[f. Gr. πλείω-ν more (see pleio-) + -tron.]
A high-vacuum thermionic valve with one or more grids.
| 1915 I. Langmuir in Electrician 21 May 242/2 The term ‘Pliotron’ has been adopted to designate a Kenotron, in which a third electrode has been added for the purpose of controlling the current flowing between the anode and the cathode. 1918 Wireless World July 230 The characteristics of the pliotron depend upon the length of filament used. 1945 Cooke & Markus Electronics Dict. 278/2 Pliotron, a high vacuum thermionic tube in which one or more electrodes (grids) are employed... All amplifier tubes in radio sets are pliotrons, but the term has never gained extensive use. 1971 G. M. & R. D. Chute Electronics in Industry (ed. 4) x. 167 A third element, called the grid, is placed between the anode and cathode to form a high-vacuum type of triode (also called the pliotron). |
