NDIR: Origin of NonLinearity and SPAN Alphasense

Email: sensors – Web site: NDIR: Origin of NonLinearity and SPAN The dual channel detector in an NDIR sensor consists of two filter windows. The active filter is centred on an infrared absorption peak of the target molecule and the reference window is in a portion of the infrared spectrum where there are no absorption bands. Although the active filter is ...

Why LMP91051 cannot be used for Alphasense NDIR IRCA1 ...

20210720· I am working on to build my readout circuit for Alphasense NDIR IRCA1 CO2 sensor. I found one posting saying that. The thermopile output stage generates a voltage with a very low impedance (like a battery), while the Pyro detector output stage generates a voltage with high impedance so the LMP9105x is not well suited for pyroelectric detectors.

Alphasense Application Note AAN 20106 NDIR: Gas ...

What is an NDIR Sensor? Alphasense IRCA sensors use the principle of NonDispersive InfraRed (NDIR) to determine gas concentration. Each sensor consists of an infrared source, optical cavity, dual channel detector and internal thermistor. Gas diffuses into the optical cavity. Light from the infrared source passes through the optical cavity where it interacts with the gas before impinging on ...
