Magnetic field amplitude measurement
Generating magnetic field amplitude variation as a linear function of the position
MMT has developed a complete family of magnetic circuit to generate a magnetic field amplitude variation as a linear function of a permanent magnet position. In association with the most recent field amplitude measurement Hall ASIC, these magnetic structures ensure the following performances:
- Non linearity below +/-1% of the stroke on the automotive -40°C to 150°C temperature range
- Low sensitivity to production and application tolerances (off centering in all axes) as well as external disruption (magnetic field, magnetic particles...)
- Programmable through the connector (gain, offset, temperature compensation)
- Rotary stroke from 2° to 160°
- Linear stroke from 1 mm
- Custom features available on request
