The Fluke Calibration P3200 Models are available in single or dual piston formats for increased operating ranges. Units can be supplied in psi, bar, kgf/cm2, and MPa. The Fluke Calibration P3100 are robust instruments are highly accurate, quick and easy to use. Units feature a built-in priming pump for large volume applications, piston flotation indicators and a high quality screw press for fine pressure control.

The Fluke Calibration P3200 is the culmination of over 50 years of experience in the production and design of high performance 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.

The Fluke Calibration P3200 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. All Fluke Calibration P3200 units are provided with a traceable certificate of accuracy, weight mass details, 1/8 inch, 1/4 inch, 3/8 inch and 1/2 inch NPT or BSP female adaptors, operating fluid (where applicable) and spare seals. The piston/cylinder assemblies are manufactured to the very highest standards with certified accuracies traceable to international standards laboratories such as the National Institute of Standards and Technology (NIST).

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 pres-sure 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
There are three basic variations in the hydraulic offering; single low pressure, single high pressure and dual piston models. 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 each deadweight tester. They are manufactured from materials that provide stability, durability, and low thermal coefἀcients and distortion. Our experience and knowledge of piston/cylinder production and calibration ensure 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 the serial number of the instru-ment 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. Each instrument can be calibrated to local gravity at no extra cost. If unspecified, instruments will be calibrated to Standard Gravity at 980.665 cm/s2.
