INTRODUCING THE SV 973 SOUND LEVEL METER FOR MEASURING OCCUPATIONAL NOISE

sv 973

New Class 2 instrument boasts patented MEMS microphone, lifetime warranty and measurement range up to 141dB Peak

Svantek has launched its SV 973 sound level meter for reliable and accurate measurement of noise in the workplace. The new Class 2 instrument features a patented MEMs microphone with lifetime warranty and measurement range up to 141dB Peak.

The SV 973 is a Class 2 sound level meter in accordance to IEC 61672-1:2013 with a wide frequency range up to 10 kHz. The meter’s measurement range from 25 to 128 dB enables it to be used for industrial and environmental noise monitoring applications.

For measurements of noise at work, the intelligent sound exposure meter function limits the frequency range to 10 kHz and shifts the dynamic measuring range of sound level meter to 141 dB Peak.

The instrument can be automatically calibrated in the field and offers an operating time up to 38 hours on AAA replaceable batteries. The USB connector can be used for communication with PC software as well as for powering the instrument from an external battery or PC.

The time history logging of results such as Leq, Max, Min and Peak Data is stored on built in 8 GB memory and can be easily downloaded to a PC using the Supervisor or SVANPC++ software.

The SV 973 incorporates a full colour, high contrast OLED display which can be used in sunlight and at night. The size of display is a perfect compromise between power savings and visibility whilst the lack of back light gives the instrument more battery operating time.

In addition, Svantek’s SV 973 offers several optional functions which can be activated at any time by ordering the relevant codes. Audio recording is synchronised with a noise time-history and it can be opened and played back in supervisor software enabling noise source recognition. The recording is programmable and can be triggered on threshold or time and the length of recording can be set as well.

Another option is Frequency analysis of the signal in 1/1 or 1/3 octave bands. The 1/1 octave analysis is often used for selection of hearing protectors. The 1/3 octave function determines the influence of high or low frequencies on overall values.

In addition, the SV 973 can also be used for building acoustics applications with the optional RT60 analysis which provides reverberation time calculation for 1/1 octave bands (from 63 Hz to 8 kHz) or 1/3 octave bands (from 50Hz to 10kHz) and three total RMS levels (A, C and Z weighted). Whole measurement process and calculations implemented in SV 973 fulfil the ISO 3382 standard.

Svantek’s SvanNET portal offers noise, vibration and dust monitoring plus new 24/7 support functionality

All-in-one cloud-based solution provides multi-point internet connection for alarming, reporting and management in convenient central location

Svantek’s well proven SvanNET cloud-based solution now offers noise, vibration and dust monitoring with new 24/7 support functionality ideal for large infrastructure projects. The enhanced, all-in-one portal offers multi point internet connection with the company’s high performance instrumentation to provide alarming, reporting and management in a convenient central location.

Svantek’s cost effective SvanNET has been specially developed for use with the company’s advanced SV 258 PRO vibration and SV 307 noise monitoring stations, as well as its exciting new Met One ES-642 Remote Dust Monitor. It provides measurement status, alarms indication, power source including battery charge and external power information as well as GSM strength.

The new ES-642 remote dust monitor is an industrial air quality sensor designed to provide accurate measurements of particle concentration in both indoor and outdoor environments. Supplied in a rugged waterproof enclosure, it includes an LCD display to provide information about particulate concentration, flow rate, instrument status and power.

Svantek’s SvanNET enables web interface, access to data files in the instruments and status alarms for battery or memory. It sends out advanced alarms for noise, dust and vibration parameters which can be set for different times of the day rather than just during normal work hours. It means emails and SMS messages can be delivered to the correct person regardless of shift pattern.

Aidan Hubbard, Svantek’s Sales Director comments: “SvanNET is the central portal for all noise, vibration and dust monitoring data to be displayed and managed. Users are now looking for an easy to use all in one solution instead of running multiple portals for multiple instruments. They would much rather have a single portal and see everything in one place.

“In addition, a new support functionality enables users to easily get back up and help from a Svantek engineer on a 24/7 basis which is particularly ideal for large infrastructure projects.”

Sharing access with key people is made easy with Tokens. This feature does not require a password or username to enter but provides a website with live data streaming.  Whilst the user is unable to make changes to the project, it is useful for making data more accessible.

Svantek’s IEC61672 class 1 SV 307 noise monitoring station now has the ability to alarm from vibration or tilt detection. This alerts users when it has been adjusted by strong winds or from attempted theft. It can also be alarmed from GPS movement although this is more appropriate for time synchronisation of multiple systems.

As an online solution, SvanNET does not require software installation and is accessible through a web browser or dedicated App for Android and IOS platforms. The responsive design enables use of SvanNET on various devices such as smartphones or tablets.

SvanNET allows usage of all types of SIM cards with the Svantek monitoring station modem regardless if they have public or private IP. Once a card is inserted into the instrument it automatically connects to SvanNET.

