Druck Precision Pressure Standards

Model 2482 Ruska Differential Piston Gauge 

The Model 2482 is a high precision standard that provides unsurpassed performance in the field of differential pressure metrology at high static line pressures. The Model 2482 continues GE’s standard of excellence and innovation building on over 50 years of piston gauge manufacturing expertise. Designed to calibrate virtually any pressure device at high static line pressures the 2482 is a revolutionary breakthrough providing a fast, easy and accurate solution to what has historically been a time consuming and technique dependent process.

At the heart of the Model 2482 is a patented large cross-sectional area triple-axis differential piston assembly with axial symmetry less than one millionth of a meter. This unique assembly eliminates the need for a second deadweight piston and provides identification of the differential pressure as it is directly proportional to the mass load.
