30 Years of Svantek and 10 Years of Svantek UK

By John Shelton

The Svantek company was set up in 1990, after the collapse of the Iron Curtain, by a small group of highly qualified acoustic and electronic engineers, to produce the best in sound and vibration instrumentation. With a strong market in the Eastern Bloc countries, export to Europe and beyond was slow to start with, but in the UK, Acsoft took on the range in 1996, starting with the 912 portable sound & vibration analyser. This unique instrument had a staggering capability, offering both FFT and 1/3 octave digital filtering in a portable analyser, something only previously possible with a car load of kit!

Initial resistance to ‘inferior ex-communist’ equipment (the Skoda effect) was quickly overcome, and early adopters came to rely on the high performance/cost ratio, as well as the instrument reliability.

As the range developed, first the 94x series followed by the 95x instruments, Svantek soon became mainstream on the UK market in the environmental health and consultancy markets, primarily in environmental noise & vibration measurement. The accession of Poland into the EU in 2004 made sales and support much easier, and CE marking and ISO9000 ensured quality, up with the best.

Svantek Poland has always been strong in their own markets for instruments for occupational noise & vibration, something outside AcSoft’s area. To address this, Svantek UK was set up in 2011 as a joint partnership to focus initially on the health & safety market, and allow investment in market development.

Whilst this has been a success, the environmental monitoring market has also taken off, making Svantek a key player in both markets worldwide.

Svantek has always been about innovation, and this can be highlighted by the following world ‘firsts’:

First hand-held FFT and 1/3 octave analyser (912)

First 4-channel sound & vibration analyser (948)

First MEMS-based noise dosimeter with Bluetooth and 1/3 octaves (104)

First 6-channel human vibration analyser (106)

First human vibration dosimeter PVEM with MEMS accelerometer (103)

First Class 1 pocket sound level meter (971)

First MEMS-based Class 1 noise monitoring station (307)

First Class 1 noise monitoring station with directional information (SV200A)

And all this comes with attention to standards and quality. In fact, one calibration laboratory once commented “we can always count on Svantek equipment when it comes in, as it’s always straight down the line when it comes to calibration tolerances”

Innovation is set to continue with the R&D department busier than ever.

Svantek UK Ltd is the UK subsidiary of Svantek in Poland. The company was formed in January 2011 as a joint venture between Svantek and AcSoft Ltd, the company that previously distributed Svantek’s products in the UK.

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.
