0 a piece of equipment that uses a small box whose shape can change in order to measure air pressure and show when the weather is likely to change
The control system used a pneumatic/vacuum system, an electric system and an aneroid barometer/altimeter.
For example, an aneroid barometer uses rotary position as the signal to convey pressure information.
Setting an aneroid barometer is similar to setting an analog clock that is not at the correct time.
He was recognized for his temperature-compensated aneroid barometer.
Temperature compensation of an aneroid barometer is accomplished by including a bi-metal element in the mechanical linkages.
Inside the instrument, there is a sealed aneroid barometer.
The pointer in an aneroid barometer is replaced with a pen.
Older aircraft used a simple aneroid barometer where the needle made less than one revolution around the face from zero to full scale.
