With an accuracy of <strong>0.01 % of reading<\/strong>, optionally available with an accuracy of up to <strong>0.006 % on request<\/strong>, the BH2-30B provides an excellent physical pressure reference for professional calibration laboratories, industrial metrology, quality assurance, research and development.<\/p>\n<p>The measuring range corresponds to <strong>10 to 3,000 kPa<\/strong> or <strong>2 to 400 psi<\/strong>. A particularly important advantage of the BH2-30B is its very low starting pressure of only 0.1 bar combined with a maximum pressure of 30 bar. This results in a measuring range ratio of 1:300 using only one piston-cylinder system.<\/p>\n<p>The BH2-30B operates according to the proven physical principle of a piston gauge. Calibrated masses generate a defined force on a precisely characterized piston-cylinder assembly. This force is balanced by the hydraulic pressure generated in the system, providing a stable and accurately defined reference pressure for comparison with the device under test.<\/p>\n<p>The system uses <strong>H15 oil<\/strong> as the pressure medium and incorporates a precision piston-cylinder assembly manufactured from treated steel.

laboratories requiring a physical reference standard for relatively low hydraulic pressures.<\/p>\n<h2>Ideal for Demanding Calibration Applications<\/h2>\n<p>The <strong>europascal BH2-30B<\/strong> is designed to test, adjust and calibrate mechanical and electronic pressure measuring instruments by comparison.<\/p>\n<p>Typical devices under test include:<\/p>\n<ul>\n<li>Precision pressure gauges<\/li>\n<li>Digital pressure gauges<\/li>\n<li>Reference pressure indicators<\/li>\n<li>Pressure sensors<\/li>\n<li>Pressure transmitters<\/li>\n<li>Pressure transducers<\/li>\n<li>Pressure switches<\/li>\n<li>Hydraulic pressure gauges<\/li>\n<li>Process pressure instruments<\/li>\n<li>Secondary pressure standards<\/li>\n<\/ul>\n<p>The low starting pressure of 0.1 bar is particularly advantageous for instruments with relatively small hydraulic measuring ranges.<\/p>\n<p>Typical DUT ranges can include:<\/p>\n<ul>\n<li>0 to 1 bar<\/li>\n<li>0 to 2.5 bar<\/li>\n<li>0 to 6 bar<\/li>\n<li>0 to 10 bar<\/li>\n<li>0 to 16 bar<\/li>\n<li>0 to 25 bar<\/li>\n<li>0 to 30 bar<\/li>\n<\/ul>\n<p>This makes the BH2-30B an interesting solution for laboratories that require a hydraulic reference standard at pressures where many conventional hydraulic deadweight testers begin at significantly higher values.<\/p>\n<h2>Pressure Range from 0.1 to 30 bar<\/h2>\n<p>The europascal BH2-30B covers a measuring range from:<\/p>\n<p><strong>0.1 to 30 bar<\/strong><\/p>\n<p>This corresponds to:<\/p>\n<p><strong>10 to 3,000 kPa<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>2 to 400 psi<\/strong><\/p>\n<p>The maximum pressure is:<\/p>\n<p><strong>30 bar \/ 3 MPa<\/strong><\/p>\n<p>The combination of a 0.1 bar minimum pressure and a 30 bar maximum pressure provides an impressive measuring range ratio of:<\/p>\n<p><strong>1:300<\/strong><\/p>\n<p>This complete pressure range is covered with a single piston-cylinder system.<\/p>\n<p>No change between two different pistons is required within the specified measuring range.<\/p>\n<h2>Accuracy of 0.01 % of Reading<\/h2>\n<p>The <strong>europascal BH2-30B Hydraulic Deadweight Tester<\/strong> provides a standard accuracy of:<\/p>\n<p><strong>0.01 % of reading<\/strong><\/p>\n<p>For particularly demanding applications, an enhanced accuracy of:<\/p>\n<p><strong>up to 0.006 %<\/strong><\/p>\n<p>is available on request.<\/p>\n<p>This performance makes the BH2-30B suitable not only for industrial pressure testing but also for demanding calibration laboratory applications.<\/p>\n<p>The complete measurement uncertainty of an actual calibration depends on additional influence quantities such as:<\/p>\n<ul>\n<li>Calibration of the piston-cylinder system<\/li>\n<li>Calibration of the mass set<\/li>\n<li>Effective piston area<\/li>\n<li>Local gravitational acceleration<\/li>\n<li>Temperature<\/li>\n<li>Density of the pressure medium<\/li>\n<li>Air buoyancy<\/li>\n<li>Environmental conditions<\/li>\n<li>Hydrostatic head correction<\/li>\n<li>Repeatability<\/li>\n<li>Resolution of the device under test<\/li>\n<\/ul>\n<p>These quantities should be considered when establishing the measurement uncertainty budget for high-quality pressure calibration.