摘要：for the high-precision measurement of the pressure of fluid, such as gas andhydraulic fluid, the device comprises a vertical cylinder 1.a piston (2) is able to slide in the

cylinder with viscous friction, the pressure to be measured is applied to the upper face ofthe piston.the motor (4) means to rotate said piston in said cylinder.an electromagneticbalance with a precision (axis 3 for display is applied to measure the strength.and how toprovide the axis 3, the force applied to the piston by the pressure to measure, withlimited effort.
