 is an exceptionally wide range instrument which is used in conjuction with a piezo-electric accelerometer to measure mechanical vibration and shock in terms of acceleration, velocity, and displacement. It is completely portable and is built to a high standard of accuracy and stability making it suitable for both laboratory and field conditions. The instrument is fully calibrated in both Metric and British units and has a change amplifier input which allows the use of long cables between the accelerometer and the meter without any reduction in sensitivity.
 

The Bruel & Kjaer 2511 Vibration Meter is a valuable tool in the investigation of the dynamic behavior of mechanical structures. It can be used to monitor vibration levels in production machines on a periodic basis so that any increase can be noted and corrective action taken before any machine failure. It may be used in production quality control to ensure that manufactured goods are within specification before dispatch. It can be used in tracking down the source of vibrations which produce noise so that damping can be applied. In design and development, it will be used in assessing the vibration "quality" of a prototype. In civil engineering it will be used in the investigation of vibration on roads, bridges, dams, buildings etc. Its operation is simple and quite suitable for use by non-scientific personnel not conversant with electronic instrumentation.
