1. Telemetry Principles
Zankhana Mehta

2. block diagram of telemetry system

3. Types of Telemetry System
According to Energy Medium
Pneumatic,
Hydraulic
According to Electrical
Current, Voltage
Pulse
According to Signal Type
Analog,
Digital

4. Pneumatic Telemetry

5. Advantages High effectiveness High durability and reliability
Simple design
High adaptability to harsh environment
Safety
Easy selection of speed and pressure
Environmental friendly

6. Disadvantages Relatively low accuracy Low loading
Processing required before use
Uneven moving speed
Noise

7. Hydraulic Telemetry

8. Advantages It gives more power than pneumatic systems.
Its reliable to operate.

9. Disadvantages Slower motion than pneumatic. Complex construction.
Leakage of oil problem
More maintenance than pneumatics

10. Current telemetry

11. Current telemetry

12. Voltage Telemetry

13. Pulse Telemetry

14. Pulse Modulation

15. According to Signal Type
Analog Telemetry System: If the information in the form of current, voltage, Possion, frequency than the system is called analog system

16. According to Signal Type..
Digital Telemetry System: If the information is transmited in the form of pulses than the system is called Digital telemetry system

17. Compare the merits and demerits of Hydraulic, Pneumatic and Electric Telemetry

18. Compare the merits and demerits of Hydraulic, Pneumatic and Electric Telemetry…..

19. Standard output ranges of all types of telemetry systems
Current : 4-20 mA
Voltage : 0-24 V
Pressure : 3-15 psi
