Yokogawa buys TruePeak manufacturer

14 April 2008

Following its acquisition of Analytical Specialities Inc. (ASI), Yokogawa Electric Corporation has boosted its analyser line-up with the addition of TruePeak Tunable Diode Laser Gas analysers. Yokogawa said the purchase of the Texas based company, on April 1, 2008 provided it with a ‘unique’ technology.

Tunable Diode Laser Spectroscopy (TDLS) technology is used in industry for purposes such as measuring oxygen and carbon monoxide concentrations for combustion control, detecting ammonia and hydrochloric acid in exhaust gas, and monitoring moisture levels in natural gas pipelines. These gases absorb infrared light at specific wavelengths unique to each gas, and their concentrations can be measured by illuminating them with a laser and analysing the absorbed wavelength in the spectrum of the transmitted light.

‘TDLS enables the direct high-speed measurement of many important process gases, including combustion by-products, impurities and oxygen in many chemical and refining operations.

‘ASI’s TruePeak TDLS analyser utilises a very promising and proprietary peak area integration method that offers both high measurement accuracy and repeatability compared to other commonly used products,’ said Trevor Knittel, president of ASI.

Yokogawa says it will establish a Laser Analytical Division within its US subsidiary as a core unit for the industrial automation environmental and measurement business.

Satoru Kurosu, senior vice president of Yokogawa’s Industrial Automation Business Headquarters, said: ‘To achieve the top position in the global industrial automation market by 2010, Yokogawa has announced its VigilantPlant solution portfolio.

‘We consider that technologies and products focusing on energy focusing on energy saving and environmental conservation will continue to enhance our capability to offer solutions over the entire lifecycle of a plant that also address the need for energy saving and environmental conservation.’
