n: the temperature-sensing (detecting) element of a temperature-measuring device.

n: a holder for a mercury-in-glass thermometer that incorporates a small metal container into which the bulb of the thermometer is inserted and that serves to hold a small sample of liquid the temperature of which is being measured. The liquid in the cup keeps the bulb sub-merged in liquid until the temperature is recorded.

n: an ordinary light bulb.

n pl: sucker rods that have been broken and separated in a pumping well because of corrosion, improper loading, damaged rods, and so forth. partial immersion thermometer n: a thermometer with a specific length of the bulb and stem immersed the liquid and the scale above the surface for ease of reading.

n: a hygrometer, or psychrometer, attached to a handle and chain cord, which is whirled rapidly through the air. It also has two thermometers. The bulb of one is kept wet so that the cooling that results from evaporation as the thermometers are whirled makes it register a lower temperature than the dry one. The difference between the dry and wet readings is a measure of the relative humidity of the atmosphere. See psychrometer.
