Vibration sensorThere are many types of calibration, and their working principles and testing parameters vary greatly, so the calibration items are also different. In general usage units and occasions, the sensitivity, frequency characteristics, and dynamic linear range are mainly calibrated. The calibration devices for vibration sensors mainly include vibration tables, earth gravity field calibrators, low-frequency rotary table calibrators, impact calibration devices, and centrifuges.

1. Vibration table

There are many types of vibration tables, including electric, electro-hydraulic, mechanical, piezoelectric, etc., or divided into high frequency, medium frequency, low frequency, etc.VibrationA vibration table is generally composed of a main body, a control part, a monitoring part, and a data processing part. Electric vibration table is the most commonly used calibration device in sensor calibration, accounting for more than 80% of the total number of vibration tables used.Electric vibrationThe platform is mainly composed of an activity system (including exciters and workbenches), a magnetic circuit system, elastic elements, guiding mechanisms, and cooling devices.

2. Impact calibration device

Impact calibrationAlso known as transient calibration, it is currently commonly calibrated using shock pulses with acceleration changing in a radial pattern. The peak acceleration value and impact duration are the two main parameters that characterize this type of impact pulse.
