The GasSense NDIR gas sensor, with integrated transmitter, is an innovative measurement module for the detection of CO2, CO, N2O, CH4 or related hydrocarbons. The sensor can be easily integrated as an OEM component into controls, measurement systems and monitoring instruments.

The sensor uses dual channel Non-Dispersive Infrared Detection (NDIR) and detects the net increase or decrease of light that occurs at the wavelength where absorption of the detecting gas takes place. The light intensity is then correlated to gas concentrations.

To ensure a reliable and stable measurement, the module is temperature compensated. The gas cell has been designed using non-sequential ray tracing techniques in order to ensure the best compromise between accuracy and sensor dimensions. Additionally, a dedicated rugged gas sensor cell option is available to minimise corrosive effects in harsh industrial environments, like biogas applications. The GasSense electronic board features a native wireless module managed with Ultra Low Power techniques, a fault diagnostics system and a power module suited to manage charging and energy recovery systems. The GasSense sensor can be used with a pneumatic pump or can simply work by natural diffusion mode.
