Extended Industrial Safety Range with New Six New Gas Sensors
Honeywell company, City Technology (UK), the World’s leading manufacturer of gas sensors for industrial safety and emissions applications, has added six new sensors to its electrochemical sensor range. The 5OxLL long life oxygen (O2) and A5F+ carbon monoxide (CO) sensors extend the 5 Series range - widely used by high specification flue gas analyser manufacturers globally requiring EN 50379-2 compliance. The new 4 Series range includes the 4OxLL long life O2, 4OXV O2, 4F and 4MF CO sensors - designed for use with EN50379-3 compliant analysers.
Emissions gas sensing for domestic and light commercial boiler combustion analysis can be a challenge. Sensors are subjected to high humidity, temperature changes, corrosive and acidic gases which can cause field failures and measurement inaccuracies - compromising performance and stability and increasing servicing/calibration needs. A suitable sensor should be built to a high specification and from resistant materials that enable them to withstand these conditions. Added to this is the ever-present need to reduce operational costs. With much focus on the specification of the analyser itself, it is essential to remember that an analyser is only as good as its sensors.
The new 5OxLL long life O2 sensor is RoHS compliant and designed to operate for the whole life of the analyser. It reduces the cost of ownership and field failures through enhanced stability, and enables analyser manufacturers to reduce servicing costs. 5OxLL’s impressive longevity is achieved by its “electrochemical pump” technology, removing the need for a
consumable lead anode; the life limiting component in today’s comparable sensors.
The new A5F+ CO sensor is ideal for “high range” applications (up to 20,000ppm) which traditionally require a second sensor to meet EN50379-2. A5F+’s robust and advanced design is H2 compensated and also includes high capacity filter to achieve reliability and extend operational life (5 years).
City Technology’s new compact 4 Series sensors include the 4OXV O2 sensor, with a 2 year life and the 4OxLL long life O2 sensor – designed to match the lifetime of the average analyser. This new range also includes the 4F and 4MF CO sensors, offering low and high range measurements; 4F (0-20,000ppm) and 4MF (0-100,000ppm). Both sensors include robust internal acid gas filters to ensure operational life in demanding emissions environments.
Tom Gurd, Product Marketing Manager for City Technology comments: “The addition of our new premium 5 Series sensors, designed for high-end analytical flue gas analysers and the new 4 Series emissions sensors for combustion efficiency instruments used in installation and service applications, extend our market leading portfolio. These products respond to key market drivers such as benchmark compliance, enhanced sensor reliability and reduced cost to serve. With over 25 years’ emissions sensing expertise, we have considerable knowledge of core market needs and what today’s equipment manufacturers and end users demand.
“These six new sensors use advanced component design, ultra-resistant materials, high activity electrodes and high capacity filters ensuring repeatability, stability and accuracy as well as fastest response times. They also help businesses leverage sizeable operational efficiencies by reducing measurement time and service time.”

Wireless Version of Transportable Gas Detector Announced
Oldham (France), an IST Company, is very pleased to announce the launch of the exciting wireless version of the five- sensor transportable gas detector, the BM 25. As wireless capabilities reach new technological milestones, the integration of wireless gas detection systems in industrial applications is ever increasing.
The network topology used by the BM 25 is a MESH network. In a mesh network all hosts are connected peer-to-peer without central hierarchy, thereby forming a net-like structure. Each node can receive, send and relay data and this avoids having sensitive points, which in case of failure, disrupts
the connection of the network. If a node is down,
it simply goes through another route. Mesh topology allows fast and simple deployment, high coverage versatility and high fault tolerance. It significantly reduces installation and operating costs of networks.
If a BM 25 does not respond to network communication requests, the local gas detection capability remains effective and each BM 25 will provide local alarm capability in the presence of gas.
If the network is split due to an obstacle placed in the network, it is possible to continue to work as the network will automatically adjust and form two separate networks. When the obstacle is gone, the communication resumes automatically.

Dräger Marine & Offshore (Germany), part of the Dräger Group, is helping to improve Asset integrity management for offshore oil and gas operators with its thermal imaging technology.Dräger’s equipment is currently being used to detect ‘hotspots’ prior to maintenance and repair work offshore, providing oil operators with a quick and easy solution to check for potential problems before implementation of a repair or strengthening plan, leading to reduced downtime.
Safety is a number one priority for Dräger and its advanced thermal imaging technology is already used by firefighters globally, as part of Dräger’s larger firefighting equipment portfolio
for many applications including search and rescue, so this development takes its use one step further with offshore applications which have a direct effect on improving safety and efficiency. Phil Saxton, general manager for Dräger Marine & Offshore Aberdeen, said: “It’s 25 years since the world’s worst offshore oil disaster, Piper Alpha, and while lessons have been learned, Dräger is going one step further with its preventative measures to ensure continuous improvement in offshore safety standards.He added: “Sometimes hotspots are not immediately apparent to the naked eye, the planning and execution of maintenance work can be highly targeted through identifying such areas of concern.” Its offshore benefits were initially discovered by Denmark-based Dräger Safety Key Account Manager, Peter Sonne, and an international oil giant which led to an initial order being placed six months ago. Peter said: “It is great news and a key development in the progression of how Dräger is working with its customers to deliver the best solutions offshore.
“The discovery was made during a meeting at a customer site last year when I used a thermal imaging device to detect the fill level of a tank. Together we realised there was potential for using this kind of device in difficult to reach and hazardous locations offshore and the customer therefore placed an order.
“Since then, the customer has seen substantial benefits in applying Dräger’s technology on its North Sea oil platforms. The equipment is being used to detect potential overheated connections, fire or loose connections in electrical installations and issues can be identified early to prevent costly downtime and save companies substantial amounts of money. Peter added, “It’s great when just through talking to our customers we can help them identify ways to reduce costs and be safer. Asset Management is just one area Dräger is keen to support with a wide range of products and services including the on-going supply and servicing of all Fire, Rescue and Safety equipment and varied offshore focused training courses, the use of thermal imaging, just answers another challenge for the customer.” Dräger’s thermal imaging cameras have the advantage of being Atex-approved too, which means they can be used in explosive environments – something that is extremely useful in a hazardous area like an oil platform. The cameras rely on heat signatures and can see in darkness, fog or smoke and even minor temperature differences are visible due to a difference in thermal characteristics. The camera is also capable of capturing video and photographs of displayed thermal images. Video and photos can be downloaded for documentation.
