Magnetic Field Sensor, Tangential U11360
Instruction Sheet
01/08 Hh
1. Safety instructions
•
To avoid permanent damage to the Hall sensor
in the sensor probe tip, do not subject it to any
mechanical pressure!
•
Do not bend the sensor probe tip!
•
Only use the magnetic field sensor for educa-
tional purposes!
It is not suitable for safety-related applications!
2. Description
Sensor box with attached sensor probe, 140 mm
long, 8 mm wide and 1.2 mm thick, for the meas-
urement of magnetic flux density B.
At the tip of the probe there is a Hall sensor with
an active area of about 0.5 mm², which produces a
steady output signal that is ratiometric (i.e., pro-
portional to the operating voltage).
Three buttons allow one to choose between meas-
urement ranges of 2 mT, 20 mT or 100 mT, with a
locking facility. The current setting of the meas-
urement range is shown visually by a light-emitting
diode on the left of the relevant button.
The stand clamping rod can be adjusted to hold
the sensor in the desired position and orientation
in the magnetic field that is being measured.
