Contact uS for more updates
*These questions are expected for the exams This may or may not be asked for exams All the best.... from admin Santhosh
Thanks for your love and support guys keep supporting and share let the Engineers know about Us and leave a comment below for better improvements If there is any doubt feel free to ask me I will clear if I can or-else I will say some solutions ..get me through WhatsApp for instant updates ~$tuff$£ctorSYllabuSUNIT I FUNDAMENTALS OF MEASUREMENTS
Measurement System – Instrumentation - Classification and Characteristics of Transducers - Static and
Dynamic - Errors in Measurements and their statistical analysis- methods of error analysis,-uncertainty
analysis-expression of uncertainty: accuracy and precision index, propagation of errors– Calibration -
Primary and secondary standards.
UNIT II DISPLACEMENT, PRESSURE, TEMPERATURE SENSORS
Strain Gauge: Gauge factor, sensing elements, configuration, and unbounded strain gage. Capacitive
transducer - various arrangements, Inductive transducer, LVDT, Passive types: RTD materials &
range, relative resistance vs. temperature characteristics, thermistor characteristics, Active type:
Thermocouple - characteristics.
UNIT III PHOTOELECTRIC AND PIEZO ELECTRIC SENSORS
