Bruel & Kjaer 4294 Accelerometer Calibrator
|B&K 4294 : Accelerometer Calibrator, hand held, battery powered||£ 5 a day *|
Type 4294 permits accurate adjustment of measuring instrumentation at a standard acceleration level of 10 ms-2 (0 – 70 g load). The reference signal may additionally be used for velocity and displacement calibration, at 10 mms–1 and 10 μm respectively.Uses
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 ~ 159.15 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
The vibrating 'table' has a 10-32 UNF thread. Also included is a YQ 2962 steel stud and a DB 2996 mounting disk (10 grams) which has a 3 mm thread and YQ 2007 stud for miniature accelerometers. The calibrator is delivered in a small leather pouch.* Our standard hire charges are based on a 4-day minimum period, details other options.
