263 INSTRUMENTATIONThe Amerada mechani caI gauges were used for both tempera ture and pressure measurements used in this researchproj ect.There are two main types of mechanical gauges, namely theAmerada temperature gauge, which has a bourdon tube wherethe boiling pressure of a special fluid Is recorded, andthe Kuster gauge which has a bimetal sensor where thetemperature torsion of the bimetal indicates the tempera -ture. When using the mechanical gauges data Is nottransmitted to the surface, but is recorded inside theprobe on a clock driven recorder. As many as 20 - 30measuringwell.pOints can be recorded during one run 1n theThe Amerada gauges consist of three basic parts, therecording section, a clock and either a pressure sensor ora temperature sensor (Figures 8 and 9).3.1 Pressure elementThe active element in the pressure element i s a helicalbourdon tube, fixed at one end and free to rotate at theo t her. The interior of the tube is subjected or exposed tothe pressure in the well. The resulting rotation of thefree end of the bourdon tube is transmitted directly to arecording stylus without the use of gears or levers. Thestylus records on a metal chart made of thin metal coatedon one side with a special paint. The paint rendersfriction extremely low and the scribed lines are so easilyvisible that the chart scanner user can measure chartdeflections to obtain the accuracy the gauge is capable ofproducing. The chart is carried on a removable cylindricalchart holder, the position of which is controlled by aclock.
