Noise and vibration monitoring
01 September 2017
Svantek will be showing a wide range of high performance noise and vibration monitoring instrumentation at Health & Safety North 2017, including its SV103 personal vibration dosimeter and ATEX and IECEx Intrinsically Safe (IS) SV104 personal noise dosimeter for use in potentially explosive work environments.
The company will also be exhibiting its SV100A wireless whole-body exposure meter & analyser in a seat-pad which is designed to automatically detect the operator, the SV106 six-channel human vibration meter and SV971 sound level meter and analyser. In addition, the Gilian personal air sampling pumps from US-based Sensidyne and Heat Shield from LSI Lastem will also be on display.
Developed for the estimation of the effects of vibration on workers’ health, comfort, perception and motion sickness, Svantek’s easy to operate SV 100A can take measurements both on a vehicle’s seat-pad and seat-back. It is equipped with four push buttons and a small OLED colour display that allows basic configuration in the field. The bluetooth interface allows current results to be previewed on a smartphone or tablet using Svantek’s Assistant Android Application. The smartphone app can also signal an alarm when set vibration limits are exceeded.
The SV 100A enables the automatic detection of an operator in the workplace. By default, the instrument is configured for seat measurements in a horizontal direction but this setting can be easily changed. It incorporates both RMS and RMQ detectors which allows the calculation of daily vibration exposure based on RMS and VDV simultaneously.
Amongst the Gilian personal air sampling pumps on display will be the high performance GilAir Plus, specially designed for simultaneous high and low flow personal measurement of particulates, vapours, gases and metal fumes. Widely recognised as the most versatile personal air sampling pump available, the compact and lightweight GilAir Plus offers an impressive air sampling range from 1ml/min up to 5000ml/min - without the need for any external adapters.
The compact Heat Shield system is designed to help reduce the risk of employees overheating whilst working in hot environments, such as bakeries and foundries, where the use of ovens and furnaces mean that heat stress is a constant concern for employees. As well as measuring WBGT (wet bulb temperature – the most widely used and accepted index for assessing heat stress in industry), it can also monitor Heat Index, PMV (predicted mean vote), PPD (percentage people dissatisfied), PHS (predicted heat strain) and many more parameters.
Svantek’s IS SV104 is a cable-free personal noise dosimeter that can be easily attached to the user’s shoulder, close to the ear using assorted mounting clips. It offers a wide range of features including octave band analysis for helping to select hearing protection and audio recording.
The full colour OLED screen displays information in both text and graphical form plus offers excellent visibility even in full daylight. Svantek’s SV104 also incorporates a virtually indestructible MEMS microphone enabling easy calibration using most commonly available acoustic calibrators and inbuilt tri-axial accelerometer for vibration shock detection. Measurement data is safely stored in the large eight GB memory and the instrument works with Svantek’s specialist Supervisor health and safety software package.
Svantek’s SV103 is a small, rugged instrument which simply attaches to the user’s arm whilst the lightweight MEMS accelerometer straps to the hand. This device features an easy to read colour OLED screen and all data can be quickly downloaded to a computer for analysis. The SV103 also has an additional contact force transducer that measures how firmly the tool is being gripped.
