drone inspection for gas detection

Gas sensors for the detection and monitoring of harmful substances within the environment such as carbon monoxide, carbon dioxide and methane are essential elements of environmental risk assessment. Used in a wide range of industries, processes

and applications they touch our every day lives, monitoring everything from toxins found in landfill and agriculture right down to modified atmosphere packaging. But what do you do when faced with monitoring gas levels in areas where no man should go? This is the issue which presented itself to Edinburgh Sensors’ clients, NTCR Consulting. NTCR are NASA contractors who specialise

in the field of harsh environment technology. Tasked with helping a customer conduct volcanic research they had to find a solution to help them navigate and conduct their research in an area which was difficult to access and inhospitable. A gas sensing drone was the answer. As an unmanned aerial vehicle (UAV), this provided a versatile solution to access this hazardous and potentially contaminated terrain.

With an emphasis on CO2, H2S and

SO2 a gas sensing drone was developed with enhancements including sensor

options for CH4 and O3. The device included one of Edinburgh’s Sensors own high

sensitivity laser diodes with the additional option of up to four electro-chemical sensors. The sensors can be customised to a variety of specifications for species and sensitivity ranges.

improving additive manUfactUring

Additive Manufacturing (AM) is revolutionising manufacturing. A growing number of high-tech organisations around the world are using AM technologies to use in applications ranging from product development to specialised manufacturing. Unfortunately, 3D printed parts sometimes suffer from low quality, which

is most often due to an unknown cause-and-effect relationship between a manufacturing process parameter, such as a polymer needing to be heated to a specific temperature, and process characteristics, such as part geometry and significant distortion as a result of cooling rate. Too often, process parameters are set using trial-and-error techniques, which are time- consuming, costly, highly subjective, and machine- and/or material-specific. FLIR Systems’ thermal cameras are proving their value in

advancing a wide range of emerging AM technologies by offering researchers and material scientists the accurate results needed to fine-tune materials, equipment, and process parameters while reducing development time and expenses. By studying the 3D printing process and its thermal properties with

thermal cameras, manufacturers have been able to make quick corrections with minimal production delays. Research grade thermal cameras, because of their high thermal

sensitivities and small spatial resolution capabilities, are able to monitor the effect of changes to 3D printer settings and base materials. And, because they offer non-contact temperature measurements of up to one million points in a single thermal image, these thermal cameras are capable of identifying sources of quality problems. 6

Edinburgh Sensors have a range of gas

sensors to suit a variety of gases. They can be integrated into a wide range of systems

for fast and reliable measurements of CO, CO2 and CH4. The company is able to provide bespoke solutions to meet research

and technical requirements suitable to a wider range of gases.

UK distribUtor gains fUrther gUildline instrUments territories

The team at UK- based Evolution Measurement are celebrating strengthening their relationship with partner Guildline Instruments after being awarded additional territories in Scandinavia and Finland.

Evolution Measurement currently supports the Canadian

Instrument manufacturer in the UK, Ireland, France, Austria, Germany and Switzerland. The additional territories clearly demonstrate Guildline Instruments’ confidence in Evolution Measurement. Guildline Instruments is an engineering company that designs,

manufactures and markets ultra-precise instruments for the fields of metrology and oceanography. Since 1957 their products have been used for research and as the primary instrument with respect to establishing traceability to fundamental electrical standards. Evolution Measurement’s managing director, Paul Crowhurst said:

“We have been working with the team at Guildline Instruments for just over two years. The quality and standard of product they produce is exceptional, which why we are able to confidently expand into new territories.” January 2019 Instrumentation Monthly
