The BOS FiberSense 4mm sensor is designed for 1/4 inch slip stream measurement applications. The 4mm wand-style optical oxygen sensor offers high precision in a small package. Historically used with 4401OXY and now utilized with OXYvisor for special cases in place of our most standard and common FlexSense II.
The small sensing tip can be installed directly into a tube fittings which makes it the ideal choice for oxygen measurement on sample line installations. The fiber optic tip is encased in a stainless steel wand and can be supplied bare or with optional armored conduit (figure 5 & 6). The BOS FiberSense product is commonly used in gas phase sample line installations. An external temperature sensor is required for compensation.
The sensor tip can be installed through a traditional tubing compression fitting. Each oxygen sensor can be ordered with or without armored flexible conduit.
