Magnetostriction

BHLT 1121 Series: The equipment is capable of taking measurements of magnetostriction on materials when exposed to DC magnetic fields. The equipment takes measurements at near DC frequency The equipment is PC based and operates on Windows7 platform. It uses monitor as output device while inputs are made through keyboard and mouse. Entire operation of the equipment is through mouse and keyboard. Plot of complete cycle of strain Vs magnetic field is measured and displayed. The system uses Electromagnet as a generator of magnetic field and strain gauge mounted on the sample under test generates signal that is further amplified and processed to study the magnetostriction. The system generates and controls the current in the electromagnet, measures magnetic field generated using Hall sensor kept close to sample under test and measures picks up signal from the strain gauge through the signal-processing unit
