The electrical measurement of physical properties
LO Hunter · New Zealand Engineering · 1971
An introduction to the electrical measurement of physical properties with suggestions for transducers and instruments. Advances in solid-state technology have made practicable in portable equipment methods which were formerly limited to mains-operated instruments. The same technology which produced the digital voltmeter and data processor has made available the data logger, a device capable of scanning many transducers at high speed and printing out information as often as required or storing it on magnetic tape if the acquisition rate is too high for a printer.
