DT028-1 Magnetic Field Sensor

DT156 Sensor Sheet

Type:
Magnetic Field Sensor

Radial, Axial Range:
±10 mT ±0..2 mT

Sensor Description:

The Magnetic Field sensor has two ranges. Low resolution range to explore the nature and strengths of magnetic fields of solenoids and permanent magnets and high resolution range to explore the Earth’s magnetic field.

How it works:

The sensor uses a Hall Effect transducer, which produces a voltage, which is proportional to the magnetic field. The sensor measures the axial component of the magnetic field (parallel to the sensor tube). The line mark at the front of the sensor indicates the exact location of the hall element.the side of the plastic pipe.

Definition and Calibration of this Sensor:

Selecting the range Flick the sensitivity switch on the top of the sensor tube to the desired range: High (±0.2 mT) or Low (±10 mT) Selecting units: The default unit is Tesla. To change the units to Gauss: 1. Click Setup Wizard on the main toolbar 2. Click Properties next to the magnetic field sensor input 3. Check the checkbox next to the desired unit to select it. 4. Click OK Calibration The DT156 ships fully calibrated. For further calibration an offset calibration screw is located at the top of the sensor tube. Place the sensor in a known magnetic field and start recording. Insert a flat screwdriver to the calibration hole and slowly turn the calibration screw until the reference value is reached.

What it is used for Measurement

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