The document discusses different types of intermediate modifying systems used in mechanical and electrical measurement systems. In mechanical systems, an input signal is converted to a displacement then to an analogous form by primary and secondary transducers. Some systems use mechanical intermediate stages like linkages, gearing, or cams. Electrical systems can use ballast circuits, Wheatstone bridge circuits, and terminating devices as intermediate modifiers. Electronic systems and cathode ray oscilloscopes are also discussed as intermediate modifying techniques. Different types of oscillographs like stylus type, mirror type light beam, and XY recorders are outlined.
2. MECHANICAL SYSTEMS
In mechanical measurement systems an input signal
is converted into a displacement by the primary
detector-transducers. Generally secondary
transduces are used to convert this into an
analogous form thus making the processing easier.
In some cases, input is fed to mechanical
intermediate stages, such that linkages, gearing or
cams. This magnitude is very high when the systems
receive and handle dynamic input signals.
