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:
“Papa died in the gas chamber,
slipping blue as an undressed minnow,
gulping in the shower to wash the Jew off him.”
—Anne Sexton (19281974)
“they filled his belly
with large stones and sewed him up.
He was as heavy as a cemetery
and when he woke up and tried to run off
he fell over dead. Killed by his own weight.
Many a deception ends on such a note.”
—Anne Sexton (19281974)
“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 (18871948)
