The SV 111 is a multi-frequency vibration calibrator designed for field verifications with ISO 8041. The SV 111 is suitable for calibration controls of various types of vibration meters at different frequencies from 16 Hz to 640 Hz. selected frequency, the user can select the acceleration calibration level from 1 m/s2 to 10 m/s2, being able to check objects with a weight up to 1 kilogram at 16 Hz. The design of the calibrator is based on the triaxial reference accelerometer built-in and microprocessor-controlled stirrer. Following the requirement of ISO 8041, the accelerometer of reference means the transverse shaft/transverse vibrations to detect interferences in the calibration signal. Falls caused by transverse vibrations are indicated by three LEDs on the calibrator panel. This unique solution ensures the excellent stability of the level and the frequency of calibration regardless of the mass of the slurry object. For the verifications of the calibration of triaxial sensors, a set of dedicated adapters is available that include a special adapter for whole body sensors (seat pads) from Svantek for direct mounting on the shaker. It is possible to conveniently couple other types of vibration transducers by means of a mounting bolt, a mounting disc, or a specific adapter. The SV 111 vibration calibrator is the best option for verifying vibration sensors and accelerometers according to ISO 8041. It is a robust and portable equipment that allows this type of instrumentation to be verified at different accelerations and selectable frequencies:
• Calibrator for field vibrations according to ISO 8041
• Selectable frequency of 15.92 Hz/79.58 Hz/159.2 Hz/636.5 Hz
• Selectable acceleration between 1/2/3/4/5/6/7/8/9/10 m/s2 depending on the frequency
• Frequency error less than 0.5%
• Rechargeable battery for up to 20 hours of operation
• Instrument status LED’s
• OLED display with information on calibration parameters
• Maximum calibration weight of 300 g (79.58 Hz), 200 g (159.2 Hz/636.6 Hz) and 1000 g (15.92 Hz)
