The Fluke Calibration P3032KPA Gas Operated Liquid Lubricated Pneumatic Deadweight Tester, 100 to 14000 kPa is the culmination of over 50 years of experience in the production and design of primary pressure standards. With features designed to improve accuracy and performance, increase reliability, and simplify operation, this deadweight tester can be used to calibrate virtually any pressure sensing device, including transducers, transmitters, gauges or pressure switches.

The Fluke Calibration P3032-KPA is supplied with a detachable lid that makes it neat, compact and easily portable. The masses are stored in a high-quality case with a self-locking mechanism to protect them during transit. This unit is also provided with an accredited calibration certificate, M14X1.5, M20X1.5, 1/8, 1/4, 3/8, and 1/2 NPT and BSP female adaptors, operating fluid (where applicable) and spare seals. Its piston/cylinder assemblies are manufactured to the very highest standards and are supplied with accredited calibration reports with stated instrumental measurement uncertainties.

Operating Principle

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

Piston/Cylinder Assemblies

The piston/cylinder assembly is the heart of the P3032-KPA, 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 ensure the precision and performance required for today's demanding calibration requirements.

Masses

Standard masses are series 3 non-magnetic austenitic stainless steel. Each mass is marked with the serial number of the instrument and the nominal pressure value relative to the highor low-pressure piston, when applicable. The masses for the vacuum ranges and the optional fine increment masses are stainless steel and/or 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 P3032-KPA deadweight tester. This instrument can be calibrated to local gravity at no extra cost; unspecified, it will be calibrated to Standard Gravity at 980.665 cm/s2.

Gas Supply

The Fluke Calibration P3032-KPA is fitted with a 1/4 inch NPT female external supply port for connection to the gas supply source. A compressed gas bottle (nitrogen or dry air) fitted with a pressure regulator is recommended. Ten percent above the maximum pressure is required.

PressCal Software

The PressCal Windows-based software program allows users to easily apply all necessary corrections to enhance the P3032-KPA's performance. Calibration details are then stored and/or used to automatically to create a calibration certificate. The use of PressCal allows for an improved accuracy of up to 0.008%.
