Datasheet
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. On the contrary, if negative pressure 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.
