Bruel & Kjaer 4294 Accelerometer Calibrator


 
B&K 4294 Vibration 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
 
Features
 

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

Manufacturer's Specifications

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.
