dual-piston design is particularly advantageous for laboratories that need to calibrate both lower-pressure and high-pressure hydraulic instruments without using two completely separate deadweight testers.<\/p>\n<h2>Dual Piston Design for an Exceptional Measuring Range<\/h2>\n<p>The defining characteristic of the <strong>europascal BH4-1200B DP<\/strong> is its dual-piston configuration.<\/p>\n<p>The system provides two pressure ranges:<\/p>\n<p><strong>Low-pressure piston: 1 to 60 bar<\/strong><\/p>\n<p>and:<\/p>\n<p><strong>High-pressure piston: 20 to 1,200 bar<\/strong><\/p>\n<p>The two ranges overlap between 20 and 60 bar.<\/p>\n<p>This overlap provides flexibility when selecting the most appropriate piston-cylinder system for a particular calibration point.<\/p>\n<p>The larger low-pressure piston enables lower hydraulic pressures to be generated with practical calibration masses, while the smaller high-pressure piston allows pressures up to 1,200 bar to be generated without requiring an impractically large mass stack.<\/p>\n<p>This is the fundamental advantage of the dual-piston principle.<\/p>\n<h2>Pressure Range from 1 to 1,200 bar<\/h2>\n<p>Considering both piston-cylinder systems, the BH4-1200B DP provides an overall pressure coverage from:<\/p>\n<p><strong>1 to 1,200 bar<\/strong><\/p>\n<p>The two working ranges are:<\/p>\n<p><strong>1 to 60 bar \u2013 low-pressure piston<\/strong><\/p>\n<p><strong>20 to 1,200 bar \u2013 high-pressure piston<\/strong><\/p>\n<p>The maximum pressure corresponds to:<\/p>\n<p><strong>1,200 bar<\/strong><\/p>\n<p><strong>120 MPa<\/strong><\/p>\n<p>or approximately:<\/p>\n<p><strong>17,400 psi<\/strong><\/p>\n<p>The low-pressure range from 1 to 60 bar corresponds to approximately:<\/p>\n<p><strong>100 to 6,000 kPa<\/strong><\/p>\n<p>while the high-pressure range from 20 to 1,200 bar corresponds to:<\/p>\n<p><strong>2,000 to 120,000 kPa<\/strong><\/p>\n<p>This broad pressure coverage makes the BH4-1200B DP particularly versatile for professional pressure calibration.<\/p>\n<h2>Accuracy of 0.01 %<\/h2>\n<p>The <strong>europascal BH4-1200B DP Automatic Dual Piston Deadweight Tester<\/strong> provides a specified accuracy of:<\/p>\n<p><strong>0.01 %<\/strong><\/p>\n<p>This enables precise calibration across the two hydraulic pressure ranges.<\/p>\n<p>The complete measurement uncertainty of an actual calibration additionally depends on the individual uncertainty contributions of the reference standard and the device under test.<\/p>\n<p>Relevant influence quantities can include:<\/p>\n<ul>\n<li>Calibration of the mass set<\/li>\n<li>Effective area of the selected piston<\/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 density<\/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>For demanding calibration applications, these quantities should be evaluated in accordance with the applicable measurement uncertainty model.<\/p>\n<h2>Fundamental Piston Gauge Measurement Principle<\/h2>\n<p>The <strong>europascal BH4-1200B DP<\/strong> operates according to the fundamental physical principle of a piston gauge.<\/p>\n<p>Pressure is determined from a known force acting on a precisely 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 gravitational force generated by the 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 pressure relationship therefore becomes:<\/p>\n<p><strong>p = (m \u00d7 g) \/ A<\/strong><\/p>\n<p>Because the BH4-1200B DP incorporates two piston-cylinder assemblies, the appropriate effective piston area is used according to the selected pressure range.<\/p>\n<p>For precision calibration, additional corrections can be included for local gravity, air buoyancy, piston temperature, pressure deformation and hydrostatic head.<\/p>\n<h2>Why Use Two Pistons?<\/h2>\n<p>A deadweight tester generates pressure according to the ratio between force and effective piston area.<\/p>\n<p>A larger piston area is advantageous at lower pressures because useful pressure values can be generated using practical calibration masses.<\/p>\n<p>At high pressures, however, a large piston would require an extremely heavy mass stack.<\/p>\n<p>A smaller piston area solves this problem.<\/p>\n<p>The <strong>BH4-1200B DP<\/strong> therefore combines:<\/p>\n<p><strong>a larger piston for the low-pressure range<\/strong><\/p>\n<p>with:<\/p>\n<p><strong>a smaller piston for the high-pressure range<\/strong><\/p>\n<p>This enables the instrument to cover an overall range of 1 to 1,200 bar while maintaining practical operation.<\/p>\n<p>For a calibration laboratory, this can reduce the number of separate pressure standards required.<\/p>\n<h2>Automatic Pressure Calculation<\/h2>\n<p>One of the major advantages of the <strong>europascal BH4-1200B DP<\/strong> is its integrated calculator.<\/p>\n<p>The BH4 system provides:<\/p>\n<ul>\n<li>Automatic calculation of generated pressure<\/li>\n<li>Automatic pressure display<\/li>\n<li>Consideration of the selected piston<\/li>\n<li>Support for different pressure units<\/li>\n<li>Operator assistance<\/li>\n<li>Reduced manual calculation effort<\/li>\n<li>Improved efficiency during repetitive calibration<\/li>\n<\/ul>\n<p>With a conventional manual deadweight tester, the operator must determine the reference pressure from the applied masses, effective piston area and relevant correction factors.<\/p>\n<p>The BH4 concept simplifies this process by integrating calculation functionality directly into the system.