Patent ID: 6848292

Claim:
A system for calibrating a plurality of pressure transducers, said system comprising a plurality of pressure transducers ( 13 . 1 to 13 .n) mounted on a mounting means ( 12 ) including a cylindrical body having an input channel ( 30 ) connected to a hollow pipe ( 14 ) via link ( 31 ) and an adapter ( 32 ) to receive the pressure, said cylindrical body is cast with a plurality of channels ( 26 . 1 to 26 .n) alone its radius and terminating at its periphery for distributing the pressure equally to all the pressure transducers, said channels are provided with slots ( 29 . 1 to 29 .n) at equidistant points from the center of the cylinder to accommodate the inlets of the pressure transducers and said channels are closed at the periphery using plugs ( 27 . 1 to 27 .n) and leak-protected washers ( 28 . 1 to 28 .n), said pressure transducers ( 13 . 1 to 13 .n) receiving pressure input from a pressure source ( 11 ) via a hollow pipe ( 14 ) and distributes the pressure evenly to all the pressure transducers, said plurality of pressure transducers are mounted on the mounting means and placed inside a vessel ( 15 ) so as to vary the temperature of the, pressure transducers, said pressure source is also connected to a standard pressure transducer ( 17 ) whose temperature is maintained at the same level as that of pressure transducers( 13 . 1 to 13 .n).
