Assignment#1 Survey on sensors and actuatorsSlide-5Major applications •Scientific Exploration- (ie presenting more information about aerospike rocket nozzles)•Altitude measurement•Control Systems- used as feedback sensor- possibly for water level in a tankBasic working principleAllowing pressure to work on an element can change electric properties such as resistivity or capacitance. A wheatstone bridge can be used to detect small changes in resistance.Mechanical deflection of a spring may also be used.01/14/19ECE5320 Mechatronics.

Assignment#1 Survey on sensors and actuatorsSlide-7Limitations•Temperature ranges: typical 0-130 or -40 to300•Pressure ranges: vac – 10,000 •Typically measures gas or air•Output in volt or current (can also be visual or auditory)01/14/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuatorsSlide-8Major SpecificationsPressure RangeOutput (volt, current, etc)Interface (PCB mount, Ribbon Cable, etc)Pressure TypeAbsolute – referenced against absolute zeroGauge – referenced against ambient pressureSealed – see level referenceDifferential – pressure difference between two inputs.01/14/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and actuatorsSlide-9Unconventional applicationSome car alarms use the cars speakers as pressure sensors. The pressure change due to window shattering is enough to induce a small current.01/14/19ECE5320 Mechatronics. Assignment#1 Survey on sensors and
