  1. ECE5320 MechatronicsAssignment#01: Literature Survey on Sensors and Actuators Topic: pressure sensor Prepared by: Beau Griffiths Dept. of Electrical and Computer Engineering Utah State University E:beaug@cc.usu.edu ; T: (435)797-1000; F: (435)797-3054 (ECE Dept.)

  2. Outline • Reference list • To probe further • Major applications • Basic working principle • A typical sample configuration in application • Major specifications • Limitations ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  3. Reference list • http://everything2.com/e2node/magnetic%2520torquer • http://en.wikipedia.org/wiki/Pressure_sensor • http://citeseer.ist.psu.edu/context/846402/0 ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  4. To explore further (survival pointers of web references etc) • http://citeseer.ist.psu.edu/context/846402/0 ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  5. Major applications Magnetic Torquers are used in the field of Spacecraft Attitude Control ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  6. Basic working principle Running electric current through a coil produces a magnetic field that is able to react with the magnetic field of the earth. The torque generated is used to control the attitude of the spacecraft. The only alternative in spacecraft attitude control is in mass ejection (rocket thrusters) and momentum wheels. ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  7. sample configuration ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  8. Limitations • torques can only be produced perpendicular to the magnetic field • A magnetic field must be present, thus useless for deeper space travel ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators

  9. Major Specifications Magnetic Dipole Moment (A*m^2) Weight Size Power Consumption Interface ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuators
