What's the difference between galvanometer and galvanometry?

Galvanometer

Definition:

(n.) An instrument or apparatus for measuring the intensity of an electric current, usually by the deflection of a magnetic needle.

Example Sentences:

(1) Three types of Berger's early investigations are described: (1) String-galvanometer recordings obtained between 1924 and 1926, mainly from trephined patients with cerebral diseases, which usually showed brain waves slowed to 6--8 per second; (2) Direct recordings from the cortex and white matter proving the cortical origin of the EEG in 1930; (3) Typical unpublished EEG recordings of epileptics and of petit-mal attacks obtained in 1930 and 1931.
(2) "Effective streaming currents" were determined by running the output through a low impedence galvanometer while simultaneously measuring the resistance of the circuit V(8) were, therefore, calculated from two measurements and compared.
(3) Films are presented for tracking on a translucent screen after reflection from a galvanometer driven mirror.
(4) Despite the universal use of the electrocardiogram for cardiac evaluation, surprisingly few physicians are aware of the individual, Willem Einthoven, who in 1901 reported and in 1924 received the Nobel Prize for the development of the string galvanometer electrocardiograph.
(5) He constructed the string galvanometer and thus he created an essential technical basis for the development of clinically applicable electrocardiographs.
(6) The results of heat measurements, using a sensitive thermopile-galvanometer system, are compatible with the hypotheses that this effect on relaxation could result from either an interference with calcium reuptake by the sarcoplasmic reticulum or an increased affinity of the troponintropomyosin complex for available calcium.
(7) When Einthoven developed the elegant, reliable and sensitive string galvanometer, he could record the electric forces of the heart from the hands and feet of the subject without even undressing him.
(8) The hook was soldered to the pivot of a galvanometer that was controlled by a waveform generator.
(9) Volta's doctrine prevailed over Galvani's school after Volta's breakthrough with his pile, or battery, until Galvani's ideas were rehabilitated by Nobili, who in 1828 measured the 'frog current' with his galvanometer.
(10) The scanning apparatus of our system, paired galvanometer mirrors, can perform narrow band scanning of an area of interest at a high temporal resolution of less than 70 msec per image.
(11) This report deals with a simplified and improved method for measuring the force-velocity relationship of the cat papillary muscle by means of a coil-type galvanometer and a horizontally oriented lever system.
(12) When Einthoven's great galvanometer became available, only the three standard limb leads were used.
(13) We have developed a new confocal laser scanning microscope equipped with two galvanometer mirrors which swing the laser beam.
(14) Electrocardiography only became clinically relevant in 1901 when Willem Einthoven devised his string galvanometer for this purpose.
(15) The present invention is based on the use of two ballistic galvanometers in connection with an ECG-Bcg set, making it unnecessary to change poles mechanically each time in order to take in surface values above and below the zero line.
(16) Two designs use servo-controlled DC motors configured as velocity servos and a third design uses a galvanometer motor configured as a position servo.
(17) The interest towards intraventricular conduction defects started some 10 yr after the introduction of the string galvanometer by Einthoven.
(18) The galvanometer-mirror assembly is mounted on an arm which can be rotated through 90 degrees.
(19) The indicated values of the ballistic galvanometer can, on the one hand, be read directLy or, on the other hand, be documented mechanically by means of a film camera or by a photographic camera with or without different adjustable time delays or by electronic coupling after applying the measurement(s).
(20) Raster scan of the beam is provided by two orthogonal mirror galvanometers.
