diff between dead wt calibrator n pressue comparator?..

Answer / vidal r. ramoso

ok, deadweight calibrator is an intrument with hydraulic
pressure having lifting piston with plat round platform use
to carry plate with round plat massess with standard value
use as a standard reference to clibrate pressure gauge or
any other pressurize instrsument. while the pressure
comparator is having standard calibrated pressure/vacuum
gauge use as a reference to check pressure/vacuum gauge.
pneumatic transmitter, etc.not to calibrate

Answer / maya ramesh

Answers 1 & 2 are Almost correct. But the Statement "Comparators are not used for calibrating the gauge" is not corect. If the standard test gauge used for comparing is a master test gague or having the traceiablility...Pr. Comparators are also can be used for the Calibration. In fact any home made pressure generating source also can be used for the calibration if we use the Master Test Gauge (certified) as reference.

For you information Pressure generating sources dont need any certifications or Traceiabilty.
