Gas Filled Devices
Gas filled tubes and neon lamps have also been used as voltage references, primarily in tube-based equipment, as the voltage needed to sustain the gas discharge is comparatively constant. For example, the popular RCA 991 "Voltage regulator tube" is an NE-16 neon lamp which fires at 87 Volts and then holds 48–67 Volts across the discharge path.

Famous quotes containing the words gas, filled and/or devices:
“one pale woman all alone,
The daylight kissing her wan hair,
Loitered beneath the gas lamps’ flare,
With lips of flame and heart of stone.”
—Oscar Wilde (1854–1900)
“Reason, progress, unselfishness, a wide historical perspective, expansiveness, generosity, enlightened self-interest. I had heard it all my life, and it filled me with despair.”
—Katherine Tait (b. 1923)
“Soon silence will have passed into legend. Man has turned his back on silence. Day after day he invents machines and devices that increase noise and distract humanity from the essence of life, contemplation, meditation.... Tooting, howling, screeching, booming, crashing, whistling, grinding, and trilling bolster his ego. His anxiety subsides. His inhuman void spreads monstrously like a gray vegetation.”
—Jean Arp (1887–1948)
