Range<\/h2>\n<p>The most important feature of the <strong>europascal BH2-400B DP<\/strong> is its dual-piston configuration.<\/p>\n<p>The instrument provides two measuring ranges:<\/p>\n<p><strong>Low-pressure piston: 1 to 60 bar<\/strong><\/p>\n<p><strong>High-pressure piston: 5 to 400 bar<\/strong><\/p>\n<p>The two ranges overlap between <strong>5 and 60 bar<\/strong>.<\/p>\n<p>This overlap provides considerable flexibility when selecting the piston-cylinder system for a particular calibration point.<\/p>\n<p>The complete pressure coverage therefore extends from:<\/p>\n<p><strong>1 to 400 bar<\/strong><\/p>\n<p>The dual-piston concept allows these two measuring ranges to be generated using the same calibration weight set.<\/p>\n<p>This provides an important practical advantage for calibration laboratories because a broad pressure range can be covered without requiring two completely separate deadweight testers.<\/p>\n<h2>Measuring Ranges in bar, PSI and kPa<\/h2>\n<p>The two pressure ranges are specified as follows:<\/p>\n<h3>Low-Pressure Piston<\/h3>\n<p><strong>1 to 60 bar<\/strong><\/p>\n<p><strong>10 to 800 psi<\/strong><\/p>\n<p><strong>100 to 6,000 kPa<\/strong><\/p>\n<h3>High-Pressure Piston<\/h3>\n<p><strong>5 to 400 bar<\/strong><\/p>\n<p><strong>50 to 5,000 psi<\/strong><\/p>\n<p><strong>500 to 40,000 kPa<\/strong><\/p>\n<p>The maximum pressure is:<\/p>\n<p><strong>400 bar \/ 40 MPa<\/strong><\/p>\n<p>This wide measuring range makes the BH2-400B DP suitable for a broad selection of hydraulic pressure calibration tasks.<\/p>\n<h2>Accuracy of 0.01 %<\/h2>\n<p>The <strong>europascal BH2-400B DP Precise Dual Piston Deadweight Tester<\/strong> provides a specified accuracy of:<\/p>\n<p><strong>0.01 %<\/strong><\/p>\n<p>This makes the system suitable for demanding calibration applications involving pressure gauges, sensors, transmitters and other industrial pressure measuring instruments.<\/p>\n<p>The complete measurement uncertainty of an actual calibration additionally depends on relevant influence quantities such as:<\/p>\n<ul>\n<li>Calibration of the masses<\/li>\n<li>Effective piston area<\/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<\/li>\n<li>Repeatability<\/li>\n<li>Resolution of the device under test<\/li>\n<li>Environmental conditions<\/li>\n<\/ul>\n<p>These quantities should be considered when establishing a measurement uncertainty budget for high-accuracy pressure calibration.<\/p>\n<h2>Fundamental Piston Gauge Measurement Principle<\/h2>\n<p>The <strong>europascal BH2-400B DP<\/strong> operates according to the fundamental physical principle of a piston gauge.<\/p>\n<p>Pressure is generated by applying a precisely defined force to a 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 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 relationship therefore becomes:<\/p>\n<p><strong>p = (m \u00d7 g) \/ A<\/strong><\/p>\n<p>For precision measurements, additional corrections can be applied for local gravity, air buoyancy, piston-cylinder temperature, pressure deformation and hydrostatic head.<\/p>\n<p>Because the BH2-400B DP contains two piston-cylinder assemblies, the appropriate effective area is used according to the selected pressure range.<\/p>\n<h2>Why Use Two Pistons?<\/h2>\n<p>The pressure generated by a deadweight tester depends on the ratio between applied force and effective piston area.<\/p>\n<p>For low pressures, a relatively large piston area is advantageous. It allows useful pressure values to be generated with practical calibration masses.<\/p>\n<p>For higher pressures, a smaller piston area is advantageous because the same mass generates a significantly higher pressure.<\/p>\n<p>The <strong>BH2-400B DP<\/strong> combines both principles in one instrument:<\/p>\n<p><strong>Larger piston \u2192 1 to 60 bar<\/strong><\/p>\n<p><strong>Smaller piston \u2192 5 to 400 bar<\/strong><\/p>\n<p>The result is an exceptionally broad measuring range with a useful overlap between both piston systems.<\/p>\n<p>This is especially valuable for calibration laboratories that regularly work with devices covering very different pressure ranges.<\/p>\n<h2>One Weight Set for Two Measuring Ranges<\/h2>\n<p>An important advantage of the dual-piston concept is that:<\/p>\n<p><strong>two measuring ranges can be obtained from the same weight set.<\/strong><\/p>\n<p>The operator selects the appropriate piston-cylinder system according to the required pressure.