Consequently, the same gravitational force generated by the calibration masses produces different pressures depending on which piston is used.<\/p>\n<p>This allows a wide overall pressure range while retaining practical mass increments at both low and high pressures.<\/p>\n<h2>Accuracy of 0.01 %<\/h2>\n<p>The <strong>europascal BH4-600B DP<\/strong> provides a specified accuracy of:<\/p>\n<p><strong>0.01 %<\/strong><\/p>\n<p>This makes the instrument suitable for demanding hydraulic pressure calibration applications.<\/p>\n<p>The complete measurement uncertainty of an actual calibration additionally depends on the individual influence quantities of the pressure balance and calibration setup.<\/p>\n<p>Relevant contributions can include:<\/p>\n<ul>\n<li>Calibration of the mass set<\/li>\n<li>Effective area of the selected piston<\/li>\n<li>Pressure coefficient<\/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>Hydraulic fluid properties<\/li>\n<li>Hydrostatic head difference<\/li>\n<li>Repeatability<\/li>\n<li>Resolution of the device under test<\/li>\n<li>Environmental conditions<\/li>\n<\/ul>\n<p>Because the BH4-600B DP uses two piston-cylinder systems, the correct calibration parameters for the selected piston must be used when calculating the generated pressure.<\/p>\n<h2>Fundamental Piston Gauge Measurement Principle<\/h2>\n<p>The <strong>europascal BH4-600B DP Dual Piston Deadweight Tester<\/strong> operates according to the physical piston gauge principle.<\/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 gravitational force generated by the calibration 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 pressure relationship is therefore:<\/p>\n<p><strong>p = (m \u00d7 g) \/ A<\/strong><\/p>\n<p>The dual-piston concept uses two different effective piston areas.<\/p>\n<p>A larger effective area is advantageous for generating lower pressures, while a smaller effective area allows substantially higher pressures to be generated with the same mass force.<\/p>\n<p>For precision calibration, additional corrections can be considered for local gravity, air buoyancy, piston-cylinder temperature, pressure deformation and hydrostatic head.<\/p>\n<h2>Low-Pressure Piston from 1 to 60 bar<\/h2>\n<p>The first piston-cylinder system is optimized for lower pressures and covers:<\/p>\n<p><strong>1 to 60 bar<\/strong><\/p>\n<p>The larger effective piston area allows practical calibration mass increments to be used at relatively low hydraulic pressures.<\/p>\n<p>This dedicated low-pressure piston is a major advantage compared with the BH4-600B SP single-piston version, which starts at 2 bar.<\/p>\n<p>The DP configuration therefore extends the overall lower pressure limit to:<\/p>\n<p><strong>1 bar<\/strong><\/p>\n<h2>High-Pressure Piston from 10 to 600 bar<\/h2>\n<p>The second piston-cylinder system is optimized for the higher pressure range:<\/p>\n<p><strong>10 to 600 bar<\/strong><\/p>\n<p>The smaller effective piston area allows higher pressures to be generated using the common mass set.<\/p>\n<p>The maximum pressure is:<\/p>\n<p><strong>600 bar<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>60 MPa<\/strong><\/p>\n<p>This combination provides a particularly broad pressure range within one automatic pressure balance.<\/p>\n<h2>Overlapping Range from 10 to 60 bar<\/h2>\n<p>The two piston systems overlap between:<\/p>\n<p><strong>10 and 60 bar<\/strong><\/p>\n<p>Within this range, pressure points can be generated using either piston system, depending on the calibration procedure and configuration.<\/p>\n<p>This overlap ensures continuity between the low-pressure and high-pressure ranges and provides additional flexibility for professional calibration laboratories.<\/p>\n<h2>Automatic BH4 Platform<\/h2>\n<p>The BH4 series combines the physical measurement principle of a deadweight tester with automatic operator assistance.<\/p>\n<p>The platform integrates functions for:<\/p>\n<ul>\n<li>Motorized operation<\/li>\n<li>Dynamic piston position visualization<\/li>\n<li>Automatic pressure calculation<\/li>\n<li>Automatic pressure display<\/li>\n<li>Different pressure units<\/li>\n<li>Calibration result recording<\/li>\n<li>Computer data transfer<\/li>\n<\/ul>\n<p>The reference pressure itself continues to be generated physically by calibrated masses acting on the selected piston-cylinder system.