An arc-shaped, spiral, or helical metal tube that is approximately elliptical in cross-section and has one end attached to a pressure indicating, controlling, or recording device, while the other end is fixed. Pressure changes inside the tube affect its shape and actuate the device to which it is attached.
a pressure sensing element constructed from a flattened tube, seal at one end, twisted or curved. Applied pressure untwists the tube
a coiled flattened tube that wants to straighten out when pressure is applied to it
a round, hollow metal tube
A pressure sensing element consisting of a twisted tube of noncircular cross section closed at one end. When a process stream is routed to the open end of the tube, any increase in the pressure will cause the tube to unwind.
Closed, curved, flexible tube of elliptic cross section which is deformed, according to type, by variations of atmospheric pressure or temperature and so provides a measurement of the particular parameter.
A curved metal tube (sealed at one end) that flexes to a known degree when pressurized internally.
A pressure sensing element consisting of a twisted or curved tube of noncircular cross section which tends to be straightened by the application of internal pressure. Also known as "Bourdon element" when used in a "Bourdon pressure gauge."
A hollow, metallic tube, bent semicircular, which forms the actuating medium of a pressure gauge.
A thin, curved, hollow, pressure-sensitive tube that is found in some pressure gauges and operates the needle of the gauge. Part of a pressure gauge that has a curved, flat tube that changes its curvature as pressure changes. This movement is then transferred mechanically to a pointer on the dial.
C-shaped tube manufactured of thin metal and closed on one end. When pressure is increased inside, it tends to straighten. it is used in a gage to indicate pressure.