<\/p>\n<h2>Fundamental Piston Gauge Measurement Principle<\/h2>\n<p>The <strong>europascal BH2-30B<\/strong> operates according to the fundamental physical principle of a piston gauge.<\/p>\n<p>The basic 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 gravitational force generated by the calibrated masses is primarily described 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 pressure equation therefore becomes:<\/p>\n<p><strong>p = (m \u00d7 g) \/ A<\/strong><\/p>\n<p>The pressure is generated hydraulically and balanced against the force acting on the piston-cylinder assembly.<\/p>\n<p>When equilibrium is reached and the piston is operating in the correct position, the resulting pressure provides a highly stable physical reference for comparison with the connected device under test.<\/p>\n<h2>Precision Single-Piston Design<\/h2>\n<p>The europascal BH2-30B uses <strong>one piston-cylinder system<\/strong> across the complete measuring range from 0.1 to 30 bar.<\/p>\n<p>The typical piston area is:<\/p>\n<p><strong>78.4825 mm\u00b2<\/strong><\/p>\n<p>The piston is manufactured from:<\/p>\n<p><strong>treated steel<\/strong><\/p>\n<p>and the cylinder is also manufactured from:<\/p>\n<p><strong>treated steel<\/strong><\/p>\n<p>The precision piston-cylinder assembly represents the metrological heart of the deadweight tester.<\/p>\n<p>Using a single piston across the complete range simplifies operation because the user does not have to switch between different piston-cylinder assemblies during calibration.<\/p>\n<p>The manufacturer specifies a repeatability of <strong>3 \u00d7 10\u207b\u2075<\/strong> and a sensitivity of <strong>1 \u00d7 10\u207b\u2075<\/strong> for this high-performance deadweight tester concept.<\/p>\n<h2>Hydraulic Operation with H15 Oil<\/h2>\n<p>The <strong>europascal BH2-30B<\/strong> is a hydraulic deadweight tester.<\/p>\n<p>The specified pressure medium is:<\/p>\n<p><strong>H15 oil<\/strong><\/p>\n<p>with a fluid density of approximately:<\/p>\n<p><strong>845 kg\/m\u00b3<\/strong><\/p>\n<p>The hydraulic operating principle provides stable pressure generation and is particularly suitable for pressure instruments compatible with oil.<\/p>\n<p>The capstan generates pressure by displacing the hydraulic fluid. This pressure acts on the piston-cylinder assembly and is balanced by the applied calibrated masses.<\/p>\n<p>The BH2-30B therefore combines mechanical pressure generation with a fundamental physical reference principle.<\/p>\n<h2>CH2-125B Generator Base<\/h2>\n<p>The BH2-30B uses the:<\/p>\n<p><strong>CH2-125B generator base<\/strong><\/p>\n<p>The generator provides the hydraulic pressure required to bring the piston and applied masses into the appropriate operating position.<\/p>\n<p>The capstan allows the operator to increase or decrease the hydraulic pressure precisely.<\/p>\n<p>This provides fine control when approaching the equilibrium condition required for an accurate pressure measurement.<\/p>\n<h2>Stainless Steel Weight Sets<\/h2>\n<p>The mass set is a fundamental component of the deadweight tester.<\/p>\n<p>The BH2 series uses <strong>non-magnetic stainless steel masses<\/strong>.<\/p>\n<p>The ergonomic shape of the masses facilitates loading onto the weight carrier.<\/p>\n<p>Depending on the selected configuration, the masses can be marked according to the required pressure unit.<\/p>\n<p>Typical units include:<\/p>\n<p><strong>bar<\/strong><\/p>\n<p><strong>mbar<\/strong><\/p>\n<p><strong>kPa<\/strong><\/p>\n<p><strong>psi<\/strong><\/p>\n<p>and other available engineering units.<\/p>\n<p>The total mass of the weight set depends on the selected model and configuration.<\/p>\n<h2>Standard Gravity and Local Gravity<\/h2>\n<p>The force generated by the calibrated masses depends directly 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>However, actual gravitational acceleration varies depending on geographical location.<\/p>\n<p>The europascal BH2-30B can therefore be configured for either standard gravity or a specified local gravity value.<\/p>\n<p>This is important in high-accuracy pressure metrology because a change in gravitational acceleration directly changes the force generated by the calibrated masses.<\/p>\n<p>Correct consideration of local gravity can therefore improve the accuracy of the generated reference pressure.<\/p>\n<h2>Technical Highlights<\/h2>\n<p><strong>Model:<\/strong> europascal BH2-30B<\/p>\n<p><strong>Device type:<\/strong> Hydraulic Deadweight
