Model OUSAF21 Sensor Installation
Figure 3.5: Recommended Orientation for Sensor Installation
Sensors can be installed either directly in a process line or in a by-pass line. They can be mounted either horizontally or at an angle.
If mounted horizontally, the sensor lamp and detector housings must be horizontal. This will insure that the optical window
surfaces are in a vertical position, which will help prevent build up on the window surfaces. The sensor should be located upstream
of pressure regulators. Operating sensors under pressure will help to avoid the possibility of air or gas bubble evolution, which can
cause measurement noise and error.
When installing, allow adequate space for the connection of cables at the ends of the lamp and detector housings. Access to these
areas is also important for connection/disconnection purposes. Sensor bodies should be supported when in line and care should be
taken to ensure they are protected against damage caused by external forces such as carts on adjacent walkways.
