ndir co2 history

Nicera Philippines Inc.

Our NDIR CO2 sensor has a simple configuration with its infrared radiation source, cell, optical filter and infrared detection part. The optical filter to detect infrared is composed for 2 kinds of infrared wavelength. One is the wavelength band which is well absorbed by CO2, and the other is the wavelength band which is less affected by CO2 or other gas components. As it measures the ratio of ...

Non-Dispersive Infrared (NDIR) Gas Measurement: Past ...

devices were not available for utilization in NDIR gas sensors until the late 1950’s. • The first ever NDIR gas sensor for sale was the Beckman LB-I medical CO 2 analyzer in the early 1960’s for measuring end-tidal CO 2 levels for cardiac patients in hospital ICUs. • The Beckman LB-I was single-beam designed having a DC-operated

Nondispersive infrared sensor - Wikipedia

A nondispersive infrared sensor is a simple spectroscopic sensor often used as a gas detector. It is non-dispersive in the fact that no dispersive element is used to separate out the broadband light into a narrow spectrum suitable for gas sensing. The majority of NDIR sensors use a broadband lamp source and an optical filter to select a narrow band spectral region that overlaps with the absorption region of the gas of interest. In this context narrow may be 50-300nm bandwidth. Modern NDIR …

Carbon dioxide (CO ) measurement using Non-Dispersive ...

Non-Dispersive Infrared (NDIR) Spectroscopy . Non-Dispersive Infrared (NDIR) spectroscopy is a measurement technique used to non-invasively detect gas concentrations. Depending on their molecular composition, polyatomic gases possess the ability to absorb electromagnetic radiation at specific wavelengths in the infrared region. NDIR spectroscopy utilizes this ability to determine the measured gas

How does an NDIR CO2 Sensor Work? |

Small NDIR CO2 sensor breakthrough An engineering breakthrough occurred in 1993 when SenseAir AB patented a design for small-footprint CO2 sensors . These sensors solved the size problem by using folded optics and metalized molded plastic to reflect the light through a curved shape (referred to as a 'waveguide') that was longer than the footprint of the sensor module.
