700 bar<\/strong><\/p>\n<p>This corresponds to:<\/p>\n<p><strong>0.1 to 70 MPa<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>100 to 70,000 kPa<\/strong><\/p>\n<p>AREMECA specifies the imperial measuring range as:<\/p>\n<p><strong>10 to 10,000 psi<\/strong><\/p>\n<p>The maximum pressure is:<\/p>\n<p><strong>700 bar \/ 70 MPa<\/strong><\/p>\n<p>The dual piston configuration enables the BH2-700B DP to start at only 1 bar, whereas a single-piston system optimized for higher pressures typically has a higher minimum pressure.<\/p>\n<h2>Dual Piston Technology<\/h2>\n<p>The abbreviation <strong>DP<\/strong> stands for:<\/p>\n<p><strong>Dual Piston<\/strong><\/p>\n<p>The BH2-700B DP therefore incorporates:<\/p>\n<p><strong>2 precision piston-cylinder systems<\/strong><\/p>\n<p>Instead of attempting to cover the complete dynamic pressure range with a single piston, the instrument uses separate piston systems optimized for different pressure regions.<\/p>\n<p>This provides a wider usable pressure range while maintaining the physical advantages of a precision deadweight tester.<\/p>\n<h2>Low-Pressure Piston<\/h2>\n<p>The low-pressure piston is identified as:<\/p>\n<p><strong>BP \/ Low Pressure<\/strong><\/p>\n<p>The typical piston area is:<\/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 relatively large piston area allows lower pressures to be generated with practical calibration masses.<\/p>\n<p>This piston is therefore particularly important for extending the usable measuring range down to <strong>1 bar<\/strong>.<\/p>\n<h2>High-Pressure Piston<\/h2>\n<p>The high-pressure piston is identified as:<\/p>\n<p><strong>HP \/ High Pressure<\/strong><\/p>\n<p>The typical piston area is:<\/p>\n<p><strong>7.84068 mm\u00b2<\/strong><\/p>\n<p>The high-pressure piston is manufactured from:<\/p>\n<p><strong>tungsten carbide<\/strong><\/p>\n<p>The significantly smaller piston area enables higher pressures to be generated with manageable calibration masses.<\/p>\n<p>The HP piston provides the pressure capability required to reach the maximum pressure of:<\/p>\n<p><strong>700 bar \/ 70 MPa<\/strong><\/p>\n<h2>Why Two Piston Areas?<\/h2>\n<p>The relationship between force, piston area and pressure can be expressed as:<\/p>\n<p><strong>p = F \/ A<\/strong><\/p>\n<p>where:<\/p>\n<p><strong>p<\/strong> = pressure<br \/>\n<strong>F<\/strong> = force<br \/>\n<strong>A<\/strong> = effective piston area<\/p>\n<p>A large piston area is advantageous for generating relatively low pressures.<\/p>\n<p>A smaller piston area allows significantly higher pressures to be generated using the same applied force.<\/p>\n<p>The BH2-700B DP therefore combines two different piston areas:<\/p>\n<p><strong>LP: 78.4472 mm\u00b2<\/strong><\/p>\n<p><strong>HP: 7.84068 mm\u00b2<\/strong><\/p>\n<p>The area ratio is approximately:<\/p>\n<p><strong>10 : 1<\/strong><\/p>\n<p>This explains why the dual piston configuration can cover such a wide pressure range efficiently.<\/p>\n<h2>Physical Deadweight Tester Principle<\/h2>\n<p>The <strong>europascal BH2-700B DP<\/strong> generates pressure according to the physical piston gauge principle.<\/p>\n<p>The gravitational force produced by the calibration masses is approximately:<\/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>Combined with:<\/p>\n<p><strong>p = F \/ A<\/strong><\/p>\n<p>the simplified pressure equation becomes:<\/p>\n<p><strong>p = (m \u00d7 g) \/ A<\/strong><\/p>\n<p>The generated pressure is therefore fundamentally related to calibrated mass, gravitational acceleration and the effective area of the selected piston-cylinder system.<\/p>\n<p>For high-accuracy applications, additional corrections and influence quantities must be considered according to the calibration data.<\/p>\n<h2>Accuracy of 0.01 % of Reading<\/h2>\n<p>The standard accuracy of the <strong>europascal BH2-700B DP<\/strong> is:<\/p>\n<p><strong>0.01 % of reading<\/strong><\/p>\n<p>For more demanding applications, enhanced performance is available:<\/p>\n<p><strong>up to 0.006 % on request<\/strong><\/p>\n<p>The actual measurement uncertainty achieved during a calibration depends on the individual calibration data, environmental conditions, applied corrections, operating procedure and the device under test.<\/p>\n<h2>H40 Oil as Pressure Medium<\/h2>\n<p>The BH2-700B DP operates hydraulically with:<\/p>\n<p><strong>H40 oil<\/strong><\/p>\n<p>The manufacturer specifies a fluid density of approximately:<\/p>\n<p><strong>860 kg\/m\u00b3<\/strong><\/p>\n<p>Correct filling and venting of the hydraulic circuit are important for reliable operation.<\/p>\n<p>Trapped gas should be minimized because it can influence pressure generation, settling time and pressure stability.<\/p>\n<p>The compatibility of the pressure medium with the connected device under test should always be checked before calibration.