Light Sensor U11364
Instruction Sheet
02/08 Hh
1. Safety instructions
The light sensor must only be used for educational
purposes!
• The light sensor is not suitable for safety-
related applications!
2. Description
Sensor box incorporating photodiode with optical
filter for the measurement of light intensity (illu-
minance), especially in the visible region.
Push-button selection of measurement ranges 600
lx, 6000 lx or 150000 lx, with visual indication of
range.
8 mm light tube for excluding unwanted light from
sides.
The sensor box and range setting are recognised
automatically by the 3B NETlog
TM .
3. Equipment supplied
1 Sensor box
1 Stand with screw thread, 120 mm
1 miniDIN 8-pin connecting cable, 600 mm long
1 Instruction sheet for U11364
4. Technical data
Measurement ranges 0 to 600 lx / 0.8 lx
and resolution 0 to 6000 lx / 8 lx
0 to 150000 lx / 200 lx
Sensor type: Silicon photodiode with
low dark current
Sensitivity: Typically 0.65 µA at 100
lx
Non-linearity: Max. ±1 % of the total
measurement range
Bandwidth: Typically 10 kHz
5. Operation
• Place the sensor box close to the experiment.
• Read off the light intensity value on the display
of the 3B NETlog
TM .
• If the light intensity exceeds the measurement
range, switch to the next higher range.
