Dead Weight Pressure Gauge Calibrator
Product Code : EL-FMLE-10654
QUICK ANSWER: The Dead Weight Pressure Gauge Calibrator is a portable, self-contained bench-top instrument used as a primary standard to calibrate pressure gauges, pressure transducers, manometers and Bourdon gauges by the deadweight method, accurate to within ±0.025% of reading over a 1–1,200 bar range. A capstan-operated hydraulic ram, using oil as the hydraulic fluid, balances deadweights acting on a piston of known area to produce pressure, with two pistons of different effective area covering a low- and high-pressure range, a spirit level and adjustable feet for leveling the instrument, and a flotation indicator on the top plate to remove the guesswork when floating the piston; a laboratory calibration certificate is supplied for each piston together with a traceable certificate of overall accuracy. The unit is supplied complete with a carrying case, a set of weights with a minimum standard increment of 0.05 bar, a Bourdon gauge with inlet and outlet valves, and educational software available as an option.
The advanced equipment is self-contained and portable, so it may be used in lecture theatre demonstrations or as a master calibrator for the laboratory. Deadweight testers are the basic primary standard used worldwide for the accurate calibration of pressure gauges, pressure transducers etc., and this instrument combines a low- and high-pressure range provided by two pistons of different effective area, with calibration accurate to within ±0.025% of reading.
The pressure in the system is produced by means of a capstan-operated hydraulic ram, balanced by deadweight acting upon a piston of known area, with oil used as the hydraulic fluid; the pressure developed is applied to the gauge that is to be calibrated. A spirit level and adjustable feet are provided to enable the operator to level the instrument, and a flotation indicator mounted on the top plate removes the guesswork when floating the piston.
