Description
This intelligent compact oxygen transmitter uses proven zirconia or electrochemical technology for reliable oxygen concentration measurement. The zirconia sensor delivers fast response times and a long service life with low drift, whilst the electrochemical sensor allows measurement of background gases containing hydrocarbons. SenzTx is a low-maintenance oxygen transmitter that
is easy to integrate. It is a unique solution, delivering reliable performance in critical process applications.
