The Magnetic field sensor BT52i contains a Hall-element, which is sensitive to a magnetic field. It has two measurement ranges, which can be selected using a switch. The sensor is very suitable for measuring the magnetic field inside coils, or near (strong) permanent magnets.

Ranges: -10 ... +50 mT, -100 ... +500 mT
Resolution (12-bit): 0.024 mT, 0.24 mT

Can be used to:
• measure the magnetic field near a (strong) permanent magnet,
• investigate the magnetic field near a current-carrying wire,
• measure the magnetic field near or inside a coil or solenoid.
