Moisture Monitoring for SF6 / Air Circuit Breakers

by Moisture Control & Measurement Ltd     based in Wetherby, UNITED KINGDOM

SF6 (sulphur hexafluoride ) or air is used as an insulation gas in circuit breakers . Excess moisture in these gases causes arcing, which can trip the circuit breaker and cut off power to the distribution network. More seriously, such arcing can lead to physical damage of equipment and, on occasion, death of plant operatives (please ask for our case study on circuit breakers).

Sound Instrumentation for Industrial Hygiene

by Norsonic AS     based in Lierskogen, NORWAY

Industrial hygiene is separated into two main applications - Noise at Work and Human Vibration. Norsonic has during the past year expanded the product portfolio to cover both applications. By close cooperation with our customers and health and safety research institutes we have designed a carefully balanced selection of measuring tools and application software that covers both the vibration and noise domain.

Noise monitoring solutions for urban noise

by Brüel & Kjær Sound & Vibration Measurement A/S     based in Nærum, DENMARK

The sounds in a city are central to our quality of life. Constant exposure to noise effects both our physical and psychological health, and our ability to learn and communicate.

Sound level measurement for safety regulations

by Casella     based in Kempston, UNITED KINGDOM

Hand held instruments for the measurement of an employee`s noise exposure. Frequency analysis within Sound Level Meters can also be used to determine the correct selection of hearing protection.

Meteo Information for Safe Operation

by Mierij Meteo b.v     based in De Bilt, NETHERLANDS

In the industry segment meteo information is essential for safe operation. To deal with emergencies, accurate real-time information on wind conditions (direction and speed) is crucial. In some cases we feed this data directly into safety applications which models and predicts the progression of released gas clouds.

2-Channel sound insulation for building acoustics

by Brüel & Kjær Sound & Vibration Measurement A/S     based in Nærum, DENMARK

Façade sound insulation is measured like sound insulation between rooms, except that one `room` is actually open space. The sound level is measured inside the receiving room and outside the façade of the building. The level difference is then corrected for the influence of the reverberation time and background noise level in the receiving room. Finally a single-number index is calculated by averaging over all the frequency bands. A loudspeaker source can be used for the measurement, giving a choice of sound incidence angle. But in practice, placing the loudspeaker and getting a high enough sound level can be difficult.

Perimeter Monitoring and Area Monitoring

by Boreal Laser Inc.     based in Edmonton, ALBERTA (CANADA)

GasFinder2 can be permanently installed to monitor chemical and petroleum plants for both combustible and toxic gases. GasFinder2 can be used to replace arrays of point sensors for perimeter monitoring. A single light path will replace many point sensors. With GasFinder2 perimeter monitoring, all gas dispersed from a facility is detected and logged.

For Sports Facilities

Precision mass flow control with industry leading pressure drop of 4.5 psid (310 mBard) up to flows of 500 slpm (nlpm); Accuracy +/- 1.0% of full scale; 316 stainless steel construction; CE Approved

Wind Farm Noise Assessment by XL2

by NTi Audio AG     based in Schaan, LIECHTENSTEIN

One of the largest acoustic consulting firms in Australia was engaged by the New South Wales Department of Planning & Industry to conduct wind farm noise assessments. The goal was to perform a specialist, independent acoustic compliance audit of three major wind farms located near Canberra, Australia’s capital city. The objective of the study was to conduct a detailed noise assessment at residential dwellings near to the wind farms. Three wind farms near Canberra, Australia, were investigated. XL2 Sound Level Meters were operated on a continuous basis, typically over a six week period at each wind farm. The XL2 was battery powered to enable continuous noise logging for two weeks at a time at each residential site. The recorded data was then processed in accordance with the relevant standards specified in the conditions of consent for wind farms.

Air monitoring equipments for outdoor & indoor air quality

by Gradko International Ltd     based in Winchester, UNITED KINGDOM

Gradko’s ambient air monitoring equipment is widely used to monitor both indoor and outdoor air quality. Continuous development allows us to provide equipment for a broad range of applications, covering short-term and long-term monitoring. Pollutants can be detected even at very low levels – limits of detection are typically in the low parts per billion (ppb) range.

Environmental Monitoring

by MicruX Technologies     based in Oviedo, SPAIN

Environmental monitoring is becoming more important every day in local, national and international policies, showing the environmental awareness demanded by society.

This fact gives rise to an increase in the amount of legislation that obliges companies to law enforcement. Thus, the necessity of making more pollutants controls means high analysis expenses to the companies, which need to subcontract this service.

Although applications in this area advance, there is still a clear demand to get new portable and versatile analysis systems for many different application fields such as pollution in environmental or waste waters, monitoring nutrients in agricultural or horticultural water as well as general process control in chemistry industry. Because of the number of enviromental analysis required, there is a need for screening and monitoring measurements of these compounds at contaminated areas.

Traditional monitoring techniques are typically based on laboratory analysis of field-collected samples that require considerable effort and expense, and the sample may change before analysis. Moreover, the equipment currently available is too large and expensive and it cannot be made portable.Alternatively, microfluidic and electrochemical sensor technologies can contribute to the development of new portable monitoring systems, complementing standard analytical methods for different environmental monitoring applications.In this way, the decentralization and integration of all those typical analyses is the paramount importance in order to reduce cost, simplify the analytical process and make more accessible these technologies to end-users. The development of portable, robust, and accurate Lab-on-a-Chip systems to monitor priority compounds such as contaminants, explosives, chemical warfare agents, inorganic and organic ions is a demand of modern society. Portability allows analyses to be carried out outside of the laboratory, minimizing the risk of contaminating the sample and leading to a faster response time at a lower cost.

Thus, MicruX solutions and technologies open the gate to develop portable and esay-handly Lab-on-a-Chip devices in order to improve pollutants in-situ analysis in a very economic and efficient way.

HCl Monitoring in Air

by Unisearch Associates Inc.     based in Concord, ONTARIO (CANADA)

Hydrogen chloride (HCl) is a colorless, sometimes slightly yellow, gas. It is an undesired environmental component that may be damaging to workers and the surroundings. Exposure limits have thus been established by industries to make sure that the workers operate in a safe environment. HCl monitoring is especially required for incinerators, coal-fired power plants, aluminum recycling and cement plants. Unisearch offers a reliable and easy-to-use HCl analyzer – the TDLAS-based LasIR system. Studies have shown that TDLAS equipment provides data that is more accurate than conventional gas monitoring equipment. When calibrated for HCl monitoring, TDLAS is able to detect this gas among other gases present in the area and provide continuous updates with regards to the changes in its concentration.

Haze Monitoring

by Ecotech Pty Ltd     based in Knoxfield, AUSTRALIA

The principle cause of regional and urban haze, or visibility impairment, is light extinction caused by fine particles, sulfates, organic and elemental carbon, nitrates and crustal matter. Particles between 0.1 and one micrometers in size are most effective at scattering light, in addition to being of greatest concern for human health.
