Pressure deformation, temperature and other correction quantities can become relevant when calculating the reference pressure with low measurement uncertainty.<\/p>\n<h2>Single-Piston High-Pressure Design<\/h2>\n<p>The <strong>europascal BH4-2500B<\/strong> uses:<\/p>\n<p><strong>one precision piston-cylinder system<\/strong><\/p>\n<p>The complete specified measuring range from 40 to 2,500 bar is generated using this single piston system.<\/p>\n<p>This provides straightforward operation because the operator does not need to switch between separate low-pressure and high-pressure pistons.<\/p>\n<p>The high-pressure piston-cylinder system is optimized for generating pressures up to 250 MPa.<\/p>\n<h2>High-Pressure Calibration up to 250 MPa<\/h2>\n<p>A maximum pressure of <strong>2,500 bar<\/strong> corresponds to:<\/p>\n<p><strong>250 MPa<\/strong><\/p>\n<p>This places the BH4-2500B clearly within the high-pressure calibration range.<\/p>\n<p>At these pressures, careful attention must be paid to the complete hydraulic measurement setup.<\/p>\n<p>This includes:<\/p>\n<ul>\n<li>Pressure-rated tubing<\/li>\n<li>High-pressure fittings<\/li>\n<li>Suitable adapters<\/li>\n<li>Correct pressure medium<\/li>\n<li>Device-under-test pressure rating<\/li>\n<li>Safe depressurization procedures<\/li>\n<li>Clean hydraulic connections<\/li>\n<\/ul>\n<p>All components connected to the pressure system must be suitable for the maximum applied pressure.<\/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 integrated platform provides functions such as:<\/p>\n<ul>\n<li>Motorized operation<\/li>\n<li>Dynamic visualization of piston position<\/li>\n<li>Automatic pressure calculation<\/li>\n<li>Automatic pressure display<\/li>\n<li>Different measurement units<\/li>\n<li>Operator assistance during calibration<\/li>\n<li>Recording of calibration results<\/li>\n<li>Computer data transfer<\/li>\n<\/ul>\n<p>The reference pressure itself continues to be generated physically by the calibrated masses and precision piston-cylinder system.<\/p>\n<p>Automation primarily simplifies operation, calculation, monitoring and documentation.<\/p>\n<h2>Motorized Mass Rotation<\/h2>\n<p>Free rotation of the piston helps minimize friction between the piston and cylinder.<\/p>\n<p>The BH4 platform provides:<\/p>\n<p><strong>motorized rotation of the mass system<\/strong><\/p>\n<p>This reduces the need for continuous manual rotation and improves operator convenience during repetitive calibration sequences.<\/p>\n<p>Motorized operation is particularly useful in high-pressure calibration procedures where stable operating conditions and consistent handling are important.<\/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 system provides:<\/p>\n<p><strong>dynamic visualization of the piston position<\/strong><\/p>\n<p>The operator can monitor the piston during calibration and determine whether it is operating within its appropriate working position.<\/p>\n<p>This simplifies the process of balancing the pressure generated by the pressure balance against the connected device under test.<\/p>\n<h2>Automatic Pressure Calculation and Display<\/h2>\n<p>The integrated calculator determines the generated reference pressure using the relevant pressure balance parameters.<\/p>\n<p>These can include:<\/p>\n<ul>\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 is displayed automatically.<\/p>\n<p>This reduces manual calculation effort and supports consistent calibration procedures.<\/p>\n<h2>Different Pressure Units with the Same Weight Set<\/h2>\n<p>The BH4 platform allows different pressure units to be used with the same physical calibration mass set.<\/p>\n<p>Depending on configuration, pressure can be displayed in units such as:<\/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 when calibrating devices from different manufacturers or for customers using different engineering units.<\/p>\n<h2>Calibration Result Recording<\/h2>\n<p>The <strong>europascal BH4-2500B<\/strong> supports digital 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>Calibration history<\/li>\n<li>Evaluation of devices under test<\/li>\n<li>Digital laboratory workflows<\/li>\n<\/ul>\n<p>Electronic recording also reduces the risk of transcription errors associated with manually transferring measurement values.<\/p>\n<h2>Computer Data Transfer<\/h2>\n<p>Calibration data can be transferred to a computer for further processing.<\/p>\n<p>This allows the BH4-2500B to be integrated into modern digital calibration workflows.<\/p>\n<p>For laboratories processing large numbers of calibration points, digital data transfer can significantly reduce manual documentation effort.<\/p>\n<h2>Hydraulic Operation with Oil<\/h2>\n<p>The <strong>europascal BH4-2500B<\/strong> is a hydraulic pressure balance operating with oil.<\/p>\n<p>Hydraulic operation is particularly suitable for generating very high pressures because hydraulic liquids have low compressibility compared with gases.<\/p>\n<p>At pressures up to 2,500 bar, cleanliness of the hydraulic circuit is especially important.<\/p>\n<p>Contamination can influence precision components and should therefore be minimized during installation, maintenance and connection of devices under test.<\/p>\n<h2>Calibration Masses<\/h2>\n<p>The BH4 series uses precision calibration masses to generate the force acting on the piston.<\/p>\n<p>The calibrated mass values form an essential part of the pressure reference.<\/p>\n<p>Together with the effective piston area and gravitational acceleration, the masses determine the generated reference pressure.<\/p>\n<p>AREMECA specifies stainless steel masses for the automatic BH4 series.<\/p>\n<h2>Standard or Local Gravity<\/h2>\n<p>The force generated by calibration 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>Actual gravitational acceleration varies geographically.<\/p>\n<p>For precision calibration, the appropriate local gravity value should therefore be considered.<\/p>\n<p>The instrument can be configured according to standard gravity or a specified customer gravity value.<\/p>\n<h2>Technical Highlights<\/h2>\n<p><strong>Model:<\/strong> europascal BH4-2500B<\/p>\n<p><strong>Device type:<\/strong> Automatic Hydraulic Deadweight
