Technical Product Specification - Ratings
Barben Oxygen Sensors (BOS), are sold separately or as parts of an integrated (SCP) package with the
OXYvisor
. The sensors consist of a fiber
optic cable with SMA termination at one end, for connection to the
OXYvisor
, and the other end, an oxygen sensing luminophore, to be placed into
the process or sample stream. For additional information on BOS sensors, please refer to the OXYvisor IOM, OXYvisor data sheet or BOSx Sensors
product data sheet. The BOSx oxygen sensors are shown on the installation control drawings.
