Tri-axial vibration meter for human-related vibration measurements.
The VM-54 Tri-axial Vibration Meter is designed to assess human response to both whole-body and hand-arm vibrations. Ideal for evaluating passenger comfort on vessels and merchant ships, it offers a comprehensive measurement system for vibration analysis. With the capability to measure across single-axis to triaxial dimensions, the VM-54 provides accurate acceleration level measurements and frequency analysis, making it a versatile tool for optimizing shipboard comfort and safety.
Each VM-54 includes a 18-month warranty.
Accelerometer, Tri-axial, 0.12 pC/ms^2, –50 to 160 ºC, 4.7 g
3-Channel Preamplifier/Input Adaptor for use with PV-97C Tri-Axial accelerometer or other piezoelectric accelerometers
For use with VX-54WB1 Whole Body Vibration program option
Input: 100 to 240 V AC, 50/60 Hz, Output: 6 V DC.
The VM-54 Tri-axial Vibration Meter is built to be expandable and upgradable. All program options are designed for easy installation through Rion’s streamlined installation process, which is both quick and user-friendly. Each option is pre-installed on CF cards, enabling users to independently install the software by inserting the CF card into the instrument and following the installation procedure.
VX-54WS Marine Vibration Program Option
ISO 6954:2000 outlines the method for measuring and recording vibrations within the crew and passenger accommodation areas of ships to assess comfort and suitability. The current system for marine vibration measurement includes the tri-axial accelerometer PV-83CW (for floor placement), the 3-Axis Vibration Meter VM-54, and the Marine Vibration Card VX-54WS. This setup enables measurements and evaluations that comply with the applicable standards. The system covers a frequency range from 1 to 80 Hz, utilizing the Wm frequency weighting as per ISO 2631-2:2003.
Accessories included with VX-54WS
VX-54WB1 Whole Body Vibration Program Option
Vibrations generated in vehicles are transmitted to the human body through the feet, seat, and backrest. To assess the impact of these vibrations, the ISO 2631 series provides guidelines focused on vibration perception, comfort, and potential health risks. These standards address both periodic and irregular whole-body vibrations, with specific frequency weighting for various vibration transmission paths and the three axes. The whole-body vibration measurement system includes the tri-axial Seat Measurement Accelerometer PV-62, the 3-Axis Vibration Meter VM-54, and the Whole Body Vibration Card VX-54WB1. This comprehensive system ensures measurements and evaluations are fully compliant with the applicable standards. The system covers a frequency range from 1 to 80 Hz, utilizing the Wk, Wd, Wb, Wc, Wj, Wm, Wg frequency weightings.
VX-54WH Hand-Arm Vibration Program Option
Vibrations generated by hand-held tools are transferred to the operator’s hands, arms, and shoulders. ISO 5349-1 and ISO 5349-2 provide guidelines for assessing these vibrations. These standards define frequency weighting characteristics and evaluation factors, as well as offer detailed instructions on accelerometer mounting. The hand-arm vibration measurement system includes the PV-97C tri-axial accelerometer, the 3-Axis Vibration Meter VM-54, and the Hand-Arm Vibration Card VX-54WH. This system enables vibration measurement and evaluation in accordance with the applicable standards. The system covers a frequency range from 8 to 1000 Hz, utilizing the Wh frequency weighting.
VX-54FT FFT Analysis Program Option
This program option enables the possibility to perform 3-channel FFT analysis. Previously measured analysis data can be loaded and shown in an overlay graph display together with current analysis data. Frequency resolution can be adjusted for 0.125, 0.25, 0.5, 1.25, and 2.5 Hz. Supported frequency windows include Hanning and Rectangular.
