Deadweight Testers
Deadweight testers generate pressure by loading calibrated masses onto a piston of known area, producing a pressure derived from first principles rather than from an electronic sensor.
Fluke, Ametek, DH-Budenberg and Ashcroft cover this range. Because the output depends on mass, local gravity and piston area, a deadweight tester holds its accuracy over long periods and is normally the primary reference at the top of a pressure calibration hierarchy. Specify whether the work is pneumatic or hydraulic, since the piston and fluid systems differ, and state the local gravity value at the site so the mass set can be corrected. Confirm the accuracy class you need against the instruments you will calibrate.
The Fluke Pressurements P3014-KGCM2-P deadweight tester provides better than 0.015% of reading accuracy across vacuum to 2000 psi (140 bar), with gas operation, optional hand pumps, and multi-unit pressure support for calibration work.
The Fluke Pressurements P3223-KGCM2 Deadweight Tester delivers pressure calibration to 20,000 psi (1,400 bar) with accuracy better than 0.015% of reading and fine control from its pump and screw press. Request a quotation from Indo Multimeter.
Fluke Pressurements P3023-MBAR-P pneumatic deadweight tester with better-than-0.015% accuracy, vacuum to 2,000 psi (140 bar) range, hand-pump options, and precision leveling.
