7. THE USE OF SENSORS IN PROCESS CONTROL MEASURES PROCESS VARIABLES OR PHYSICAL QUANTITIES

8. The Definition of Sensor Sensors are devices that produce output signals for the purpose of sensing physical phenomena. A sensor is a device that receives and responds to physical signals. These signals are produced by some type of energy such as heat, light, motion or chemical reactions The sensor detects one or more input signals, these input signals are converted into analog or digital representation. In general, sensors convert a recognized signal into an electrical signal (current or voltage).

9. CLASSIFICATION OF SENSORS ( BASED ON USE IN THE CONTROL PROCESS ) Requires an external source power to operate

10. ACTIVE AND PASSIVE SENSOR A c ti ve Sensor : A type of sensor that produces an output signal without the help of an external excitation voltage. Usually referred to as a sensor that produces its own signal ( Self generating sensor ) EXAMPLE : Photovoltaic cells, Thermocouples, Piezoelectric device

11. Pa s si ve Sensor : A type of sensor that produces an output signal with the help of an external excitation voltage. Requires extra stimulation or extra tension. EXAMPLE : RTD, Strain Gauge ACTIVE AND PASSIVE SENSOR

12. CLASSIFICATION OF SENSORS (BASED ON SIGNAL PROCESSING ) DIGITAL SENSOR (ON/OFF SIGNAL) ANALOG SENSOR (RANGE VALUE)

13. DIGITAL SENSOR Digital sensors produce discrete output signals. Represented in 'bits' for serial transmission and 'bytes' for parallel transmission. Digital output in the form of logic 1 and logic 0 (ON or OFF). Digital sensors consist of sensors, cables and transmitters. Cables are used for long distance transmission. LIMIT SWITCH OFF CONDITION LOGIC 0 ON CONDITION LOGIC 1

14. EXAMPLES OF DIGITAL SENSOR APPLICATIONS POSITION (WATER LEVEL) HIGH /FULL LOW /EMPTY

15. EXAMPLES OF DIGITAL SENSOR APPLICATIONS CONDITION (POWER ON AND OFF) POWER OFF POWER ON

16. VARIOUS EXAMPLES OF DIGITAL SENSORS

17. ANALOG SENSOR Sensors that produce continuous signals with time response with analog output are called analog sensors. In general, an analog voltage in the range 0-5V or current is produced as output. Analog sensors change physical variables into signals that can be understood by a control system ( eg PLC) such as voltage or current. These physical variables such as temperature, pressure, speed, displacement, etc.

18. These physical variables must be converted into electrical quantities in the form of industry standard current and voltage (4-20mA, 12-24 V) before being processed by the controller.

21. TRANSDUCER A transducer is a device that converts from one form of energy to another form of energy.

22. Recommended transducer requirements for use: Small size and Lightweight High sensitivity Can maintain environmental conditions Cheap

23. TYPES OF TRANSDUCERS TRANSDUSER INPUT and TRANSDUSER OUTPUT

24. TRANSDUSER INPUT Transducers that can convert physical energy into electrical signals or resistance (which are then also converted to voltage or electrical signals). This physical energy can be in the form of light, pressure, temperature or sound waves. For example, a microphone can convert sound waves into electrical signals that can be transmitted via electrical cables. Input Transducers are often also called Sensors.

25. EXAMPLE OF TRANSDUCER OUTPUT LDR (Light Dependent Resistor) converting Light into Resistance Thermistor (NTC/PTC) converting Temeperature into Resistance Variable Resistor ( Potensiometer ) converting position into Resistance Mikropon (Microphone) convert sound waves intoelectrical signal

26. TRANSDUCER OUTPUT Output Transducer is a transducer that can convert electrical signals into a form of physical energy (Physical Energy). For example, loudspeaker Loudspeakers convert electrical signals into sounds that humans can hear. Output transducers are often also called actuators.

27. EXAMPLE OF TRANDUSER OUTPUT LED (Light Emitting Diode) convert electricity into Light Energy Lampu convert electricity into Light Energy – Motor convert electricity into motion – Heater convert electricity into heat – Loudspeaker convert electricity into sound
