MODEL BL512 HIGH PRESSURE DEADWEIGHT TESTER The model BL512 high pressure deadweight testers are applicable in very wide variety of pressure calibration and measurement tasks. The pressure ranges is up to 800MPa. The piston cylinder assembly is the heart of the dead weight tester and responsible for its high accuracy. We manufactures piston cylinder with accuracies from 0.05% up to 0.005% of reading. To give an idea of the manufacturing skills, the space between the piston and the cylinder is in the um range and can only be measured in a climate room. ■ With piston rotation electric motor ■ 3.5 inch LED displays piston location, ambient temperature and humidity ■ 16mm thick aluminum alloy base ■ Piston position can be easily calibrated ■ Modulzied piston and cylinder unit ■ The piston and cylinder is made of the high intensity, extreme hardness and lowest thermal expansion tungsten carbide, which density is 15 g/cm3, thermal coefficient of expansion is 16.5 ppm /°C ■ Pressure calibration labs ■ Pressure measurement in field ■ Piston material: Tungsten carbide ■ Cylinder material: Tungsten carbide ■ Mass set material: 304 non-magnetic stainless steel ■ Hydraulic base material: Aluminium alloy ■ Transforming and lubrication medium: Sebacate ■ Connector: Metric (NPT and BSP is option) ■ Pressure units available: MPa, bar, PSI PRESSURE SELECTABLE SHEET ■ BL512 High Pressure deadweight tester base ■ Piston cylinder unit ■ 304 non-magnetic stainless steel mass set OPTIONAL ACCESSORIES AND SERVICES ORDERING MODEL NUMBER Balun Technology Co., Ltd T: +86-10-6240 6768 E: [email protected] Add: 1322, F/3, Bldg 1,33 Zique Rd, Haidian, Beijing 100095, China F: +86-10-8978 0678 W:
