Emerson’s engineers have created a sensing device capable of detecting gas leaks in bottles, cans and modified atmosphere packaging (MAP) at line speeds, using laser technology developed by Cascade Technologies, a Stirling, Scotland-based spinoff of the University of Strathclyde.
When Emerson acquired Cascade and its Quantum Cascade laser-based (QCL) gas analyzers and gas emission monitoring systems in 2014, Emerson found lots of applications for them in oil and gas, automotive testing, chemical processing and continuous emissions monitoring. In fact, according to Peter Watmough, global leak detection product manager, Emerson has shipped many hundreds of units to various markets, using more than 4,500 QCLs.
