The Otis Instruments OI-501 Remote Sensor Kit allows you to separate the sensor housing from the Otis sensor assembly in order to monitor hard to reach areas while still allowing easy access to the control board for maintenance and configuration tasks.

The OI-501 is compatible with the OI-6000, OI-6400, OI-6900, and OI-6940 to extend the sensor housing. The OI-501 is available in both non-explosion-proof and explosion-proof varieties which allows it to be installed in any environment.
