The smaller sensor (FOP-3-3) has a polyimide protective sheath covering the pressure
transducer.
Cleaning the transducer end of the pressure sensor
The transducer is glued to the fiber, but it can be broken off if not handled carefully.
The sensor can not be mechanically cleaned by for instance rubbing with a tissue
soaked in alcohol. Instead the tip is cleaned by soaking in a solution of enzyme-active
detergent.
Clean the tip of the fiber optic pressure sensor as follows:
1. Make a fresh solution of 1 gm of Tergazyme powered detergent in 100cc of warm
water (<130 °F or 55 °C).
2. Soak the sensor tip for at least 10 minutes.
3. Rinse in water.
4. Dip in rubbing alcohol.
5. Store in the sensor storage case.
Caution: The transducer tip of the fiber optic pressure sensor
Cleaning the pressure sensor and extension cable SC male connectors
Clean the SC male connector ferrule end face before each use using the Fiber Optic
Connector Cleaner included in the Cleaning Kit (FOP-CLNKIT). Clean the end face as
follows:
1. Ensure a new cleaning surface by advancing cloth tape and tear off excess tape
as required.
2. Softly press the connector end face on the clean cloth tape and drag it across the
tape while rotating the connector.
3. Several connectors (<6) can be cleaned before advancing the tape.
Caution: The SC connector ferrule end face should be cleaned
Cleaning the SC female connectors
Clean the SC female connectors as follows:
1. Dip the tip of the cleaning stick included in the Cleaning Kit (FOP-CLNKIT) in
alcohol.

Refrain from applying mechanical
pressure to the transducer tip.
clean the sensor with mechanical pressure.
