DT028-1 Sensor Sheet

Type:
Magnetic Field Sensor

Radial, Axial Range:
±2000 Gauss

Sensor Description:

The Magnetic Field sensor is a device to measure the magnetic field (e.g. near a permanent magnet, current-carrying wire etc.).

How it works:

The sensor uses two Hall effect transducer located in a 90° angle between their sensitive elements. The Hall effect sensor is producing a voltage, which is linear with the magnetic field. The sensor measures the component of the magnetic that is parallel or perpendicular to the plastic pipe. When no magnetic field is present, the sensor should read 2.5 Volts (0 Gauss), which is called the offset voltage. A magnetic field will cause the voltage to increase or decrease, depending on the direction of the magnetic field. One can measure either Radial or Axial magnetic fields while rotating of the switch on the side of the plastic pipe.

Definition and Calibration of this Sensor:

In case the sensor is not already included in the DBLab sensor list, you' have to define two sensors through the DBLab interface (one for high and for low amplification).
Define first the sensor for Axial field:
1. Open Logger >> Define Custom Sensor, a dialog box opens.
2. Select one of the 10 already defined sensors within the listbox.
3. Overwrite the given name under Sensor Name with the name of your sensor (e.g. Magnet_h)
    and define the name of the unitname (e.g. gau for Gauss).
4. Enter '0' under Volts for Value#1. Enter '-2000' under Measured Unit.
5. Enter '5' under Volts for Value#2. Enter '+2000' under Measured Unit.
6. Press OK; the dialog box closes.

What is it used for:

The Magnetic Field sensor can be used for a variety of interesting experiments like studying the magnetic field near a permanent magnet, near a current-carrying wire or at the opening of a solenoid.
