1 Product description
The DOL 16 is a sensor designed to measure light intensity. It is intended for application in livestock houses but
is also well suited for a number of industrial applications.
Two variants of the sensor are available; one with a cable, and one with M12-connector/cable.

2 Mounting
In dusty environments, the sensor should be placed in a position which allows for easy cleaning at regu-
lar intervals.
For optimum mounting of the sensor, use the mounting clip.
Mount the sensor in front of an inlet in the direction of the fresh air jet to ensure that the sensor is free from
dust. In houses with wall inlets place the sensor close to one of the inlets that opens first. I tunnel houses the
sensor must be placed minimum 20 meters away from the end of the tunnel opening to avoid light from outside
influencing the sensor.
The sensor should be placed in a position which is representative of the light level in the house - the light-sensi-
tive area of the sensor is shown in Figure 1.
Placement of the sensor where it is influenced by sunlight from the outside and objects obstructing light near
the sensor should be avoided.
Place the sensor in
front of an inlet that
opens first in order to
minimise the build-up
of dust on the sensor.

If ceiling mounting is not possible or not wanted, the sensor can be hung in the
cable 1-2 meters above the animals. If this type of mounting is used, the sensor
must be cleaned daily with a dry cloth.
When removing variant with M12 connector, the included plug must be mounted.

If 1:1 compliance with the L 182/19-standard is desired, measurements according to the standard and an adap-
tation to the output of the DOL 16 sensor with the chosen placement must be carried out.

6 Maintenance
It is important to keep the light-sensitive area of the sensor free of dust to ensure correct measurements.
See Figure 1.
Clean the sensor with water and a brush without using:
• High-pressure cleaner
• Highly compressed air
• Solvents
• Corrosive/caustic agents
• Alcohol-based disinfectants
During cleaning and disinfection, the sensor should be removed and the sealing
plug for the cable should be mounted.
Alternatively, the sensor protective cap can be mounted. The sensor must be
placed with the light sensitive area of the sensor upwards during disinfection.
Do not bend the sensor as this would inflict permanent damage on the electronics of the sensor.
