An instrument used for measuring atmospheric pressure
Barometer
A pressure sensor that converts pressure into linear displacement.
Bellows
A flow equation based on the conservation of energy which includes velocity, pressure, and elevation terms.
Bernoulli equation
The ratio of the diameter of a restriction to the diameter of the pipe containing the restriction.
Beta ratio
A thermometer with a sensing element made of two dissimilar metals with different thermal coefficients of expansion.
Bimetallic
Two values, or a numbering system using the base 2.
Binary
A binary digit.
Bit
A pressure sensor that converts pressure to movement. The device is a coiled metallic tube that straightens when pressure is applied.
Bourdon tube
A network of passive components arranged so that small changes in one of the components can be easily measured.
Bridge
A measure of heat energy, i.e., the amount of heat required to raise 1 lb of water 1°F at 68°F and atmospheric pressure.
British thermal unit
A circuit for matching the output impedance of one circuit to the input impedance of another.
Buffer amplifier
The upward force on an object floating or immersed in a fluid caused by the difference in pressure above and below the object.
Buoyancy
Eight bits of binary information.
Byte
A measure of heat energy, i.e., the amount of heat required to raise the temperature of 1 g of water 1°C.
Calorie
A measure of a device’s ability to store electrical charge.
Capacitance
