Vibration Calibrator [SV 111]

SV 111 Vibration Calibrator is the State of the Art instrument designed for in-situ checks according to ISO 8041. In-situ checks are intended for application in the field prior to and following a measurement or series of measurements. They act as a check of the instrument’s basic calibration and functionality.

The SV 111 is suitable for calibration checks of various types of vibration meters at different frequencies from 16 Hz up to 640 Hz. Depending on the selected frequency user may select level of calibration from 1 m/s2 to 10 m/s2. The design of the calibrator is based on the built-in triaxial reference accelerometer and microprocessor-controlled shaker. Following ISO 8041 requirement the reference accelerometer measures the cross-axis / transverse vibrations to detect interference on the calibration signal. Faults caused by transverse vibrations are indicated by three LEDS on the calibrator’s panel. This unique solution ensures the excellent stability of the calibration level & frequency independently from mass of the testing object. Shaker can be loaded with large weight up to 1 kilogram.
