Bruel & Kjaer 4294 Vibration Calibrator
| B&K 4294 | Vibration Calibrator - hand held | £ 5 a day * |
Uses
Quick, easy field calibration of vibration measurement and recording systems
Features
The B&K Accelerometer Calibrator is a small, self contained vibration reference source.
It is intended for rapid calibration and checking of vibration measurement, monitoring and recording systems utilizing piezoelectric accelerometers as well as other vibration transducers - up to a maximum mass of 70 grams.
The 4294 permits accurate adjustment of measuring instrumentation to indicate a standard acceleration level of 10 ms-2 thus
calibrating the system for correct measurement of other vibration levels
The reference level may also be used for velocity & displacement calibration: 10 ms-2 ~ 160 Hz = 10 mm/s-1 and 10 µm respectively.
Not only will a system calibration using the 4294 automatically take into account the influence of the connecting cables on the voltage sensitivity of the transducer but it will also provide a quick check on the correct function of the complete measurement system
