Produktoversikt: P3100 HP Series Very High-Pressure Hydraulic Deadweight Tester

The P3100 HP Series very high-pressure hydraulic deadweight tester is the culmination of over 65 years of experience in the design and manufacturing of primary pressure standards. The P3100 HP Series can be used to calibrate virtually any high-pressure sensing device including transducers, transmitters, gauges or pressure switches. It provides a convenient means of testing high pressure instruments for calibration accuracy.

Instrument base

The P3100 HP Series very high-pressure hydraulic deadweight tester incorporates the “Piston Gauge” principle, in which an applied pressure within the system, balances a known mass applied to a piston of known effective area. The unit comprises a base plate onto which is mounted a high-pressure manifold, a piston/cylinder unit (PCU), a fluid reservoir, a variable volume 4-arm spindle pressure generating system with a lever-style priming pump and a safety relief valve (which protects both the low- and high-pressure systems from accidental overpressure). A built-in test station allows quick and secure connection of the device under test. Adjustable leveling feet and an external level vial ensure proper leveling for optimal performance. Additionally, a piston float reference indicator helps the user easily identify the optimal “mid-float” position, enhancing measurement precision. The whole assembly is contained within a strong GRP housing.

Piston/Cylinder

At the heart of every deadweight tester is the piston-cylinder assembly—and in the P3100 HP Series, this critical component is engineered for superior performance. Each piston is crafted from high-grade tungsten carbide, offering exceptional long-term stability, outstanding durability, and ultra-low coefficients of thermal expansion and pressure distortion. The result: consistently accurate performance you can rely on, year after year.

Weight Sets

The P3100 HP Series includes standard weights made from Series 3 non-magnetic stainless steel for superior stability and corrosion resistance. Each mass is individually marked with the instrument’s serial number and its corresponding nominal pressure value. Choose from pressure units in psi, bar, or MPa. For added flexibility, optional PressCal software allows support for additional pressure units to suit your calibration needs.

Gravity Correction

Because gravity varies by location—and even small differences can affect high-accuracy pressure calibrations—the P3100 HP Series can be calibrated to your specific local gravity at no additional cost. If local gravity is not specified, instruments are calibrated to the standard reference of 980.665 cm/s², ensuring consistent and reliable performance out of the box.
