Measurement and Instrumentation

Electrical instruments depend on the mechanical movement of an indicating device having some inertia and thus have a limited time response. The detector, intermediate transfer device and induction are used for the detection of electromagnetic produced signals such as radio, video and microwave space applications and computers. The cathode ray oscilloscope is an electronic test instrument. In the early days, it was called an Oscillograph. The Digital Storage oscilloscope has been developed to analyse the signal digitally and stores the data in the electronic digital memory. This chapter also includes information on the static and dynamic characteristics of measurements, measurement of errors, and transducers. The principle of the Hall‐effect transducer is that the current carryingstrip of the conductor is placed in a transverse magnetic field, then theEMF develops on the edge of the conductor.