<\/p>\n<p>Because the two pistons have different effective areas, the same calibrated mass produces different pressures depending on which piston is used.<\/p>\n<p>This allows the BH2-400B DP to cover an overall pressure range from 1 to 400 bar while keeping the mass system practical and manageable.<\/p>\n<h2>Ideal for Pressure Gauge Calibration<\/h2>\n<p>The <strong>europascal BH2-400B DP<\/strong> is particularly suitable for calibration of mechanical and electronic pressure measuring instruments.<\/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>Hydraulic 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>Process pressure instruments<\/li>\n<li>Secondary pressure standards<\/li>\n<\/ul>\n<p>Common nominal pressure ranges such as 6 bar, 10 bar, 16 bar, 25 bar, 40 bar, 60 bar, 100 bar, 160 bar, 250 bar and 400 bar can therefore be covered with one physical pressure standard.<\/p>\n<h2>Hydraulic Operation with Oil<\/h2>\n<p>The <strong>europascal BH2-400B DP<\/strong> is a hydraulic deadweight tester.<\/p>\n<p>Oil is used as the pressure transmission medium.<\/p>\n<p>Hydraulic operation provides stable pressure generation and is particularly suitable for industrial pressure calibration up to several hundred bar.<\/p>\n<p>Correct filling and venting of the hydraulic system are important for reliable operation.<\/p>\n<p>Trapped gas should be minimized because its compressibility can affect pressure generation, settling time and system behavior.<\/p>\n<p>Compatibility between the hydraulic medium and the device under test should always be checked before calibration.<\/p>\n<h2>Stainless Steel Calibration Masses<\/h2>\n<p>The BH2 series uses high-quality:<\/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>The generated reference pressure is therefore directly related to:<\/p>\n<ul>\n<li>Calibrated mass<\/li>\n<li>Local gravitational acceleration<\/li>\n<li>Effective piston area<\/li>\n<li>Relevant correction quantities<\/li>\n<\/ul>\n<p>The mass set can be configured for different pressure units according to the customer&#8217;s requirements.<\/p>\n<p>Available units include:<\/p>\n<p><strong>bar<\/strong><\/p>\n<p><strong>psi<\/strong><\/p>\n<p><strong>kPa<\/strong><\/p>\n<p>and other available engineering units.<\/p>\n<p>Intermediate weight sets and additional basic weight sets for different units are also available.<\/p>\n<h2>Standard Gravity and Local Gravity<\/h2>\n<p>The force generated by a calibration mass 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, local gravitational acceleration varies depending on geographical location.<\/p>\n<p>The BH2-400B DP can therefore be configured according to:<\/p>\n<p><strong>standard gravity<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>a customer-specific gravity value<\/strong><\/p>\n<p>For high-accuracy pressure calibration, using the correct gravity value is important because it directly influences the force applied to the piston.<\/p>\n<h2>Optional Motorization \u2013 OP0004<\/h2>\n<p>The <strong>europascal BH2-400B DP<\/strong> can be expanded with option:<\/p>\n<p><strong>OP0004<\/strong><\/p>\n<p>This option provides:<\/p>\n<ul>\n<li>Motorized rotation of the masses<\/li>\n<li>Piston position visualization<\/li>\n<li>LED indication<\/li>\n<li>Increased operator convenience<\/li>\n<li>Improved support during repetitive calibration procedures<\/li>\n<\/ul>\n<p>Rotation helps minimize friction effects between piston and cylinder and supports stable piston operation.<\/p>\n<p>The position visualization helps the operator determine whether the piston is within its correct working position.<\/p>\n<h2>Optional Calculator Module \u2013 OP0301<\/h2>\n<p>For laboratories requiring greater automation, the BH2-400B DP can be equipped with:<\/p>\n<p><strong>OP0301<\/strong><\/p>\n<p>This option adds:<\/p>\n<ul>\n<li>Motorization<\/li>\n<li>Dynamic piston position visualization<\/li>\n<li>Sensors<\/li>\n<li>Calculator module<\/li>\n<li>Automatic pressure calculation<\/li>\n<li>Automatic display of generated pressure<\/li>\n<li>Environmental parameter consideration<\/li>\n<li>Calibration data traceability<\/li>\n<li>Computer data transfer<\/li>\n<li>Support for calibration certificate generation<\/li>\n<\/ul>\n<p>This transforms the conventional BH2 pressure balance into a significantly more automated calibration system.<\/p>\n<p>It is particularly useful for laboratories performing frequent calibrations where manual calculations and documentation would otherwise require additional operator time.<\/p>\n<h2>Technical Highlights<\/h2>\n<p><strong>Model:<\/strong>
