QUESTION ELECTRONIC DEVICE TO TRANSFORM ELECTRONIC QUANTITY

QUESTION 1EXPLAIN ELECTROMAGNETIC ACTUATOR ?SOLUTION:ACTUATOR—IT IS AN ELECTRONIC DEVICE WHICH CONVERT ELECTRONIC QUANTITY INTO MECHANICAL QUANTITY.ELECTOMAGNETIC ACTUATOR—IT IS SUCH TYPE OF ELECTRONIC DEVICE TO TRANSFORM ELECTRONIC QUANTITY INTO MECHANICAL QUANTITY BY USING MAGNETIC FIELD AND CURRENT.

WORKING=IT CONSIST OF A CYLINDRICAL COIL WOUND BY A WIRE WHICH CONTAIN ELECTRIC CURRENT ON THE FRAME.IT ALSO CONTAIN A SHELL PR A MOVABLE COIL WHICH IS KEPT IN THE AXIX IN IT TO PRODUCE MAGNETIC CIRCUIT . BY APPLYING CURRENT IN THE COIL AND DUE TO MAGNETIC FIELD IT STARTS ROTATING .

.THEN THIS WORKING HELP HIM TO TRANSFORM THE ELECTRICAL QUANTITY INTO MECHANICAL QUANTITY.QUESTION 2:WHAT IS ACTUATOR . EXPLAIN MOVING COIL ACTUATOR AND MOVING MAGNETIC ACTUATOR?ANSWER:ACTUATOR:- IT IS A DEVICE WHICH CONVERT THE ELECTICAL QUANTITY INTO MECHANICAL QUANTITY.

MOVING COIL ACTUATOR:A MOVING COIL ACTUATOR IS COMMONLY KNOWN AS VOICE COIL ACTUATOR WHICH IS USED TO MAVE LARGER MASS FROM ONE PLACE TO ANOTHER.IT CONSIST A PERMANENT MAGNET AND SOME STEEL AND A COIL WHICH IS ASSEMBLED IN SUCH A WAY THAT WHEN THE CURRENT IS FLOWING TO THE COIL THEN IT INRACVT WITH MAGNETIC FIELD AND GENERATES A FORCE WHICH IS PERPENDICULAR TO THE DIRECTION OF CURRENT.MOVING MAGNETIC ACTUATOR:A MOVING MAGNETIC ACTUATOR IS SUCHH TYPE OF ACTUATOR WHICH IS USED TO CONVERTING THER ELECTRICAL QUANTITY INTO MECHANICAL QUANTITY.

IT CONSIST A PERMANENT MAGNETIC FIELD AND A COIL WHICH IS ASSEMBLED IN SUCH A WAY THAT WHEN CURRENT FLOW THROUGH THE COIL THEN A FORCE IS GENERATED WHICH IS EQUAL AND OPPOSITE BETWEEN THE COIL AND MAGNET.QUESTION 3:WHAT IS THE FUNCTION OF TEMPERATURE SENSOR? HOW THE TEMERATURE SENSOR WORK.ANSWER:-TEMPERATURE SENSOR:IT IS A SUCH TYPE OF SENSOR WHICH IS USED TO MEASURE THE TEMPERATURE EVEN HOT OR COLD WHICH IS GENERATE BY A BODY OR A OBJECT.WORKING:TEMPERATURE SENSOR WORKS WHEN TEMPERATURE SENSOR IS APPLIED VOLTAGE ACROSS THE DIODE THEN IF THE VOLTAGE IS INCREASES THEN TEMPERATURE ALSO INCREASES. DUE TO THIS IT PRODUCES A VOLTAGE DROP BETWEEN THE TERMINALS OF BASE AND EMITTER .

THEN THE SENSOR RECORDED THIS CHANGES . IF THE DIFFERNECE OF VOLTAGE IS AMPLIED THEN IT SHOWS THE CHANGE IN TEMPERATURE.QUESTION 4:EXPLAIN DIFFERENT MICRO ACTUATOR METHODS?ANSWER:MICRO ACTUATOR:A MICERO ACTUATOR IS BASED ON SERVO MOTAR WHICH IS USED TO CONVERT AMOUNT OF ENERGY INTO MECHANICAL ENERGY .THE DIFFERENT TYPES OF MICRO ACTUATORS ARE AS FOLLOWS:-1. ELECTROSTATIC ACTUATOR:ELECTROSTATIC ACTUATOR IS A SUCH TYPE OF TRANSDUCER WHICH IS USED TO CONVERT THE ELECTRICAL QUANTITY INTO MECHANICAL FORCE AND PRESSURE.

AMONG SEVERAL ELECTROSTATIC ACTUATOR , CAPACITANCE IS COMMONLY KNOWN AS ACTUATOR.CAPACITANCE IS USED TO CONVERT THE APPLIED VOLTAGE INTO EQUIVALENT FORCE AND PRESSURE.2. ELECTROMAGNETIC ACTUATOR:IT IS SUCH TYPE OF ELECTRONIC DEVICE TO TRANSFORM ELECTRONIC QUANTITY INTO MECHANICAL QUANTITY BY USING MAGNETIC FIELD AND CURRENT3.

THERMAL ACTUATOR:THE THERMAL ACTAUTOR IS SUCH TYPE OF TRANSUDER WHICH IS USED AS CHANGE THE HOT AND COLD GENEARTED BY A BODY PRODUCES A MECHANICAL CHANGES.QUESTION 5:EXPLAIN THE CALIBRATION ERROR, HYSTERSIS ERROR AND NON LINEARITY ERROR WITH NEAT DIAGRAM?ANSWER:CALIBRATION ERROR:WHEN THE OUTPUT READING IS OF ANY INSTRUMENT IS GIVING WRONG THEN A CALIBRATION ARE USED TO CALIBRATE IT AND THIS IS CALIBRATION ERRORS.HYSTERESIS ERROR:IT IS THE DIFFERENCE BETWEEN OF INCREASING RANGE POINT WITH DECREASING RANGE POINT OF A PRESSURE SENSOR.NON LINEARITY ERROR:IN THIS ERROR , THERE IS DEVIATION IS GENERATED IN A STRAIGHTLINEAR GRAPH WHICH IS ALSO CALLED LINEALITY ERROR.
