iv UK Focus - Air Monitoring Oxygen Gas Analyser with Proportional Flow Control Launched
In response to industry demand Cambridge Sensotec (UK) have developed the Rapidox 1100ZF-PFC Zirconia Oxygen Analyser, the company’s fi rst instrument capable of proportional fl ow control. This feature enables the control of oxygen in inert gas blanketing applications, for example inside an oven or similar equipment, via feedback between the analyser and valve.
Nitrogen, or other inert gases, are used within blanketing applications to protect against volatile substances, or substances that are prone to oxidation. Humid air in the head space of the container is replaced by the inert gas to secure against spoilage, combustion or explosion.
Wastage effi ciency and consistency are key factors throughout the process, alongside the necessity to maintain stable inert gas levels. Closed loop process controls systems help to control the variable factors that can have an adverse effect on the process.
The Rapidox 1100ZF-PFC analyser is ideal for such applications, as it will generate a control signal and output via auxiliary terminals on the rear panel. This signal is used to control the proportional gas valve on the external equipment. The incorporated Rapidox software uses established Proportional Integral Derivative (PID) control theory to enable stable control of the oxygen value.
The analyser possesses all of the distinguishing characteristics and features of the Rapidox 1100Z, including the provision of fast and accurate oxygen analysis over the range 1ppm to 100%. Response time is typically less than fi ve seconds for a 90% step change in gas compositions. An internal pressure sensor compensates for small changes in gas pressure in order to maintain stable readings.

28747pr@reply-direct.com The Remote Solution to Air Pollution
Environmental considerations are key requirements of construction projects, with clean air and reduced dust levels being of considerable important. Stroud based Enviro Technology Services plc, working in partnership with Dexdyne Ltd (UK) has introduced a new product that enables accurate and instant remote airborne dust monitoring - the Construction Dust Monitor (CDM).
A marriage of cutting edge laser dust scatter and web-enabled communications technology presents a unique and economical application which leads the way for effi cient remote monitoring of nuisance and potentially health damaging dust particles.
The web-enabled Remote Communications Terminal (RCT) accurately logs real-time dust particle concentrations and optional wind speed, wind direction and temperature. Data can be securely retrieved by any web-enabled device. Access is available at any time and from any global location allowing remote monitoring and control of activity at various sites.
The small, stand-alone monitor is designed for outdoors use. The recording unit has no moving parts, eliminating risk and mechanical failure. Its robust I/O board protects against external malfunctions. Electrical surges do not affect operation and its industrial grade communications technology guarantees data safety.
“We are excited to be collaborating with Enviro Technology Services to provide a system that allows real time monitoring whilst reducing the risk in the workplace in accordance with COSHH” says Bharat Gupta, Managing Director of Dexdyne.
The CDM remote air pollution application is a complete solution for construction, quarrying, aggregates and bulk-handling.
