Appendix 5 Mechanical Design of Optode 4835

Refer Figure 1-3 and Figure A 8 for illustration of the Oxygen Optode 4835. A cylindrical polymer housing
shields the electronics from the surrounding water (pressure rated to 300 m).
A 4mm thick sapphire window provides the optical connection between the optics inside the Optode and
the sensing foil on the outside. The foil is fixed to the window by a POM securing plate and is easily
replaceable.
A 10-pin receptacle in the sensor foot provides all electrical connection to the sensor. To prevent potential
leakage from the sensor to the rest of the measurement system, the receptacle is moulded inside a
receptacle housing.
Refer CHAPTER 6 for instructions concerning changing the Sensing Foil.
Note! The sensor should not be opened! Opening the sensor housing can breach the warranty (ref.
CHAPTER 6 , page 39 for instructions on how to change the Sensing Foil).
