PRESSURE RANGE SELECTABLE SHEET Part # The BL511 Hydraulic Deadweight Tester is designed for a wide range of pressure calibration and measurement tasks, delivering exceptional accuracy and reliability. The heart of this tester is the precision-engineered piston-cylinder assembly, ensuring high accuracy and long-term stability. The space between the piston and cylinder is so minute that it can only be measured in controlled environmental conditions, reflecting the advanced manufacturing skills behind this device. Available with accuracies as high as 0.005% of reading, the BL511 is ideal for both laboratory and field use. Available in 0.02%, 0.01%, and 0.005% accuracy options Displays pressure regulator rod position for ease of use 3.5-inch LED display shows piston position, ambient temperature, and humidity Piston moving position indicator is easily calibrated Tungsten carbide piston and cylinder for high intensity, extreme hardness, and minimal thermal expansion (density: Five-year warranty for piston stability Pressure Calibration Laboratories Pressure Measurement in Field environments Balun Technology Co., Ltd Add: 1322, F/3, Bldg 1, 33 Zique Rd, Haidian, Beijing100095, China Piston Material: Tungsten carbide Cylinder Material: Tungsten carbide Mass Material: 304 Non-magnetic Stainless Steel Hydraulic Base Material: Aluminum Alloy Lubrication Medium: Mineral Oil (<25 MPa); Sebacate ( ≥ 25 MPa) Reservoir Volume: 400 ml Connector: Metric (NPT and BSP optional) Base Dimensions: 310 mm (H) x 480 mm (L) x 680 mm (D) Base Weight: 26 kg Power Supply: AC 220V, 50 Hz BL511 Hydraulic Deadweight Tester Base Piston cylinder unit Mass carrier 304 Non-magnetic Stainless Steel Mass Set User manual Transit case for safe transport OPTIONAL ACCESSORY AND SERVICE ■ BL511 / part number / accuracy / gravity value