<\/p>\n<h2>CH2-1250B Pressure Generator<\/h2>\n<p>The <strong>europascal BH2-700B DP<\/strong> uses the:<\/p>\n<p><strong>CH2-1250B pressure generator<\/strong><\/p>\n<p>The pressure generator provides the hydraulic pressure required to raise the piston and balance the applied calibration masses.<\/p>\n<p>The operator adjusts the pressure until the selected piston reaches its correct operating position and the system is in equilibrium.<\/p>\n<p>This provides a robust physical method for generating known reference pressures.<\/p>\n<h2>Calibration Masses<\/h2>\n<p>The BH2 series uses precision:<\/p>\n<p><strong>stainless steel calibration masses<\/strong><\/p>\n<p>The masses generate the gravitational force acting on the selected piston.<\/p>\n<p>Together with the effective piston area and gravitational acceleration, the calibrated mass values determine the generated pressure.<\/p>\n<p>Different pressure units can be selected for the principal mass set, including:<\/p>\n<ul>\n<li>bar<\/li>\n<li>psi<\/li>\n<li>kPa<\/li>\n<\/ul>\n<p>Additional or intermediate mass sets can also be selected for other units.<\/p>\n<h2>Standard or Local Gravity<\/h2>\n<p>The force generated by a calibration mass depends on gravitational acceleration.<\/p>\n<p>The conventional standard value is:<\/p>\n<p><strong>g = 9.80665 m\/s\u00b2<\/strong><\/p>\n<p>Because actual gravitational acceleration varies geographically, the BH2-700B DP can be configured for either:<\/p>\n<p><strong>standard gravity<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>a customer-specific local gravity value<\/strong><\/p>\n<p>Using the appropriate gravity value is important for precision pressure generation.<\/p>\n<h2>Measurement Uncertainty Contributions<\/h2>\n<p>The complete measurement uncertainty of a calibration with the BH2-700B DP can include contributions from:<\/p>\n<ul>\n<li>Calibration uncertainty of the masses<\/li>\n<li>Effective area of the LP piston<\/li>\n<li>Effective area of the HP piston<\/li>\n<li>Pressure coefficients<\/li>\n<li>Local gravitational acceleration<\/li>\n<li>Air buoyancy<\/li>\n<li>Piston-cylinder temperature<\/li>\n<li>Thermal expansion<\/li>\n<li>Hydraulic fluid properties<\/li>\n<li>Hydrostatic head difference<\/li>\n<li>Repeatability<\/li>\n<li>Sensitivity<\/li>\n<li>Pressure stability<\/li>\n<li>Resolution of the device under test<\/li>\n<li>Environmental conditions<\/li>\n<\/ul>\n<p>The uncertainty budget should use the actual calibration data for the selected piston-cylinder system.<\/p>\n<h2>Operating Conditions<\/h2>\n<p>AREMECA specifies an operating temperature range of:<\/p>\n<p><strong>18 to 28 \u00b0C<\/strong><\/p>\n<p>The manufacturer&#8217;s reference calibration conditions are:<\/p>\n<p><strong>Temperature: 20 \u00b0C<\/strong><\/p>\n<p><strong>Atmospheric pressure: 1013.25 hPa<\/strong><\/p>\n<p><strong>Relative humidity: 50 %<\/strong><\/p>\n<p><strong>Gravitational acceleration: 9.80665 m\/s\u00b2<\/strong><\/p>\n<p>When the instrument is operated under different conditions, the generated pressure can be recalculated according to the relevant variables.<\/p>\n<h2>Leveling and DUT Connection<\/h2>\n<p>Correct leveling is important for reliable piston gauge operation.<\/p>\n<p>The BH2 platform therefore includes:<\/p>\n<ul>\n<li>Leveling bubble<\/li>\n<li>Adjustable feet<\/li>\n<\/ul>\n<p>The connection for the instrument under test is a:<\/p>\n<p><strong>swivel G1\/2 standard connection<\/strong><\/p>\n<p>with other fittings available as options.<\/p>\n<p>All fittings, adapters and connected devices must be rated for the maximum applied hydraulic pressure.<\/p>\n<h2>Instrument Weight<\/h2>\n<p>The standard BH2-700B DP weighs approximately:<\/p>\n<p><strong>22 kg without calibration masses<\/strong><\/p>\n<p>With option OP0004 or OP0301, the manufacturer specifies approximately:<\/p>\n<p><strong>24 kg without calibration masses<\/strong><\/p>\n<p>The total system weight additionally depends on the selected calibration mass set.<\/p>\n<h2>Optional OP0004 Motorization<\/h2>\n<p>The <strong>europascal BH2-700B DP<\/strong> can be equipped with:<\/p>\n<p><strong>Option OP0004<\/strong><\/p>\n<p>This provides:<\/p>\n<ul>\n<li>Motorized rotation of the masses<\/li>\n<li>Piston position visualization using indicator lights<\/li>\n<\/ul>\n<p>Motorized rotation reduces manual intervention and can improve operating convenience during repetitive calibration procedures.<\/p>\n<h2>Optional OP0301 Calculator Module<\/h2>\n<p>For advanced calibration workflows, the BH2-700B DP can be equipped with:<\/p>\n<p><strong>Option OP0301<\/strong><\/p>\n<p>This provides functions including:<\/p>\n<ul>\n<li>Motorized operation<\/li>\n<li>Dynamic piston position visualization<\/li>\n<li>Environmental
