Magnetic Field Sensor ±2000 mT 1009941
Instruction Sheet
04/12 Hh
1. Description
Sensor box with attached sensor probe, 140
mm long, 7 mm wide and 1.9 mm thick, for
measuring magnetic flux density B of a mag-
netic field acting outside the box in a tangential
plane, primarily for use with the basic Hall-
effect apparatus (1009934).
At the tip of the probe there is a Hall sensor
with an active area of about 0.044 mm², which
produces a steady output signal that is rati-
ometric (i.e., proportional to the operating volt-
age).
The Hall sensor has an extended temperature
range of -20°C to +180°C for measuring the flux
density of heated germanium semiconductor
crystals (probes).
There are two latching range buttons for 0.2 T
and 2 T plus an additional Tare button for cali-
bration. The current setting of the measure-
ment 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.
The box is also suitable for use with the connec-
tor box (115 V, 50/60 Hz) (1009954) or connector
box (230 V, 50/60 Hz) (1009955). See the rele-
vant technical data.
2. Safety instructions
The magnetic field sensor is not suitable for
applications where safety is essential.
