- 2. A recorder records electrical & non-electrical quantities as a function of time. This record may be written or printed, and later on, can be examined and analyzed to obtain a better understanding and control of the processes
- 3. Paper chart – to record information Stylus- writing instrument Interfacing apparatus
- 5. Display and store a pen-and-ink record of the history of some physical event. i) Strip Chart Recorders ii) X-Y Recorders
- 6. Instrument records one or more parameters that change with respect to time. Self balancing or galvanometer One or more parameters with respect to some other- XY recorder
- 7. Signal conditioning to drive chart at desired rate Drives reversible motor Event marker to mark edges of chart
- 10. Circular motion, need special paper
- 12. Mechanical Moving coil Moving iron Electromagnetic Induction meters Electrostatic
- 13. Galvanometer recorder are uses d’Arsonval’s movement But not sensitive Cost and size advantages
- 15. A X-Y recorder is an instrument which gives a graphic record of the relationship between two variables Pen moves in two axes Pen clamped or by creating diff. Pressure to hold pen Expensive Gives time base generator
- 19. X, Y, inputs Multiple channels Time base X, Y, display Single ended inputs Differential inputs
- 20. High frequencies High resolution (fidelity) Magnetic modulation of data Requires complicated recording devices Can be used with strip chart recorders
