This is despite the use of a highly sensitive mirror galvanometer, a new invention of the time.

He patented the key elements of his system, the mirror galvanometer and the siphon recorder, in 1858.

Kelvin invented his mirror galvanometer precisely for this task of observing the current change quickly.

The principle behind the siphon recorder is the inverse of the mirror galvanometer.

In 1826, Poggendorff developed the mirror galvanometer, a device for detecting electric currents.

Kelvin had to invent the mirror galvanometer, and later the siphon recorder, to make use of it.

A stereo version, known as a 'doppel lichtzeiger' contained two mirror galvanometer displays in a single housing.

To pursue the analogy with the sprung mirror galvanometer, the more powerful the spring, the faster the mirror will swing back to its original position.

In return, Thomson secured a trial for his mirror galvanometer, about which the board had been unenthusiastic, alongside Whitehouse's equipment.

This was done with the development of the moving-coil oscillograph by William Duddell which in modern times is also referred to as a mirror galvanometer.

A ballistic galvanometer is a type of sensitive galvanometer, commonly a mirror galvanometer.

A mirror galvanometer is a mechanical meter that senses electric current, except that instead of moving a needle, it moves a mirror.

Mirror galvanometer invented by William Thomson, 1st Baron Kelvin.

In about 1936 and 1937, German broadcasters developed a peak programme meter which used a mirror galvanometer known as a 'lichtzeiger' (light pointer) for the display.

The mirror galvanometer was later improved by William Thomson, later to become Lord Kelvin.

The siphon recorder, adapted by Lord Kelvin from the Gauss/Weber mirror galvanometer.

In modern times, the term mirror galvanometer is also used for devices that move laser beams by rotating a mirror through a galvanometer set-up.

There was the Thomson reflecting mirror galvanometer and electrometer, while nearby were the standard cells by which the galvanometers were adjusted and standardized.

Thomson's fears were realised when Whitehouse's apparatus proved insufficiently sensitive and had to be replaced by Thomson's mirror galvanometer.

Thomson designed a complex electric-field generator that minimized current by resonating the cable, and a sensitive light-beam mirror galvanometer for detecting the faint telegraph signals.

In the mirror galvanometer, a small magnet, which is free to rotate round its own axis, is suspended in the centre of a large coil of wire.

The string galvanometer was a type of mirror galvanometer so sensitive that it was used to make the first electrocardiogram of the electrical activity of the human heart.

Because telegraph signals tended to grow faint and distorted over long distances under water, he invented the mirror galvanometer, a receiving device that allowed easy interpretation of weak signals.

The most sensitive form, the Thompson or mirror galvanometer, was improved by William Thomson (Lord Kelvin) from the early design invented in 1826 by Johann Christian Poggendorff.

Use of the Wheatstone bridge relies on achieving a null current with the highest attainable level of precision, and for this purpose, no instrument on earth was better suited than the Kelvin mirror galvanometer.
