Designed for long-term continuous sensing of CO2 and numerous hydrocarbon gases including vapours in fixed systems, e2v (UK) IR sensors are suited for portable instrumentation where shorter term usage is more usual.
The metal-mesh gas entrance aperture is also flame arresting and the whole body structure is explosion proof to ATEX, CSA and UL standards. The series-4 size provides compatibility with other electrochemical and catalytic sensors in multi-gas instrumentation. Our twin gas sensors have two active gas channels for simultaneous detection of carbon dioxide and methane (or other hydrocarbons).
Electrochemical Gas Sensors
Designed for monitoring a range of toxic gases in the ppm range at occupational exposure levels, these sensors are used both in fixed and portable instrumentation. In addition a sensor is available to measure Oxygen in % levels for safety applications.
These sensors detect gas by measuring the current produced when the target gas undergoes a chemical reaction (reduction or oxidation) inside the sensor. The current produced is proportional to the concentration of the target gas.
Metal Oxide Semiconductors
e2v has a proprietary MOS technology utilizing state of the art MEMS technology, combining a specialized nano-partical sensing layer with a patented poly-silicone heater.
This unique design creates a highly sensitive and responsive semiconductor sensor, manufactured on an automotive production line for outstanding quality and performance. These sensors are easily capable to detect and measure combustible and pollution gasses in parts per billion (PPB) and are suitable for many environmental, automotive and industrial applications worldwide.
