Portable Vibration Calibrator
Portable Vibration Calibrator
HBK India (Bruel & Kjaer) offers a wide range of
portable vibration calibrator - Type 4294.
- This portable vibration calibrator provides accurate acceleration, velocity and displacement calibration of accelerometers, and general instrumentation. The calibrator is handheld, battery-powered and an essential tool for everyday use in changing environments
- The vibration calibrator enables accurate adjustment of measuring instrumentation and transducers, such as accelerometers 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. Using the portable vibration calibrator is very straightforward: Simply attach a transducer to the calibrator table using a 10–32 UNF Steel Stud (YQ-2962), and that's it.
- Use scenarios: precise field calibration of vibration transducers; rapid calibration and checking; quick, easy field calibration of vibration measurement and recording systems.

- Its features include: small, lightweight, and battery-driven; leather case for impact protection; designed for everyday use in harsh environments; acceleration, velocity and displacement calibration; high-precision, crystal-controlled servo operating at 159.15 Hz (1000 rad s–1); drop- and environment-tested according to IEC 60068; splash-proof according to IP 54 (IEC 60529
- The calibrator embodies an electromagnetic exciter driven by a crystal oscillator at a frequency of 159.15 Hz (1000 rad s–1).
- Servo feedback via a small accelerometer on the underside of the vibration table is used to maintain a constant and accurate vibration level - independent of the mass of the transducer under test.
