combination of two piston-cylinder systems provides a particularly broad useful measuring range while maintaining excellent metrological performance.<\/p>\n<h2>Dual Piston Design for a Wide Measuring Range<\/h2>\n<p>A key feature of the <strong>europascal BH2-300B DP<\/strong> is its dual-piston configuration.<\/p>\n<p>The instrument incorporates:<\/p>\n<p><strong>Low-pressure piston (LP): 78.4472 mm\u00b2<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>High-pressure piston (HP): 15.6852 mm\u00b2<\/strong><\/p>\n<p>The larger effective area of the low-pressure piston enables lower pressures to be generated with practical mass loads.<\/p>\n<p>For higher pressures, the smaller high-pressure piston provides the required pressure using manageable calibrated masses.<\/p>\n<p>This principle allows one pressure balance system to cover a significantly broader measuring range than would otherwise be practical with a single piston-cylinder system.<\/p>\n<p>The dual-piston configuration is particularly useful for calibration laboratories that need to calibrate both lower-pressure and higher-pressure instruments while minimizing the number of separate reference standards required.<\/p>\n<h2>Pressure Range from 1 to 300 bar<\/h2>\n<p>The europascal BH2-300B DP covers a total measuring range from:<\/p>\n<p><strong>1 to 300 bar<\/strong><\/p>\n<p>This corresponds to:<\/p>\n<p><strong>100 to 30,000 kPa<\/strong><\/p>\n<p>or approximately:<\/p>\n<p><strong>10 to 4,000 psi<\/strong><\/p>\n<p>The maximum pressure is therefore:<\/p>\n<p><strong>300 bar \/ 30 MPa<\/strong><\/p>\n<p>This provides an overall measuring range ratio of:<\/p>\n<p><strong>1:300<\/strong><\/p>\n<p>The wide range makes the BH2-300B DP suitable for numerous common industrial pressure ranges, including instruments with nominal ranges such as 10 bar, 25 bar, 40 bar, 60 bar, 100 bar, 160 bar, 250 bar and 300 bar.<\/p>\n<h2>Accuracy of 0.01 % of Reading<\/h2>\n<p>The <strong>europascal BH2-300B DP Dual Piston Deadweight Tester<\/strong> provides a standard accuracy of:<\/p>\n<p><strong>0.01 % of reading<\/strong><\/p>\n<p>For applications with particularly demanding metrological requirements, an enhanced accuracy of:<\/p>\n<p><strong>up to 0.006 %<\/strong><\/p>\n<p>is available on request.<\/p>\n<p>The complete measurement uncertainty of an actual calibration depends on additional influence quantities.<\/p>\n<p>These can include:<\/p>\n<ul>\n<li>Calibration of the mass set<\/li>\n<li>Effective piston areas<\/li>\n<li>Local gravitational acceleration<\/li>\n<li>Air buoyancy<\/li>\n<li>Piston-cylinder temperature<\/li>\n<li>Pressure deformation<\/li>\n<li>Density of the hydraulic fluid<\/li>\n<li>Hydrostatic head correction<\/li>\n<li>Repeatability<\/li>\n<li>Resolution of the device under test<\/li>\n<li>Environmental conditions<\/li>\n<\/ul>\n<p>These quantities should be considered when establishing a measurement uncertainty budget for high-accuracy pressure calibration.<\/p>\n<h2>Fundamental Piston Gauge Measurement Principle<\/h2>\n<p>The <strong>europascal BH2-300B DP<\/strong> operates according to the fundamental physical measurement principle of a piston gauge.<\/p>\n<p>Pressure is derived from a defined force acting on a characterized effective piston area.<\/p>\n<p>The fundamental relationship is:<\/p>\n<p><strong>p = F \/ A<\/strong><\/p>\n<p>where:<\/p>\n<p><strong>p<\/strong> = generated pressure<br \/>\n<strong>F<\/strong> = force acting on the piston<br \/>\n<strong>A<\/strong> = effective piston area<\/p>\n<p>The force generated by calibrated masses is primarily determined by:<\/p>\n<p><strong>F = m \u00d7 g<\/strong><\/p>\n<p>where:<\/p>\n<p><strong>m<\/strong> = applied mass<br \/>\n<strong>g<\/strong> = gravitational acceleration<\/p>\n<p>The simplified relationship therefore becomes:<\/p>\n<p><strong>p = (m \u00d7 g) \/ A<\/strong><\/p>\n<p>Because the BH2-300B DP incorporates two different piston areas, the same fundamental equation applies to both piston-cylinder systems.<\/p>\n<p>The appropriate calibrated effective area is used depending on which piston is operating.<\/p>\n<p>For high-accuracy pressure calibration, additional corrections can be applied for temperature, pressure deformation, air buoyancy, gravity and hydrostatic head.<\/p>\n<h2>Low-Pressure Piston<\/h2>\n<p>The low-pressure piston of the BH2-300B DP has a typical piston area of:<\/p>\n<p><strong>78.4472 mm\u00b2<\/strong><\/p>\n<p>The low-pressure piston is manufactured from:<\/p>\n<p><strong>treated steel<\/strong><\/p>\n<p>Its comparatively large piston area allows lower hydraulic pressures to be generated using practical mass loads.<\/p>\n<p>This is an important advantage of the dual-piston concept because a single high-pressure piston with a much smaller area would require very small masses to generate equivalent low pressures.<\/p>\n<p>The low-pressure piston therefore extends the useful measuring range of the system toward lower pressure values.<\/p>\n<h2>High-Pressure Piston<\/h2>\n<p>The high-pressure piston has a typical piston area of:<\/p>\n<p><strong>15.6852 mm\u00b2<\/strong><\/p>\n<p>The high-pressure piston is manufactured from:<\/p>\n<p><strong>tungsten carbide<\/strong><\/p>\n<p>Tungsten carbide provides excellent hardness, wear resistance and dimensional stability and is therefore particularly suitable for precision piston components.