	Mechanical Pressure Gauges Description (Site not responding. Last check: 2007-10-21)
		Mechanical pressure gauges are produced with bourdon tube, diaphragm, and bellow and spring elements and are accordingly different.
		Bourdon tubes are circular-shaped tubes with an oval cross-section.
		Compared with bourdon tubes, these diaphragm elements have a relatively high activating force and because of the circular clamping of the element they are insensitive to vibration.

		A chalumeau with beak mouthpiece and characteristic short cylindrical tube pierced with six holes figures among the musical instruments used fr the triumphal procession of the emperor Maximilian I., commemorated by a fine series of plates,6 engraved on wood by Hans Burgkmair, the friend and colleague of A. Durer.
		It was for the Stadler brothers that Mozart wrote his quintet for strings, with a fine obbligato for the clarinet in A (1789), and the clarinet concerto with orchestra in 1791.
		In 1842 H. Klos conceived the idea of adapting to the clarinet the ingenious mechanism of movable rings, invented by Boehm for the flute, and he entrusted the execution of this innovation to Buffet-Crampon; this is the type of clarinet generally adopted in French orchestras.

		By joining the lateral tube with the pneumatic machine or with the container where the rarefaction is produced, the apparatus works as a vacuum gage.
		It is a tube for manometer, but with a very thin wall, so that it can be used as a manometric tube or as a vacuum gage.
		The two branches of the glass tube are joined in the bottom with a connection of iron provided with a lateral key for the unloading.

	BAGPIPE - LoveToKnow Article on BAGPIPE (Site not responding. Last check: 2007-10-21)
		The bag-pipe forms the link between the syrinx (qv.) and the primitive organ, by furnishing the principle of the reservoir for the windsupply, combined with a simple method of regulating the soundproducing pressure by means of the arm of the performer.
		The sound is produced by the stream of air forced from the bag into the drone-pipe by the pressure of the performers arm, causing the tongue of reed to vibrate over the aperture, thus setting the whole column of air in vibration.
		The chaunter consists of a conical wooden tube terminating in a hell and measuring from 14 to 16 in.

		However, in high-pressure gauges spiral tubes are used; the spiral rotates as pressure increases and the tip screws forwards.
		When the pressure inside the tube increases, the tube uncurls slightly causing a small movement at its closed end.
		Bourdon gauges are often fitted to cylinders of compressed gas used in industry and hospitals.

		The bourdon tube pressure instrument is one of the oldest pressure sensing instruments in use today.
		The bourdon tube (refer to Figure A-1) consists of a thin-walled tube that is flattened diametrically on opposite sides to produce a cross-sectional area elliptical in shape, having two long flat sides and two short round sides.
		Since the tube is permanently fastened at one end, the tip of the tube traces a curve that is the result of the change in angular position with respect to the center.

		It resembles the bourdon stop on the organ, and in the lowest register, more especially, the tone is somewhat hollow and wanting in.
		The low pitch of the bass clarinet (8 ft. tone) contrasted with the moderate length of the instrumentwhose bore measures only some 42 to 43 inches from mouthpiece to bell, whereas that of the bassoon, an instrument of the same pitch, is twice that lengthis a puzzle to many.
		An explanation of the fact is to be found in the peculiar acoustic properties of the cylindrical tube played by means of a reed mouthpiece characterizing the clarinet family, which acts as a closed pipe speaking an octave lower than a~n open pipe of the same length, and overblowing a twelfth instead, of an octave.

		A capillary tube is connected with and extends from the Bourdon tube to the exterior of the housing and about which it is formed and supported.
		When a capillary tube for such control means is damaged and the control means fails to function properly, malfunctioning of the control means is most often attributed to the failure of some part or portion of a controller within the controller housing and/or to an inferior quality of the control means as a whole.
		The Bourdon tube 85, when subjected to low internal fluid pressures, is or remains tightly circularly-curved and such that the set screw 88, engaging the read 75, holds the upper end of the reed inwardly to maintain the switch in its normal open or unactuated position.

		As the bourdon tube may be damaged by high temperatures, it is common practice on steam systems to install the gauge at the end of a syphon tube.
		The syphon tube is filled with water which transmits the pressure of the working fluid to the bourdon tube, enabling the gauge to be located some distance from the actual point where the pressure is being measured.
		The bourdon type pressure gauge is not suitable for use on corrosive liquids or fluids containing suspended solids alone, as these solids may damage the internal elements of the gauge.

	eFunda: Introduction to Bourdon Tubes
		The Bourdon Tube is a nonliquid pressure measurement device.
		A typical Bourdon tube contains a curved tube that is open to external pressure input on one end and is coupled mechanically to an indicating needle on the other end, as shown schematically below.
		The external pressure is guided into the tube and causes it to flex, resulting in a change in curvature of the tube.

		This oscillator is attached to a Bourdon tube that is open on one end to the ocean environment.
		As a tsunami wave crest passes over the instrument, the increased pressure causes the Bourdon tube to uncurl, stretching the quartz crystal and increasing the vibrational frequency.
		Conversely, the passage of a tsunami trough reduces the pressure, allowing the Bourdon tube to curl more tightly, thereby compressing the quartz crystal and lowering the vibrational frequency.

	Technical Information About Ashcroft Precision Process Instrumentation
		A white hot billet is extruded or pierced into a 2" to 3" diameter “tube shell” which must be reduced to the size needed in a long and cumbersome series of drawing and annealing operations.
		This tubing is made from annealed strip, similar to welded and drawn, but is not subjected to any further operations – the welded tubing is formed directly into the finished Bourdon tube.
		The weld is oriented on the lowest stressed area of the Bourdon tube cross-section on the flat, instead of on the edges.

	Selecting a Pressure Gauge
		Winters utilizes bourdon tubes that are “C” or spiral shaped pressure tubes that are utilized throughout all industries.
		As pressure is applied through the socket, the bourdon tube straightens itself causing the precision movement to shift upward or downward for vacuum measurements.
		As the bourdon tube is in direct contact with the medium being measured, the medium characteristics must be considered.

	Heise Gauges, Volume Controllers, Indicators, Calibrators, and Pressure Transducers
		Invented in 1832 by French engineer Eugene Bourdon, the Bourdon tube is simply a bent or curved tube with a sealed end, which begins to straighten when pressure is applied into the open end.
		Bourdon tubes can be made in a variety of shapes ("C" shaped, helical, spiral) and can be manufactured in a variety of metals as well as quartz.
		When ordering a replacement Bourdon tube, please be sure to specify the model type, pressure range, the tube material (if no tube material is specified, we will provide the standard material for that range) and whether the tube is for a back or bottom inlet gauge.

		The interior of the Bourdon tube is connected by a hollow coupling to a source of pressure to be measured.
		The end of the Bourdon tube undergoes displacement, which is translated by a pointer mechanism, to become a corresponding angular displacement of a pointer over a dial.
		The angular position of the pointer is proportional to the measured pressure that is indicated by a gradient scale on the dial.
