Installation and Wiring
Installation
• Select a measuring point where representative measurement can be taken.
Do not mount the sensor where medium flow is turbulent and fast-flowing.
• We recommend to fit the transmitter with a weather protection cover (see
"Accessories").
• Attach the sensor to a special extension tube. Due to the weight of the sensor
(approx. 5 kg), the sensor cable does not provide sufficient support. Never carry the
sensor by its cable.
• The best fixture is a pendulum frame which holds the sensor vibration-free.
• Install the system at an easily accessible position to prevent danger for the operating
personnel (during commissioning or when carrying out maintenance and cleaning
work).
• Route all cable connections to prevent mechanical damage and interference from
other lines.
• Install measuring channels of the sensor in the direction of flow to obtain a self-
cleaning effect.
• The activated sludge version of the sensor is equipped with a cleaning unit which
prevents soiling or blocking due to particles by compressed air. For other applications
with soiling contents, the cleaning unit is available as an accessory.
Install the air outflow of the cleaning unit at the narrow side of the light slit.