<\/p>\n<p>The automation primarily simplifies operation, calculation and documentation.<\/p>\n<h2>Integrated Motorized Operation<\/h2>\n<p>Free rotation of the piston helps reduce friction effects between the piston and cylinder.<\/p>\n<p>The <strong>europascal BH4-600B DP<\/strong> provides integrated motorized operation, reducing the need for manual rotation of the piston and mass system.<\/p>\n<p>This is particularly useful for repetitive calibration procedures involving many measurement points.<\/p>\n<p>The automatic functionality helps provide consistent operating conditions while reducing operator workload.<\/p>\n<h2>Dynamic Piston Position Visualization<\/h2>\n<p>Correct piston position is essential for reliable deadweight tester operation.<\/p>\n<p>The BH4 platform therefore provides:<\/p>\n<p><strong>dynamic piston position visualization<\/strong><\/p>\n<p>The operator can monitor the position of the active piston during calibration and determine whether it is operating within the appropriate working range.<\/p>\n<p>This simplifies balancing and provides greater convenience compared with purely manual piston position observation.<\/p>\n<h2>Automatic Pressure Calculation and Display<\/h2>\n<p>The BH4 platform assists with calculating the reference pressure generated by the selected piston and applied calibration masses.<\/p>\n<p>This is particularly useful for a dual-piston pressure balance because the calculation must use the correct effective area and calibration parameters for the active piston-cylinder system.<\/p>\n<p>The system can consider relevant parameters such as:<\/p>\n<ul>\n<li>Selected piston-cylinder system<\/li>\n<li>Applied calibration masses<\/li>\n<li>Effective piston area<\/li>\n<li>Gravitational acceleration<\/li>\n<li>Environmental parameters<\/li>\n<li>Relevant correction quantities<\/li>\n<\/ul>\n<p>The resulting reference pressure can then be displayed directly to the operator.<\/p>\n<h2>Different Pressure Units<\/h2>\n<p>The automatic calculation system allows the generated pressure to be displayed in different units.<\/p>\n<p>Depending on the configuration, these can include:<\/p>\n<ul>\n<li>bar<\/li>\n<li>kPa<\/li>\n<li>MPa<\/li>\n<li>psi<\/li>\n<li>kg\/cm\u00b2<\/li>\n<\/ul>\n<p>This provides flexibility for calibration laboratories working with pressure instruments from different industries and countries.<\/p>\n<h2>Recording of Calibration Results<\/h2>\n<p>The <strong>europascal BH4-600B DP<\/strong> supports recording of calibration results.<\/p>\n<p>This can simplify:<\/p>\n<ul>\n<li>Calibration documentation<\/li>\n<li>Measurement traceability<\/li>\n<li>Quality assurance<\/li>\n<li>Evaluation of devices under test<\/li>\n<li>Calibration history<\/li>\n<li>Digital laboratory workflows<\/li>\n<\/ul>\n<p>Electronic data handling can also reduce the risk of transcription errors associated with manual recording.<\/p>\n<h2>Computer Data Transfer<\/h2>\n<p>Calibration data can be transferred to a computer.<\/p>\n<p>This allows the BH4-600B DP to be incorporated into modern digital calibration workflows.<\/p>\n<p>For laboratories calibrating many devices or measurement points, computer data transfer can reduce manual documentation work and simplify subsequent processing of calibration results.<\/p>\n<h2>Hydraulic Operation with Oil<\/h2>\n<p>The <strong>europascal BH4-600B DP<\/strong> is a hydraulic pressure balance operating with:<\/p>\n<p><strong>oil<\/strong><\/p>\n<p>Hydraulic operation provides efficient pressure transmission throughout the complete 1 to 600 bar pressure range.<\/p>\n<p>Correct filling and venting of the hydraulic circuit are important because trapped gas can affect pressure generation and settling behavior.<\/p>\n<p>Compatibility between the pressure medium, device under test and wetted components should always be verified.<\/p>\n<h2>Standard Gravity and Local Gravity<\/h2>\n<p>The force generated by calibration masses 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>Actual gravitational acceleration varies according to geographical location.<\/p>\n<p>For precision calibration, an appropriate local gravity value can therefore be relevant.<\/p>\n<p>The pressure balance can be configured for standard gravity or a customer-specific local gravity value according to the calibration requirements.<\/p>\n<h2>Technical
