CN0338 for R1234ze, R448A and R449A sensing


My name is Paul-Etienne Rétaux. I’m currently intern at HESION (78260 Achères, France).

I would like to use the CN0338 to sense the three following gases :

- R1234ze



Do you know, by any chance, the corresponding thermopiles to use in order to sense those three gases please ?

Thanking you in advance,

Best regards.

Paul-Etienne Rétaux.

    Hi Paul,

    Sorry for the delayed response here.  I don't know the corresponding thermopile part numbers for the gases.  For the CN0338 we used Thermopile sensors from Heinmann (HTS-E21-F3.91/F4.26 ), so I think if you took a look at the part number on their website you could most likely find other sensors targeted at other gases/wavelengths.  You'll need to double check to ensure the package style and number of leads match and that the operating ranges are similar so that the rest of the circuitry would work as well.
