MODEL BL505 DUAL PISTON PRESSURE BALANCE Pressure range: -0.1MPa to 0.25MPa / 0.6MPa / 1 MPa Accuracy 0.01 class 0.02 class 0.05 class Mass material: 304 stainless steel Base material: Aluminium alloy Medium: Dry air or pure nitrogen Gravity: Customize to local or standard 9.80665 m/s² Pressure connector: Metric Power supply: 100-240VAC Base dimension: 310 mm (H) x 680 mm (L) x 480 mm (D) Base weight: 26kg SPECIFICATION Piston material: Tungsten Carbide Cylinder material: Tungsten Carbide Calibrate spring tube pressure gauges and precision spring tube vacuum gauges. Test mercury pressure gauges and noncorrosive industrial pressure gauges. The model BL505 dual piston pressure balance is based on the principle of static pressure, which achieves a force balance system through a master piston and a slave piston. When the system is under positive pressure, the balance of the two pistons is disrupted. The slave piston rises and the master piston falls. In order to restore the original balance of the system, several weights must be added to the slave piston to restore balance. At this time, the weight of the added weights is the pressure value of the tested system. Vice versa, if vacuum is introduced to the system, the salve piston falls and the master piston rises. At this time, several weights must be added to the master piston to balance it, and the weight of the added weights is the vacuum value of the tested system. Motor drives the weight rotating. Front LED shows piston position, real temperature and humidity. The oil pressure regulator and oil gas isolator are equipped with needle valves.