The web user interface is easy to use and intuitive to operate. The connectivity service offers management and gives full control of the monitoring system using any web browsing device like a mobile phone, tablet or PC.

The online preview template provides current results, time-history graphs as well as information on status of monitoring points. The preview website can be customised with logos and individual project names. The preview content can be configured in SvanNET interface that works as the Content Management System (CMS).

To ensure reliability and data security, SvanNET has been located on the Microsoft Azure™ cloud platform that works through the global network of Microsoft-managed data centres.

The SvanNET project is an optional feature designed to offer fully automated management of multi-point noise and vibration monitoring tasks. Tools such as Automatic Files Download, Data Storage, Advanced Alarms and Data Sharing for generating restricted access log ins to SvanNET enable unattended monitoring.

The functionality of SvanNET Projects allows grouping of monitoring stations so that alarms and reports are separately defined for each project. The data files are also grouped automatically in accordance with Project assignments.

Noise, vibration and dust monitoring for planning consent

Sound, vibration and dust monitoring can be a bit of a minefield at the best of times but when you add all the extra variables for monitoring on a large construction site then getting everything set up correctly can be critical.

At Svantek we’ve run a number of seminars near our offices in Bedfordshire and they’re always very popular. On Weds 9th May we are running one covering many aspects of monitoring on construction sites for planning consent compliance from an acoustic consultants’ perspective and then on Thur 10th May we tackle the same subject but from a building contractors’ perspective. Experienced speakers cover many key topics from the standards you need to adhere to right through to accessing your data via a web portal. We look at a number of subjects including transducer selection, calibration and also some real life examples.

Speakers at the event include John Shelton BSc(Hons) MSc MIOA who chairs the instrumentation working group for the Institute of Acoustics.

The impact of contact force on the accuracy of hand-arm vibration measurement

We recently attended the 52nd Human Response to Vibration Conference & Workshop at Cranfield University where Svantek Poland’s Marketing Manager, Jacek Kuczynski, gave a presentation on ‘The impact of contact force on the accuracy of hand-arm vibration measurement’.

https://www.cranfield.ac.uk/events/events-2017/52nd-uk-conference-on-human-response-to-vibration

Below is an abstract from a paper produced by Jacek and Piotr Kowalski Ph.D (Eng) from the Central Institute for Labour Protection in Warsaw which details a recent study into the use of hand-arm vibration adapters and the accuracy of hand-arm vibration measurements, in function of the contact force. The Institute performed 240 measurements where the impact of coupling force on vibration magnitudes was assessed using Svantek’s SV106 human vibration meters and SV105AF hand-arm adapters.

The two Svantek SV106 human vibration level meters meet ISO 8041:2005 requirements, and are designed to perform measurements in accordance with ISO 5349-1 and ISO 5349-2 standards, with special SV105AF hand-arm adapters mounted on handles of vibration exciters.

Abstract

Measurement of hand-arm vibration with the use of a hand mounted sensor ensures the most representative measurements, taken at the point of contact of hand with a vibrating tool.

When measuring vibration on a hand, simultaneous measurement of contact force verifies whether the force magnitude is sufficiently rigid. The contact force also provides information on operator’s work schedule and may help to instruct users if they are using excessive or too little force when working with hand-held tools.

Additionally, by knowing both the coupling force value and the vibration acceleration, it is possible to calculate actual vibration energy dose that has been transferred to a hand.

The results proved that measurements taken with hand-arm adaptors provide correct vibration results regardless of contact force changes and type of vibration signal. The study has also indicated that it is necessary to define a minimum force threshold in order to mitigate the uncertainty related to the contact between hand and a vibrating tool.

Conclusion

The study proved that the effect of changes of the force thresholds applied by the operator are irrelevant to the measured vibration acceleration values. This assumption is valid for the forces above threshold of 20 N, below which it is necessary to ensure the correct coupling between hand-arm adaptor and vibrating surface. Together with the force level drop below 20 N, the uncertainty related to the coupling increases rapidly. However it is necessary to note that in practise, for tools generating high vibration amplitudes, the threshold of 20 N may not guarantee the perfect coupling, therefore higher threshold levels should be established.

Summary

At the time the ISO 5349 standard was introduced it was practically impossible to perform force measurements together with tri-axial vibration measurements due to limitations in hardware.

At the moment very small force transducers can be fitted right next to the MEMS-technology-based vibration accelerometer in a form of hand-arm adaptor as specified by ISO 5349-2 and ISO 10819 standards. In comparison to the technique of mounting sensor on a tool, the use of contact force allows defining the actual vibration exposure, whereas mounting on a tool bears the uncertainty of including into tests the periods when there was no contact with the operator’s hand.

As it has been proven, the use of hand-arm adaptors provides the same accuracy of vibration amplitudes as in case of standard piezoelectric vibration sensors mounted on a tool, but additionally offers the advantage of the best possible location of the measurement point – exactly at the point of transmission of the vibration signal to the hand of an operator and provides information on the actual exposure to the vibration.
