SV 103 Personal Human Vibration Exposure meter is dedicated to hand-arm vibration measurements. The instrument meets ISO 8041:2005 and is the ideal choice for making measurements according to ISO 5349 and European Directive 2002/44/EC.
Hand-arm vibration is when mechanical vibrations are transmitted to the human hand when in contact with the surface of a vibrating machine such as an electric drill. This type of vibration is particularly harmful as it can cause pathological changes in the nervous system of the hands and fingers; commonly called white finger disease. As there is no cure for damage caused by vibration, the only effective regime is to take regular vibration measurements in the hazardous workplace environment and therefore ensure that damage is not caused in the first place. However, many currently used assessment methods for hand-arm vibration are subject to a very high level of uncertainty and typically vibration measurement accuracy can vary in the range of ±20% to 40% which makes a big difference in terms of white finger disease. The SV 103 from Svantek significantly decreases the measurement uncertainty as the instrument is attached to the user’s arm and is small enough to take daily vibration exposure measurements without interfering with normal working activities.
The SV 103 uses our latest accelerometer, the SV 107B, that has a contact force sensor in addition to the standard accelerometer. Contact force is the sum of grip force and push force and is therefore a measurement of how firmly a user is holding the tool being measured. This is a recommendation of the new standards and the reading from the contact force sensor is also displayed on the screen. The SV 107B accelerometer is based on MEMS, the very latest in transducer technology. MEMS gives many advantages including shock resistance, very low power and frequency response down to DC. The usage of MEMS breaks the technological barrier of a weight and dimensions additionally reducing the cost of the complete system.
The SV 103 is powered using rechargeable batteries charged through the USB interface which also enables easy interconnection between the instrument and a PC. The measurement data is safely stored in the large 8 GB memory. The instrument works with our powerful “Supervisor” software which allows instrument configuration as well as the viewing and exporting of measurement data and daily vibration exposure recalculations.
The colour OLED screen that offers excellent visibility even in full daylight completes the exceptional features of this instrument.
