Mid-Range Gas Filter Correlation CO2 Analyzer
Model T360M
Teledyne Advanced Pollution Instrumentation
The Model T360M CO2 analyzer measures Carbon Dioxide by comparing infrared energy absorbed by a sample to that absorbed by a reference gas according to the Beer-Lambert law. Using a Gas Filter Correlation Wheel, a high-energy IR light source is alternately passed through a CO2 filled chamber and a chamber with no CO2 present. The light path then travels through the sample cell, which has a folded path of 1.28 meters.The energy loss through the sample cell is compared with the reference signal provided by the filter wheel to produce a signal proportional to concentration, with little effect from interfering gases within the sample. This design produces excellent zero and span stability and high signal to noise ratio, allowing excellent performance over a wide concentration range, making this instrument an ideal choice for CO2 reporting requirements associated with dilution CEMS.

Ground EMI Filters
High-frequency signals on ground is never good news - it interferes with normal operation of equipment and creates electrical overstress (EOS). However it is easy to block propagation of EMI on ground by installing highly-effective ground EMI filtes in ground lines. Our unique patent-pending ground EMI filters provide very low impedance for DC and mains' power while effectively blocking propagation of high-frequency currents throughout facility or equipment ground. Ground filters meet safety standards, as well as ANSI/ESD S6.1 and ANSI/ESD S20.20.

Band Pass Filters
VDI offers up-converter modules for communication applications. The double sideband nature of the up-converter modules makes filtering necessary. VDI has designed filters to filter one sideband and preserve signal modulation. These filters offer low passband insertion loss and high out-of-band rejection. Custom filters may be available upon request. NRE (non-recurring engineering) fee may be required.

Mid-Range Gas Filter Correlation CO2 Analyzer
Model N360M
Teledyne Advanced Pollution Instrumentation
The Model N360M measures carbon dioxide (CO2) by comparing infrared energy absorbed by a sample to that absorbed by a reference according to the Beer-Lambert law.The N360M uses Gas Filter Correlation (GFC) to overcome the interfering effects of various other gases (such as water vapor) that also absorb IR. The analyzer passes the IR beam through a spinning wheel made up of two separate chambers: one containing a high concentration of CO2 known as the reference, and the other containing a neutral gas known as the measure. The concentration of CO2 in the sample chamber is computed by taking the ratio of the instantaneous measure and reference values and then compensating the ratio for sample temperature and pressure. A nitrogen purge system is provided for the GFC wheel assembly to eliminate the effects of ambient CO2, if necessary.
