Remote Sensor Option
It is often necessary to sample the combustible gas at
some distance from the gas sensor module. The IT Se-
ries enables the user to mount the sensor remotely from
the transmitter without the need for expensive and high-
maintenance sample pumps. The Remote Sensor Option
provides a separate gas sensor that can be mounted up
to 100 feet from the transmitter and connected via a
cable included.
