The sensor with the c-shaped spot cap is self-draining in the recommended installation
angles and can therefore be used for hygienic applications.

Recommended installation angle
Possible installation angle
Inadmissible installation angle
The sensor with the u-shaped spot cap must be installed at an inclination angle of 0
to 180˚ in an assembly, holder or a corresponding process connection. Recommended
angle: 0 to 45° or 135 to 180 ° to prevent the attachment of air bubbles. At angles of
inclination of 45 to 135°, air bubbles at the oxygen-sensitive membrane may increase the
measured value.
Inclination angles other than those mentioned are not permitted. In order to avoid buildup
and condensation on the spot, do not install the COS81E-****U *** sensor upside down.
Follow the instructions for installing sensors in the Operating Instructions for the
assembly used.
5.1.3 Mounting location
1. Choose a mounting location that is easy to access.
2. Ensure that upright posts and assemblies are fully secured and vibration-free.
3. Choose a mounting location with an oxygen concentration that is typical for the
application.
5.2 Mounting the sensor
5.2.1 Measuring system
A complete measuring system comprises:
• a Memosens COS81E oxygen sensor
