Calibrating human vibration accelerometers!

Svantek has launched a new portable vibration calibrator. The hand-held SV110 is designed for verification of machine sensors as well as on-site checks of human vibration accelerometers, in accordance to ISO 8041.

Specially developed for in-situ calibration checks of hand-arm vibration meters mounted on hand or tool, the robust SV110 is ideal for use with Svantek’s popular SV103 and SV106 instruments.

With its compact design, the SV110 enables easy checks of sensors. Depending on the selected frequency (79.58 Hz and 159.2 Hz), the user may select the level of calibration from 1m/s² to 10m/s². Accelerometers are conveniently attached using mounting stud or disc, or via a dedicated adapter.

The calibrator menu provides selection between both metric systems ‘g’ and ‘m/s². The menu is simply operated by three push buttons and small OLED display.

Following the requirements of ISO 8041, the calibrator’s built-in reference accelerometer measures the cross-axis (transverse) vibrations to detect any disturbance to the calibration signal. Faults caused by transverse vibrations are indicated by two LEDs on the calibrator’s outer casing.

This innovative solution ensures stability of both the calibration level and frequency, independent from the mass of the test object.

Svantek’s SV110 portable vibration calibrator boasts built-in rechargeable batteries for 12 hours of continuous operation.
