Cambridge Insulating gas density sensor

Thanks to the wide variety of sensor technologies that can be used with this monitor, the OLCT100 fixed gas detector can detect a large range of gases. The combustible gases can be detected with a catalytic or infrared sensor, toxic gases with an electrochemical sensor, freons with a semiconductor sensor and carbon dioxide with an infrared sensor.

    Jun 30, 2016The sensor is a circuit loaded with carbon nanotubes, which are normally highly conductive but have been wrapped in an insulating material that keeps them in a highly resistive state. When exposed to certain toxic gases, the insulating material breaks apart, and the nanotubes become significantly more conductive.
