CHAPTER 8 : DEVELOPMENT IN INSTRUMENTATION & MEASUREMENT
FOCUSING ON THE USE OF DIGITAL COMPUTERS AND DEVELOPMENT OF NEW TYPE SENSOR
MICROSENSOR AND MICROCRONTROLLER ON A SINGLE CHIP SCALED DOWN TO NANO SIZE
SERIAL TRANSMISSIONS
EACH BITS TRANSMITTED ONE BY ANOTHER (HANDSHAKING PROCESS), SPEED OF TRANSMISSION SLOW, THE COST ARE LESS THAN PARALLEL TRANSMISSION.
PARELLEL TRANSMISSION
EACH BITS TRANSMITTED SIMULTANEOUSLY, SPEED OF TRANSMISSION HIGH, THE COST ALSO HIGH
APPLICATIONS
MEDIUM OF DATA TRANSMISSION
FIBRE OPTIC FLOW SENSORE
FIBRE OPTIC TEMPERATURE SENSOR
FIBRE OPTIC PRESSURE TRANSDUCER
FIBRE OPTIC ACCELEROMETER
FIBRE OPTIC TRANSDUCVER
CONSIST OF A THIN , LOW LOSS GLASS WIRE WITH A CENTRE / CORE REGION
TOTAL REFLECTION AT THE BOUNDARY OF THE SORE AND THE CLADDING MATERIAL
DEPENDS ON : THE SIZE OF REGION , SINGLE MODE / MULTIMODE FIBRE
SENSOR WHICH WORK ON THE PRINCIPLE OF ALTERATION OF LIGHT
ADVANTAGES : ENHANCE SAFETY, LOW WEIGHT , SMALL SIZE , IMMUNE TO
ELECTROMAGNETIC
DISADVANTAGES : FRAGILE , ALIGNMENT
PROBLEMS, HIGH COST
