Unique technology from Delsbo saves lives in China’s coalmines

Unique technology from Delsbo saves lives in China’s coalmines

31 May 2013

SenseAir, in cooperation with Fiber Optic Valley and Acreo Swedish ICT, are running a multimillion-dollar project aimed at developing a new methane sensor – a new product that could mean more jobs for the Hudiksvall area. The product’s main market is the thousands of Chinese coalmines where the sensor will be used to ensure safe working conditions for the miners. The aim is to bring the product to market by the end of 2013.

− During the past year we have been working very closely with the end customer in China; among other things, we have been on a visit down a mine in China in order to gain an understanding of the demands to be met in the handling of the sensor, and also the environment in which it must function. Already today we can see that this is a new expanding market for us at SenseAir, says Christer Engnér, CEO at SenseAir.

– The product provides a good example of how innovation is created when organizations work together, says Jonas Dahlström, CEO at Fiber Optic Valley. The investment involves recruiting first-rate competence to the project, and in the long run can also mean more jobs for our region.

About the project

The project is called “new methane sensor with IR optic measurement cell” and is concerned with improving safety for miners and also avoiding unnecessary shutdowns. Methane commonly occurs in coalmines, and is a cause of both shutdowns and accidents. Pockets of methane are trapped in the coal seams and released into the working environment during mining. Gas concentrations can become so high that they exceed the explosive level with disastrous results. As in most countries, there is legislation in China that requires all mines to be equipped with sensors that can detect high levels of methane. The product is clearly superior to traditional technology and has an obvious competitive advantage in calibration, accuracy and quality.
