Model 2413 DPI Cell
The differential pressure cell has two pressure chambers separated by a thin metal diaphragm. A difference in pressure in the two chambers causes a deflection of the diaphragm which is sensed by an LVDT circuit. The output from the LVDT is displayed on the indicator.
Model 2456 Piston Gauge Monitor
Accounting for environmental factors when performing piston gauge calibrations is an important but labor intensive process. Ruska's Model 2456 Piston Gauge Monitor (PGM) and WinPrompt software help automate this process.
Gas Deadweight Gauge to 1000 psi - Model 2465
The Model 2465 Gas Piston Gauge has a long history of serving national standard laboratories, commercial industry and government organizations as a gas piston gauge standard for over 40 years. Now, Ruska offers the next step in the development of the Model 2465. With a new autofloat controller, operator intervention is reduced to simply applying the mass load, while still providing the highest level of performance available in a gas piston gauge: 0.0015% of reading.
Gas Deadweight Gauge - Model 2468 Pitot/Static Primary Standard
The model 2468 Pitot Static Primary Standard is specifically designed for calibrating today's high performance flight line and Air Data Test Systems. Time-proven materials, hand craftsmanship, and a lineage of intercomparisons to national standards laboratories at the highest level are coupled with new automated technology to make the Model 2468 Pitot Static Primary Standard the world's choice for calibrating Air Data Test Systems.
Gas Deadweight Gauge to 3000 psi - Model 2470
The Model 2470 Gas Piston Gauge is capable of generating gauge pressures from 0.2 to 3000 psig with an accuracy of 0.0010% of reading to 100 psig and 0.0025% of reading to 3000 psig. Operating beyond the typical upper pressure limits of existing gas operated piston gauges, the Model 2470 functions easily for this pressure range due to Ruska instrument's unique ability to manufacture gas-operated / gas-lubricated piston/cylinder assemblies.
High Line Differential Piston Gauge - Model 2470DP
The Model 2470DP Differential Gas Piston Gauge is a versatile, all-in-one instrument developed for the primary purpose of calibrating differential transmitters, transducers and gauges at elevated static (line) pressures.
