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>Industrial process instruments<\/li>\n<li>Secondary pressure standards<\/li>\n<\/ul>\n<p>The wide measuring range makes the BH2-300B particularly useful for calibration laboratories working with a broad selection of industrial pressure instruments.<\/p>\n<p>Common ranges such as 10 bar, 25 bar, 40 bar, 60 bar, 100 bar, 160 bar, 250 bar and 300 bar can be covered with one pressure standard.<\/p>\n<h2>Pressure Range from 1 to 300 bar<\/h2>\n<p>The europascal BH2-300B covers a measuring range from:<\/p>\n<p><strong>1 to 300 bar<\/strong><\/p>\n<p>This corresponds to:<\/p>\n<p><strong>100 to 30,000 kPa<\/strong><\/p>\n<p>or:<\/p>\n<p><strong>15 to 4,000 psi<\/strong><\/p>\n<p>The maximum pressure is therefore:<\/p>\n<p><strong>300 bar \/ 30 MPa<\/strong><\/p>\n<p>The complete measuring range is covered by a single piston-cylinder assembly.<\/p>\n<p>This is the fundamental difference between the <strong>BH2-300B Single Piston<\/strong> and the <strong>BH2-300B DP Dual Piston<\/strong> version.<\/p>\n<p>For laboratories that prefer a straightforward single-piston configuration, the BH2-300B provides an excellent combination of range, accuracy and ease of operation.<\/p>\n<h2>Accuracy of 0.01 % of Reading<\/h2>\n<p>The <strong>europascal BH2-300B Single Piston Deadweight Tester<\/strong> provides a standard accuracy of:<\/p>\n<p><strong>0.01 % of reading<\/strong><\/p>\n<p>For particularly demanding metrological applications, enhanced accuracy of:<\/p>\n<p><strong>up to 0.006 %<\/strong><\/p>\n<p>is available on request.<\/p>\n<p>The complete measurement uncertainty of a 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>Density of the hydraulic fluid<\/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>These quantities should be considered when establishing the measurement uncertainty budget for high-accuracy pressure calibration.<\/p>\n<h2>Fundamental Piston Gauge Measurement Principle<\/h2>\n<p>The <strong>europascal BH2-300B<\/strong> operates according to the fundamental physical measurement principle of a piston gauge.<\/p>\n<p>Pressure is generated by applying a precisely defined force to a characterized 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 pressure relationship therefore becomes:<\/p>\n<p><strong>p = (m \u00d7 g) \/ A<\/strong><\/p>\n<p>For precision measurements, additional corrections may be applied for air buoyancy, local gravitational acceleration, piston temperature, pressure deformation and hydrostatic head.<\/p>\n<p>Because pressure is derived from physical quantities such as mass, gravity and effective piston area, the deadweight tester provides excellent long-term stability as a reference pressure standard.<\/p>\n<h2>Precision Single-Piston Design<\/h2>\n<p>The defining characteristic of the europascal BH2-300B is its <strong>single-piston configuration<\/strong>.<\/p>\n<p>The complete measuring range from 1 to 300 bar is covered using one precision piston-cylinder system.<\/p>\n<p>The typical piston area is:<\/p>\n<p><strong>7.84875 mm\u00b2<\/strong><\/p>\n<p>The piston is manufactured from:<\/p>\n<p><strong>tungsten carbide<\/strong><\/p>\n<p>while the cylinder is manufactured from:<\/p>\n<p><strong>treated steel<\/strong><\/p>\n<p>Tungsten carbide provides excellent hardness, dimensional stability and wear resistance, making it particularly suitable for high-precision piston components.<\/p>\n<p>Using only one piston simplifies everyday operation and avoids the need to change between low-pressure and high-pressure piston-cylinder systems.<\/p>\n<h2>Hydraulic Operation with H40 Oil<\/h2>\n<p>The <strong>europascal BH2-300B<\/strong> is a hydraulic deadweight tester.<\/p>\n<p>The specified pressure medium is:<\/p>\n<p><strong>H40 oil<\/strong><\/p>\n<p>with a density of approximately:<\/p>\n<p><strong>860 kg\/m\u00b3<\/strong><\/p>\n<p>The hydraulic pressure medium transfers the generated pressure to both the precision piston-cylinder assembly and the connected device under test.<\/p>\n<p>The use of oil provides stable pressure generation and makes the system suitable for pressure instruments that are compatible with hydraulic calibration media.<\/p>\n<p>For precision calibration, the density of the pressure medium should be considered when a vertical height difference exists between the reference level of the deadweight tester and the reference level of the device under test.<\/p>\n<p>The resulting hydrostatic head can then be included in the pressure calculation.<\/p>\n<h2>CH2-1250B Pressure Generator<\/h2>\n<p>The europascal BH2-300B uses the:<\/p>\n<p><strong>CH2-1250B generator base<\/strong><\/p>\n<p>The generator allows the operator to generate and precisely regulate hydraulic pressure.<\/p>\n<p>The capstan displaces the hydraulic fluid through the system until the generated pressure balances the force applied to the piston by the calibrated masses.<\/p>\n<p>Fine pressure adjustment allows the piston to be brought into its correct operating position.<\/p>\n<p>The CH2-1250B pressure generator, piston-cylinder system and calibrated mass set together form the complete physical pressure standard.<\/p>\n<h2>Stainless Steel Weight Sets<\/h2>\n<p>The calibrated masses are an essential part of the BH2-300B measurement system.<\/p>\n<p>The masses are manufactured from:<\/p>\n<p><strong>stainless steel<\/strong><\/p>\n<p>and feature an ergonomic design for convenient handling.<\/p>\n<p>The principal weight set can be supplied according to the required pressure unit.<\/p>\n<p>Available units include:<\/p>\n<p><strong>bar<\/strong><\/p>\n<p><strong>kPa<\/strong><\/p>\n<p><strong>psi<\/strong><\/p>\n<p>and other available engineering units.<\/p>\n<p>Intermediate weight sets and additional principal weight sets for different pressure units are also available.<\/p>\n<p>This allows the BH2-300B to be configured according to the requirements of the calibration laboratory.<\/p>\n<h2>Standard Gravity and Local Gravity<\/h2>\n<p>The generated pressure depends directly on gravitational acceleration.<\/p>\n<p>The conventional standard gravitational acceleration is:<\/p>\n<p><strong>g = 9.80665 m\/s\u00b2<\/strong><\/p>\n<p>However, actual gravitational acceleration varies according to geographical location.<\/p>\n<p>The BH2-300B can therefore be supplied for either standard gravity or a specified local gravity value.<\/p>\n<p>This is important for high-accuracy calibration because the force generated by the calibrated masses is directly proportional to gravitational acceleration.<\/p>\n<p>Correct consideration of local gravity contributes to reducing measurement uncertainty.<\/p>\n<h2>Technical Highlights<\/h2>\n<p><strong>Model:<\/strong>
