Rated 5 out of 5 by from Plug and play thermocouple Pretty accurate thermocouple. Easy 2 wire connection. Would have been better if it mentioned somewhere the polarity of the colored wires.

Our application is to measure temperature up to 750 deg. C in a vessel filled with Hydrogen at 30 bar pressure. We are considering using: Item# NB1-CAIN-14U-12RP-TT36. Is it the correct choice ?

Asked by: ehud
Hi Ehud Thank you for the inquiry. This probe series is not pressure rated due to the temperature ranges it may be exposed to. Recommend a thermowell rated for high temperature hydrogen service for this application. Omega does not currently offer compatible thermowell. Please contact our temperature engineering for more details at TEMP@OMEGA.COM Best regards OMEGA
