Magnetic Field Wireless Sensor

Measuring range: ±5 mT and ±130 mT.

Magnetic Field Wireless Sensor



I. Working principle

The sensor uses a Hall effect converter, which can output a voltage that is linearly related to the magnetic induction intensity of the magnetic field. The housing of the sensor probe is made of plastic, and the probe measures the axial component of the magnetic field in the plastic tube. When there is no magnetic field in this direction, the voltage value output by the sensor is 2.5V (corresponding to 0 mT).

II. Specifications

Measuring range: ±5 mT and ±130 mT.

  6. The sensor terminal is designed with a hidden buckle sensor interface to support combined experiments with other sensors.
  7. The sensor terminal has designed a fixation spot to get itfixed on the iron frameconveniently and combined with traditional lab equipment for experiments.
  8. The sensor terminal supports the latest operating systems,such as iOS, Android, windows operating systems, etc.

IV.Typical applications

The magnetic induction sensor is a sensor that measures the magnetic field in space. It is often used to measure the magnetic field near permanent magnets and inside energized solenoids. It can not only measure the magnitude of the magnetic induction intensity, but also roughly determine the direction of the magnetic induction intensity. Its typical applications are: measuring the geomagnetic field intensity, research on strong magnetic fields, the relationship between the magnetic induction intensity and current of energized solenoids, etc.

VI.Usage Tips

  1. Software regulations: When the probe tube of the sensor moves to the N pole of the magnetic field, the reading is negative; when it moves to the S pole of the magnetic field, the reading is positive;
  2. The absolute value of the reading is the magnetic intensity component of the measuring point in the direction parallel to the probe tube;
  3. When using, the interference of the external magnetic field on the sensor should be minimized.