<\/p>\n<p>The smaller effective area enables the BH2-300B DP to generate pressures up to:<\/p>\n<p><strong>300 bar \/ 30 MPa<\/strong><\/p>\n<p>without requiring an impractically large mass stack.<\/p>\n<p>The combination of the low-pressure and high-pressure pistons is the central advantage of the DP configuration.<\/p>\n<h2>Hydraulic Operation with H40 Oil<\/h2>\n<p>The <strong>europascal BH2-300B DP<\/strong> is a hydraulic deadweight tester.<\/p>\n<p>The specified standard pressure medium for this model is:<\/p>\n<p><strong>H40 oil<\/strong><\/p>\n<p>with a fluid density of approximately:<\/p>\n<p><strong>860 kg\/m\u00b3<\/strong><\/p>\n<p>This is an important model-specific difference compared with several lower-pressure BH2 instruments that use H15 oil.<\/p>\n<p>The hydraulic fluid transfers pressure from the generator to the selected piston-cylinder assembly and the connected device under test.<\/p>\n<p>For high-accuracy measurements, the density of the pressure medium should be considered when a vertical height difference exists between the reference level of the deadweight tester and the reference level of the device under test.<\/p>\n<h2>CH2-1250B Pressure Generator<\/h2>\n<p>The europascal BH2-300B DP uses the:<\/p>\n<p><strong>CH2-1250B generator base<\/strong><\/p>\n<p>The hydraulic pressure generator enables the operator to generate and finely regulate the required pressure.<\/p>\n<p>The capstan displaces hydraulic fluid through the system until the pressure generated by the hydraulic circuit balances the force applied to the selected piston-cylinder assembly.<\/p>\n<p>Fine pressure control allows the piston to be positioned correctly for accurate measurements.<\/p>\n<p>The CH2-1250B generator, dual piston-cylinder system and calibrated weight set together form the complete physical pressure reference.<\/p>\n<h2>Stainless Steel Weight Sets<\/h2>\n<p>The calibrated masses form another essential part of the BH2-300B DP measurement system.<\/p>\n<p>The BH2 series uses:<\/p>\n<p><strong>stainless steel weights<\/strong><\/p>\n<p>The masses have an ergonomic shape designed to facilitate loading onto the weight carrier.<\/p>\n<p>The main weight set can be supplied according to the required engineering unit.<\/p>\n<p>Available units include:<\/p>\n<p><strong>bar<\/strong><\/p>\n<p><strong>kPa<\/strong><\/p>\n<p><strong>psi<\/strong><\/p>\n<p>and other available pressure units.<\/p>\n<p>Intermediate weight sets and additional principal weight sets can also be selected depending on the calibration application.<\/p>\n<h2>Standard Gravity and Local Gravity<\/h2>\n<p>The pressure generated by a deadweight tester depends directly on gravitational acceleration.<\/p>\n<p>The conventional standard gravitational acceleration is:<\/p>\n<p><strong>g = 9.80665 m\/s\u00b2<\/strong><\/p>\n<p>However, the actual value varies according to geographical location.<\/p>\n<p>The BH2-300B DP can therefore be configured for either standard gravity or a customer-specified local gravity value.<\/p>\n<p>For high-accuracy calibration, this is an important consideration because a deviation in gravitational acceleration directly changes the force produced by the calibrated masses.<\/p>\n<h2>Technical

with <strong>option OP0004<\/strong>.<\/p>\n<p>This option provides motorized rotation of the masses together with visualization of the piston position using indicator lights.<\/p>\n<p>Correct rotation and piston position are important for stable piston gauge operation.<\/p>\n<p>Motorization reduces manual intervention during repetitive calibration procedures, while piston position indicators assist the operator in establishing the appropriate measurement condition.<\/p>\n<p>With option OP0004 installed, the instrument weight without the mass set increases from approximately <strong>22 kg to 24 kg<\/strong>.<\/p>\n<h2>Optional Automatic Pressure Calculation<\/h2>\n<p>For laboratories requiring more advanced automation, the BH2-300B DP can be equipped with <strong>option

SP<\/h2>\n<p>The BH2-300B is available in single-piston and dual-piston configurations.<\/p>\n<p>The abbreviation:<\/p>\n<p><strong>SP = Single Piston<\/strong><\/p>\n<p>while:<\/p>\n<p><strong>DP = Dual Piston<\/strong><\/p>\n<p>Both concepts can cover pressure ranges up to 300 bar, but the dual-piston system provides two optimized piston-cylinder assemblies.<\/p>\n<p>The <strong>BH2-300B DP<\/strong> is therefore particularly attractive when excellent usability over a broad pressure range is required.<\/p>\n<p>The larger low-pressure piston supports precise operation toward the lower end of the range, while the smaller high-pressure piston is optimized for higher pressures.<\/p>\n<p>This combination provides greater flexibility than a conventional single-piston configuration.<\/p>\n<h2>BH2 Dual Piston Series<\/h2>\n<p>The europascal Aremeca BH2 High Performance family includes several dual-piston models.<\/p>\n<p>These include:<\/p>\n<p><strong>BH2-300B
