Fluke Calibration P3031 Pneumatic Deadweight Testers

The Fluke Calibration P3031 Pneumatic Deadweight Tester is a precision instrument designed for accurate pressure calibration in various industrial applications. With a pressure range of up to 2000 psi (140 bar), this deadweight tester offers exceptional accuracy, with a standard of ±0.015% of reading and an optional high-precision accuracy of ±0.008%. This ensures reliable and precise pressure measurements for a wide range of testing needs.

One of the key features of the P3031 is its gas-driven oil-lubricated piston/cylinder assembly. This innovative design minimizes susceptibility to performance issues arising from contamination or challenging operating environments. By directly applying the supply gas to the oil-lubricated pistons, the P3031 eliminates maintenance concerns typically associated with conventional high-pressure pneumatic deadweight testers.

The instrument incorporates a screw press for fine pressure control, allowing for meticulous adjustments during calibration procedures. The piston flotation indicator enhances operational awareness, and the mounted spirit level with adjustable feet ensures accurate positioning for optimal performance.

Constructed with Series 3 non-magnetic austenitic stainless steel weights, the P3031 guarantees durability and precision. The weights have a density of 7.8 g/cm³, providing stability and accuracy in pressure measurements. Additionally, fractional weights made of solution heat-treated aluminum are available as an option, with a density of 2.7 g/cm³, further expanding the calibration capabilities.

The P3031 Pneumatic Deadweight Tester comes equipped with a piston made of tungsten carbide and a cylinder made of martensitic steel, both materials known for their robustness and longevity. The coefficient of expansion is set at 16.5 ppm/°C, contributing to the stability and reliability of the instrument.

For ease of use, the instrument features test port adaptors in various sizes (1/8, 1/4, 3/8, and ½ NPT or BSP), providing versatility to accommodate different applications. The P3031 has a weight of 24 lbs and dimensions of 17.5 W x 12 D x 8.5 H, making it portable and convenient for on-site calibration.

To further enhance its capabilities, the P3031 offers compatibility with optional fractional weights, enabling measurements with a minimum standard weight increment of 1 psi (0.1 bar). The instrument also supports optional Krytox as the operating fluid for liquid-lubricated gas-operated models, making it suitable for oxygen-safe applications.

As an option, the P3031 can be bundled with PressCal Software, a Windows-based program that streamlines calibration procedures by applying necessary corrections. This software facilitates the storage of calibration details and the automatic generation of calibration certificates. PressCal is included as standard with all P3031 instruments with a high-precision accuracy of ±0.008%
