New Portable Echo Repeater System
Chelsea Technologies Group (CTG) won a tender from an American company for a portable echo repeater system, with a further system going to Singapore next year. This new system is a miniature version of CTG’s flagship towed sonar test and evaluation system, VASS (Versatile Acoustic Source System). A new low frequency hand-deployable acoustic transducer will be employed along with a portable ...

NivuFLow 650 - Intuitive Operation and a wide Range of Sensors
The new transmitter has been developed for accurate flow measurement in open channels, part full and full pipes, and surface water bodies and is compliant with both ISO 6416 & IEC 60041. To meet the highest possible accuracy requirements it is currently possible to utilise the NivuFlow 650 using up to 4 velocity paths, with up to 32 velocity paths available by the end of 2016. It is then ...

Chelsea`s hydrophone arrays are being used by the NTNU to study the reactions of fish to sound
“Chelsea has been working with the Norwegian University of Science and Technology (NTNU) for a number of years”, said Chelsea’s acoustics specialist Paul Bolton, “they initially commissioned us to custom design a 6m vertical acoustic hydrophone array in order to conduct novel underwater acoustic experiments. This was followed by the design of three 8m long, active ...

Noise measurement in the refuse and recycling sector – the shattering reality!
The ability for a local authority to provide an efficient and effective refuse and recycling service is pivotal for both residents and the upkeep of the surrounding environment. However with the increased noise levels that new recycling initiatives generate it is imperative that the welfare of operatives working in this sector is looked after rigorously. David Wilford of No Going Back ...

NOVEL SENSORS AID TIDAL TURBINE DEVELOPMENT
Non-contact torque sensors from Sensor Technology are playing a key role in the development of commercial-scale in-stream tidal turbines produced by Irish company, OpenHydro. The company is using these novel sensors, which are based on surface acoustic wave (SAW) technology, to accurately measure rotational speed and frictional forces in a simulator for the turbine bearings, thereby allowing it ...

Ground Crews Talk Sense On Generator Maintenance
Aircraft servicing times are being reduced, enabling more flying hours, thanks to a new fully automatic generator testing station developed by MEL Aviation in Sudbury, Suffolk. A key element in the design of the station is the use of a TorqSense non-contact torque sensor, which can be deployed instantly for high performance acceleration and deceleration tests of aircrafts’ generators. ...

Servo research points the way to improved dynamics
Research at the University of Manchester has demonstrated servo systems with vastly improved dynamics with the most challenging of loads. The key to the increased performance is a torque transducer from Sensor Technology employing Surface Acoustic Wave (SAW) techniques to deliver high-bandwidth, non-contact solution.The ease of set-up of modern servo drive systems, combined with steadily reducing ...

Pulsar’s Ultrasonic Success with Super-light Fumed Silica Measurement
Fumed Silica has a bulk density of around 30g/l, and a surface area of sometimes hundreds of square metres per gram. It is used as a thickening agent in everything from gel batteries to non-drip paint, as a light-scattering agent in cosmetics and a toothpaste abrasive. However, a material as light as this presents significant difficulties in bulk measurement. After a number of failed attempts, ...
