2. TRANSDUCERS
 A device which converts 1 form of energy into
another.
 In a process industry 4 basic and very important
parameters to be measured and controlled are:
1) Flow
2) Temperature
3) Pressure
4) Level

3. FLOW MEASUREMENT

6. TEMPERATURE MEASUREMENT
•Thermocouple
•Thermistor
•RTD
•Bimetallic Thermostat
•Pyrometers

8. COMPARISION OF DIFFERENT
TYPES OF TEMPERATURE
SENSORS

9. PRESSURE MEASUREMENT
 Manometric Method
 Elastic Pressure Transducers
1) Bourdon Tube
2) Bellows
3) Diaphragms
4) Capsule
 Electric Pressure Transducers
1) Capacitive e.g. D.P. Cell
2) Inductive e.g. LVDT

10. PRESSURE GAUGE
 Generally named as Pressure gauges
or Vacuum gauges.
Absolute pressure is zero-referenced
against a perfect vacuum, so it is equal to
gauge pressure plus atmospheric
pressure.
Gauge pressure is zero-referenced
against ambient air pressure, so it is equal
to absolute pressure minus atmospheric
pressure.
Differential pressure is the difference in
pressure between two points
