Primary standard for the calibration of differential pressure measuring instruments under static pressure
Reference instrument for factory and calibration laboratories for the testing, adjustment and calibration of pressure measuring instruments
Complete, stand-alone system, also suitable for on-site use
Special Features
Measuring ranges (= static pressure + differential pressure) up to 400 bar (5,000 psi) pneumatic, up to 1,600 bar (23,200 psi) hydraulic
Total measurement uncertainty to 0.008 % of differential pressure plus 0.0001 % (1 ppm) of static pressure
Factory calibration included as standard, traceable to national standards; with DKD/DAkkS calibration possible as an option
High long-term stability with recommended recalibration interval every five years
Masses manufactured from stainless steel and aluminium, can be adjusted to local gravity
Description
Pressure balances (dead-weight testers) are the most accurate instruments available on the market for the calibration of electronic or mechanical pressure measuring instruments. The direct measurement of the pressure (p = F/A), as well as the use of high-quality materials enable a very small measurement uncertainty, in conjunction with an excellent long-term stability.
Solutions for pressure, temperature, force and level measurement, flow measurement, calibration and SF6 gas solutions from WIKA are components integrated in the business processes of our customers.
