56 Portable / Field Testing New Portable Noise Monitor Launched After 2 Years in the Making
Cirrus Environmental (UK) is leading the way in outdoor noise monitoring for 2014 with the launch of its new Invictus portable noise monitor. After more than 2 years in development the Invictus has been designed specifically for environmental noise applications with all new functions, making it the most comprehensive noise monitoring device on the market today.
Developed by Cirrus Environmental’s own in-house R&D team, the Invictus allows simultaneous measurements of all parameters and can be controlled remotely via 3G, GPRS, Wi-Fi Ethernet or Radio Modems. Its flexible programming allows the user to set different measurement periods and alerts for different times of the day/ different days of the week for a comprehensive system that meets every noise related challenge. It can also deliver its data with audio recordings, SMS, email and twitter alerts to ensure the information can be gathered and delivered virtually real time – ideal for site managers who need to be alerted to breaches of pre-set limits as soon as possible.
“We know from our research that the clients wanted a system that allows full integration of weather data and video recording systems so we included additional inputs and outputs specifically for this application,” added Justin Barker, Sales Manager from Cirrus Environmental. “The team also ensured that the Noise-Hub2 Software included allows the data to be downloaded, analysed and reports created easily and conveniently. It can run from a single
PC, server or accessed through a web interface so the data is accessible as soon as it’s recorded.”
Other extras introduced as standard include a new flexible calendar function that supports project planning needs. The calendar function allows different averaging periods and alerts to be set up for different times of the days/days of the week to comply with complex noise limit conditions, for example, if a project is working close to schools, public buildings or on festival sites.
“The Invictus includes the very latest technology available but is still easy to set up and deploy, concludes Justin. “It still offers a very wide range of parameters and the large colour touch screen gives access to the settings and configuration. It’s robust, reliable and we are delighted to launch it to market for 2014.”
As part of its client focused approach Cirrus Environmental also offers a 2 year warranty on the Invictus as well as full customer support via its training programmes, back up technical support, full maintenance and recalibration services.
Pressure Transmitters and Pressure Sensors Made of Corrosion-Proof Titanium

In 1795, German chemist Heinrich Klaproth was so impressed by the properties of a newly discovered element that he named it titanium, after the Titans (a Greek race of deities). The best-known Titan is Atlas, who was sentenced by Zeus to carry the world on his shoulders.
For some time now, Keller AG für Druckmesstechnik (Switzerland) has offered titanium versions of its products for use in heavily corrosive media. This metal has a host of advantages for applications under very special conditions.
Titanium is used as a replacement for steel in the aerospace industry, mainly for reasons of weight. In the medical devices sector, the fact that titanium is chemically and biologically neutral is especially
important. This property is due to a permanent layer of oxide on the surface of the material. Thanks to its presence, components made of titanium will not corrode even in salt water or chlorinated water, unlike the high-grade steels that are normally used in the sector. This is why
titanium is more frequently chosen for process measurement technology applications involving wastewater that may be contaminated with unknown corrosive substances. A titanium housing makes it possible to carry out hydrostatic level measurements effectively in brackish water, or even in iron chloride.
The development of an implantable sensor (Ø 9 mm) made of titanium has caused a sensation. If a sensor of this sort is made of steel, it can only be exposed to temperatures up to a maximum of 60 °C. At higher temperatures, the heat-induced expansion of the oil causes so much deformation of the steel diaphragm that it no longer returns to its original position. By contrast, the titanium diaphragm shows no deformation up to 120 °C, which also makes stability errors much less likely than in products with steel diaphragms. This is because the modulus of elasticity is only half as high. At Keller, titanium is increasingly used to manufacture high- quality transmitters that meet the most demanding stability requirements.
A Powerful Solution for Monitoring Soil Water Profiles

The PR2 Profile Probe, from Delta T Devices (UK), offers a highly convenient single instrument solution for accurate and concurrent measurement of soil water content at various depths down to one metre. The system offers two lengths of probe; the PR2/4, measuring at 4 depths down to 40 cm, or the PR2/6 measuring at 6 depths down to 100 cm. The PR2 system generates volumetric moisture content values at each of the sensor positions along the length of the Profile Probe.
The PR2 is built around patented sensing technology which provides research grade performance in all soil types - offering low salinity and temperature sensitivity. Installation is via a bespoke access tube - which is inserted into a pre-augered 27mm diameter hole in the soil. This results in minimal soil disturbance. Customised augering equipment is available to optimise installation.
The PR2 can be used in both portable and long term installation applications. A hand-held readout unit enables instant readings at multiple locations with a single probe. Alternatively, a
PR2 can be permanently installed for continuous monitoring with a data logger (such as the GP2 Data Logger and Controller).
The PR2 Profile Probe is a powerful research grade tool that can generate large amounts of accurate information quickly and easily. As such it has proved to have a wide range of applications in academic and industrial environments, from crop water balance and catchment scale studies to geotechnical, forest and viticulture applications. It has even been used to monitor relative changes in moisture content in stone walls.
The PR2 is small, lightweight, portable, and easy to use. It also has a unique ability to test the quality of the installation against the presence of stones or voids next to a sensor. This gives the operator the choice to re-site the access tube and probe if needed - to achieve optimum measuring conditions. Combined, these attributes have made the PR2 a first choice for many researchers who are looking for a reliable field-proven solution.

Avoid putting your employees’ hearing at risk and costly compensation claims by investing in the latest noise measurement technology from UK ‘s leading manufacturer while complying with the latest Noise at Work Regulations.
Loss of hearing can happen in a wide range of industries such as manufacturing but also in the entertainment, transport and construction industries. Recent court cases include an employee being exposed to excessive noise from machinery without hearing protection over a long period of time, resulting in permanently damaged hearing. Consequently, employers and safety practitioners have a duty to be well informed on how to manage this area effectively. This is to ensure that safety measures to identify the noise source and reduce noise exposure are in place in order to avoid both putting workers’ hearing at risk and costly compensation claims for noise-induced hearing loss. Some claims can reach thousands of pounds.
Pulsar Instruments Plc (UK) have 45 years’ experience in the field of acoustics and are experts when it comes to providing solutions to safety professionals for their occupational noise measurements. All Pulsar noise meters are designed to be simple to use and effective whilst complying with European standards.
The Yorkshire firm specialises in sound level meters to suit all budgets and applications. Pulsar Sound Level Meters and personal noise dosimeters allow users to make a representative measurement for each job function and establish accurately the exposure levels of noise.
Instruments are usually purchased as part of a complete noise measurement kit, containing everything required to carry out a compliant noise survey.
Any employer looking for affordable and practical solutions for workplace noise issues can invest in a Pulsar Instruments’ sound level meter at a very affordable price.
Pulsar Instruments are celebrating 45 years in business this year and will be exhibiting their entire product range at Safety & Health Expo at the Excel Centre in London – 17th-19th June – STAND T2100.
