Remote Sensor Option

It is often necessary to sample the combustible gas at some distance from the gas sensor module. The IT Series enables the user to mount the sensor remotely from the transmitter without the need for expensive and high-main- tenance sample pumps. The Remote Sensor Option (5394-

50)provides a separate gas sensor that can be mounted up to 100 feet from the transmitter and connected via a cable.

Maximum distance from sensor to transmitter: 100 feet
