High temperature protection is provided in the form of cooling coils. These devices prevent the pressure spike from reaching the sensor. Another concern is vibration, which can be handled through proper mounting technique of both the sensor, the control unit, and the electronics. Remote mounting of as much of the devices components as possible will minimize most of the vibration situation. Reference Sensor, April 1997.
Magnetic fluids are suspensions of micron size iron particles.
When a DC electromagnetic field is applied the material stiffens directly proportional to the magnetic field strength. When the magnetic field is removed the material returns to a viscous liquid. The dimensions are 1.5 inch thickness and 3.6 inch. Heat dissipation is 750 watts in the stepper and 500 watts in the bike. A new application of magnetic fluid is for optical lens finishing.
