Precision Pressure Gauge Calibrator
Product Code : EL-FMLE-10678
The equipment is self-contained and portable, so it may be used in lecture theatre demonstrations or as a master calibrator for the laboratory.
Dead weight testers are the basic primary standard used worldwide for the accurate calibration of pressure gauges, pressure transducers etc.
The instrument combines a low and high-pressure range provided by two pistons of different effective area.
Calibration is accurate to within ±0.025% of reading.
The pressure in the system is produced by means of a capstan-operated hydraulic ram, balanced by dead weight acting upon a piston of known area.
Oil is 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.
A flotation indicator mounted on the top plate removes the guesswork when floating the piston.
A laboratory calibration certificate is supplied for each piston together with a traceable certificate of overall accuracy.
The instrument is supplied complete with necessary weights and a fitted carrying case. â…›”, ¼”, â…œ”, ½” BSP and NPT female adaptors are included together with spare seals and a quantity of oil.
