Human Vibration Analyzer - Type 4447
Contents
1. An increase in the number of hand arm and whole body injuries caused by vibration is the consequence of the use of modern appliances that are powered by external power sources Hand tools machinery and heavy vehicles cause vibration the harmfulness of which depends on its intensity and frequency content and the time of exposure Human Vibration Analyzer Type 4447 a portable system for acquisition measurement and evaluation of human vibration is designed to meet the requirements of those who wish to monitor and reduce the exposure of human operators to the harmful influences of such vibration USES AND FEATURES USES e Hand arm vibration measurements 1 to 1250Hz e Whole body vibration measurements 1 to 80 Hz e Low frequency whole body vibration measurements down to 0 4Hz e Linear mode 0 4 to 1250 Hz for calibration FEATURES e Compact stand alone instrument with an internal power source e Versatile graphics display for control of the instrument and analysis of results Tentative PRODUCT DATA Human Vibration Analyzer Type 4447 Briel amp Kj r 060152 Only four buttons to control the instrument s functions ideal for field work All the necessary data is displayed for instant assessment of exposure to vibration Very few cables only one cable connection to a transducer in basic setup USB connection to a computer for post processing and archiving Risk assessment following the good2. practice guide for human vibration Briel amp Kj r lt Introduction Measurement Options Display This instrument has been designed for those working with human vibration and who require quick and reliable results Using Type 4447 measurements can be made easily as only the necessary parameters required by EU Directive 2002 44 EC are calculated The instrument was developed and designed on the basis of input from several groups concerned about human vibration Consultants working with measurements of and risk evaluations caused by exposure to occupational vibration Departments for occupational health Manufacturers of building machinery freight vehicles and other machinery causing vibration Manufacturers of anti vibration pads seats and personal protection equipment Manufacturers of all kinds of hand tools Educational institutions Medical institutions Type 4447 simultaneously measures and calculates the following parameters Three components of the running RMS vibration weighted or unweighted a ay Three components of the peak vibration weighted or unweighted a peaks Ay peak 4z peak The crest factor for each axis The frequency weighted hand arm vibration awx awy awz The frequency weighted whole body vibration awx awy awz The combined vibration on all 3 axes as a vector sum ay with implementation of the k factors for whole body MTVV Maximum Transient Vibration Value MSDV Motion Sickne
