New all-in-one solar power system for popular noise monitoring terminal

Feb 18 2019 Read 888 Times

Reinforcing its position at the forefront of noise and vibration instrumentation for environmental and occupational health monitoring applications, Svantek UK has launched SolarBox, an all-in-one solar power system for use with its popular, low cost SV 307 Noise Monitoring Terminal.

The remote, pole mounted SolarBox provides essential power for Svantek’s small, lightweight SV 307 Noise Monitoring Terminal. The SV 307 has generated significant interest since its launch last summer which Svantek attributes to an extremely competitive price point and innovative Class 1 MEMs microphone with lifetime warranty.

The new SolarBox is a solar mount and enclosure in one neat unit, topped by a 110W DC-Solar 12V professional grade panel. It utilises monocrystalline SunPower cells offering quality, compact design and high outputs in low-light conditions. The built-in lead-acid battery helps ensure the system can run continuously, even in the worst of UK winters.

Protected by an IP66-rated waterproof, removable casing, Svantek’s SV 307 integrates a Class 1 (IEC 61672) sound level meter with 3G modem for fast data transfer over the internet to PC with standard connectivity. Offering optional airport and community characteristics, a Class 1 MEMs microphone enables wide frequency range up to 20 KHz with the measurement data stored on a microSD card.

The energy efficient NMT incorporates an innovative patented system check with an inbuilt reference sound source producing level of 100dB at 1 KHz. As an option, the SV 307 can perform real-time frequency analysis in 1/1 and 1/3 octave bands and save results with the time history data. In addition, it can record the audio signal as standard WAVE files for noise source recognition.

A large colour OLED display and 10 push buttons enable easy configuration of the NMT in the field removing the need for an external handset or reconnection to a PC.
The large windscreen is highly efficient in reduction of wind noise effects even at high wind speeds. Metal spikes protect the NMT from birds.

The SV 307’s waterproof casing can be easily mounted to a post and removed for quick access to the user interface. It also offers protection against extreme weather conditions whilst fulfilling Class 1 accuracy.

The SV 307 has an internal Li-Ion battery and interface for connecting the SolarBox. A waterproof mains adapter for charging the battery and powering the station is also included for continuous operation in the field.

Svantek’s SvanNET cloud service monitors the wireless communication, powering and access to the SV 307 data. The scope of the basic SvanNET can be extended with multipoint project management that offers data storage in the cloud, data sharing, advanced alarming and reporting features. SvanNET is an on-line solution which means it doesn’t require software installation and is accessible through a web browser. The responsive design enables use of SvanNET on various devices such as smartphones or tablets.

The SV 307 is available with a number of optional functions including an accurate GPS hardware module providing information on the localisation as well as measurement time synchronisation.

The SvanPC++ Environmental Measurements feature is designed for post processing of data recorded by the NMT. It offers a powerful calculator and an automated noise event finder for noise source identification.

The option for 1/3 octave real-time analysis allows measurement of the noise frequency contents and is used for verification of noise sources in the environment. Plus time domain signal recording to WAVE format works during measurement and is logged in parallel to a time history. Once downloaded to PC it can be played back. The SV 307 is supplied with a factory calibration certificate and 36-month warranty card.

Svantek is part of the AcSoft Group which also comprises AcSoft Sound & Vibration, AcSoft Health & Safety and GRAS UK.
