The present invention relates to system for calibrating plurality of pressure transducers, said system comprising plurality of pressure transducers (to.n) mounted on a mounting means () which receives pressure input from a pressure source () via a hollow pipe () 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 () as to vary the temperature of the pressure transducers, said pressure source is also connected to a standard pressure transducer () whose temperature is maintained at the same level as that of pressure transducers (to.n).

System for calibration of pressure transducers

The present invention relates to a segmented cylindrical tide staff system &lsqb; &rsqb; for erection at remote areas for dynamic calibration of electronic tide meters and computer models of tides, said tide staff system consisting of plurality of cylindrical tubes &lsqb; &rsqb;, said cylindrical tube being coupled to a flange &lsqb; &rsqb; at its end through a circular orthogonal hole &lsqb; &rsqb; drilled on a flat surface of the flange, said flange being provided with plurality of equally spaced slots &lsqb; &rsqb; drilled on the flat surface of the flange, an outwardly protruding tide indicating arm &lsqb; &rsqb; being mounted on the flange wherein said tide indicating arm consists of two mutually orthogonal planes &lsqb; &rsqb; and &lsqb; &rsqb;, wherein plane &lsqb; &rsqb; is perpendicular to the axis of the tide staff and plane &lsqb; &rsqb; is parallel to the axis of the tide staff, said perpendicular plane &lsqb; &rsqb; being provided with a mounting terminal &lsqb; &rsqb; and a circular hole &lsqb; &rsqb; and said parallel plane being partitioned into two compartments &lsqb; &rsqb; and &lsqb; &rsqb; by a separating line &lsqb; &rsqb; thereby permitting indication of tide reading in more than one language, including a vernacular language and two or more cylindrical tubes being coupled to each other through slots &lsqb; &rsqb; using coupling means.
