DEAD WEIGHT PRESSURE GAUGE TESTER APPARATUS

Product Description

Specification:

DEAD WEIGHT PRESSURE GAUGE TESTER APPARATUS

Deadweight testers are the basic primary standard used worldwide for the accurate calibration of pressure gauges, pressure transducers etc.

The equipment is self-contained and portable so it may be used in lecture theatre demonstrations or as a master calibrator for the laboratory.

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.

A laboratory calibration certificate is supplied for each piston together with a traceable certificate of over all accuracy.

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.

The instrument is supplied complete with necessary weights and a fitted carrying case.

1/8, 1/4, 3/8, 1/2 inches BSP and NPT female adaptors are included together with spare seals and a quantity of oil.
