The M4/P4 series of infrared gas detection sensors utilise NDIR (Non Dispersive Infrared) to monitor the presence of Methane CH4 or Propane C3H8, and general hydrocarbons (cross-reference of other hydrocarbon gases measurable with these sensors is available on request) .
This technique is based on the fact that the gas has an unique and well defined light absorption curve in the infrared spectrum that can be used to identify the specific gas. The gas concentration can be determined by using a suitable infrared source and analysing the optical absorption of the light that passes through the gas.
The sensor contains optics and incorporated electronics with software in order to provide an output that is linearised and temperature compensated. The type of output can be of analogue voltage type [0.4 V—2 V] dc (other voltages, falling or rising, are available on request) or bridge type [Vcc/2 ± Δ)] dc (falling or rising and Δ value is to be specified by the customer) depending on the sensor model.
The sensor provides a linearised and temperature compensated analogue voltage output (voltage or dynamic pellistor) that is proportional to the gas concentration.