<\/p>\n<h2>Dynamic Piston Position Visualization<\/h2>\n<p>Correct piston position is essential for reliable piston gauge operation.<\/p>\n<p>The BH4 system therefore provides:<\/p>\n<p><strong>dynamic visualization of the piston position<\/strong><\/p>\n<p>This enables the operator to monitor the piston position during calibration and establish the correct operating condition.<\/p>\n<p>Visual assistance is particularly valuable during repetitive calibration procedures because it reduces the need for continuous manual observation.<\/p>\n<h2>Motorized Operation<\/h2>\n<p>The automatic BH4 platform includes:<\/p>\n<p><strong>motorized operation of the rotating mass system<\/strong><\/p>\n<p>Rotation helps minimize friction effects between the piston and cylinder and supports free piston movement.<\/p>\n<p>Motorization improves operating convenience and provides consistent rotation during calibration.<\/p>\n<p>Together with dynamic piston position visualization, this significantly reduces the manual intervention normally required when operating a conventional deadweight tester.<\/p>\n<h2>Automatic Calibration Functions<\/h2>\n<p>The BH4 platform combines several functions within one calibration system:<\/p>\n<p><strong>Motorization<\/strong><\/p>\n<p><strong>Dynamic piston position visualization<\/strong><\/p>\n<p><strong>Sensors<\/strong><\/p>\n<p><strong>Calculator<\/strong><\/p>\n<p><strong>Automatic pressure calculation<\/strong><\/p>\n<p><strong>Calibration data traceability<\/strong><\/p>\n<p><strong>Result recording<\/strong><\/p>\n<p><strong>Computer data transfer<\/strong><\/p>\n<p>The physical reference pressure continues to be generated by the piston-cylinder system and calibrated masses.<\/p>\n<p>The electronic functions simplify operation, calculation and documentation without replacing the fundamental physical measurement principle.<\/p>\n<h2>Recording of Calibration Results<\/h2>\n<p>The <strong>europascal BH4-1200B DP<\/strong> supports:<\/p>\n<p><strong>recording of calibration results<\/strong><\/p>\n<p>This is particularly useful for professional laboratories performing repetitive calibration procedures.<\/p>\n<p>Recorded data can support:<\/p>\n<ul>\n<li>Calibration documentation<\/li>\n<li>Measurement traceability<\/li>\n<li>Quality assurance<\/li>\n<li>Evaluation of the device under test<\/li>\n<li>Calibration history<\/li>\n<li>Digital laboratory workflows<\/li>\n<\/ul>\n<p>The integration of measurement data handling helps reduce manual documentation work.<\/p>\n<h2>Computer Data Transfer<\/h2>\n<p>Calibration results can be:<\/p>\n<p><strong>transferred to a computer<\/strong><\/p>\n<p>This enables the BH4-1200B DP to be integrated into digital calibration workflows.<\/p>\n<p>Data transfer reduces the need to manually copy measurement values and can therefore reduce potential transcription errors.<\/p>\n<p>For laboratories calibrating a large number of devices, this can provide a significant improvement in efficiency.<\/p>\n<h2>Different Pressure Units with the Same Weight Set<\/h2>\n<p>The integrated calculation system enables:<\/p>\n<p><strong>different pressure units to be used with the same set of weights<\/strong><\/p>\n<p>This is particularly useful for calibration laboratories working with instruments from different countries or industries.<\/p>\n<p>Depending on the configuration, pressure values can be handled 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>The system therefore provides greater flexibility than a purely mechanical pressure balance with masses dedicated exclusively to one pressure unit.<\/p>\n<h2>Stainless Steel Calibration Masses<\/h2>\n<p>The BH4 series uses:<\/p>\n<p><strong>stainless steel calibration masses<\/strong><\/p>\n<p>The calibrated masses generate the gravitational force acting on the selected piston.<\/p>\n<p>Their calibration and long-term stability are important elements of the pressure measurement system.<\/p>\n<p>The generated pressure depends on the calibrated mass values, gravitational acceleration and effective area of the selected piston-cylinder assembly.<\/p>\n<h2>Standard Gravity and Local Gravity<\/h2>\n<p>The conventional standard value for gravitational acceleration is:<\/p>\n<p><strong>g = 9.80665 m\/s\u00b2<\/strong><\/p>\n<p>However, actual gravity varies according to geographical location.<\/p>\n<p>For high-accuracy deadweight tester calibration, this effect must be considered because gravitational acceleration directly affects the force generated by the calibration masses.<\/p>\n<p>The system can therefore be configured according to standard gravity or a customer-specific gravity value.<\/p>\n<h2>Hydraulic Operation with Oil<\/h2>\n<p>The <strong>europascal BH4-1200B DP<\/strong> is a hydraulic deadweight tester.<\/p>\n<p>The pressure medium is:<\/p>\n<p><strong>oil<\/strong><\/p>\n<p>Hydraulic operation is particularly suitable for the broad pressure range extending to 1,200 bar.<\/p>\n<p>Correct filling and venting of the system are important. Trapped air should be minimized because its compressibility can affect pressure generation and settling behavior.<\/p>\n<p>Compatibility between the hydraulic medium and the device under test should always be checked before calibration.<\/p>\n<h2>Technical Highlights<\/h2>\n<p><strong>Model:<\/strong> europascal BH4-1200B DP<\/p>\n<p><strong>Device type:<\/strong> Automatic Dual Piston Hydraulic
