Description

The Fluke Calibration P3123BAR Oil Operated Dual PCU Hydraulic Deadweight Tester, 1 to 350 bar is the culmination of over 50 years experience in the production and design of primary pressure standards. With features designed to improve accuracy and performance, increase reliability and simplify operation these deadweight testers can be used to calibrate virtually any pressure sensing device, including transducers, transmitters, gauges or pressure switches.

Each instrument is supplied with a detachable lid which makes it neat, compact and easily portable. The weight masses are stored in a high-quality case with a self locking mechanism to protect them during transit.

The P3123-BAR is provided with an accredited calibration report, weight mass details, M14 x 1.5, M20 X 1.5, 1/8 inch, 1/4 inch, 3/8 inch and 1/2 inch NPT and BSP female adaptors, operating fluid (where applicable) and spare seals.

The piston/cylinder assemblies are manufactured to the very highest standards and are provided standard with ISO/IEC 17025 accredited calibration reports.

Operating Principle

Deadweight testers are the primary standard for pressure measurement. Utilizing the well proven piston-gauge system consisting of a vertically mounted, precision lapped piston and cylinder assembly, accurately calibrated weight masses (Force) are loaded on the piston (Area), which rises freely within its cylinder. These weights balance the upward force created by the pressure within the system.

The pressure is measured when placed on a correctly spinning and floating piston. The total pressure measured is the summation of the weights, plus the piston weight carrier assembly.

Instrument Base

Pressure is generated and controlled by means of a high quality screw press located on the front of the tester. A built-in hand pump is included as standard for all hydraulic models to prime the system and accommodate large volume requirements.

Piston/Cylinder Assemblies

The piston/cylinder assembly is the heart of the P3123-BAR. The assemblies are manufactured from materials that provide stability, durability, and low thermal coefficients and distortion. Fluke Calibration's experience and knowledge of piston/cylinder production and calibration ensures the precision and performance required for today's demanding calibration requirements.

Weight Masses

Standard weight masses are series 3 non-magnetic austenitic stainless steel. Each mass is marked with a serial number and the nominal pressure value relative to the high- or low-pressure piston, when applicable. Optional fractional weights are stainless steel and/or solution heat treated aluminum.

Gravity Correction

Gravity varies significantly with geographical location and this variation has a direct effect on the force of the weights and the accuracy of the deadweight tester. The P3123-BAR can be trimmed to local gravity at no extra cost. If unspecified, instruments will be calibrated to Standard Gravity at 980.665 cm/s2.
