Model 2456/WinPrompt® Piston Gauge Monitor and Software 

Accounting for environmental factors when performing piston gauge calibrations is an important but labour intensive process. Ruska’s Model 2456 piston gauge monitor (PGM) and WinPrompt calibration software help automate this process. The Model 2456 enhances measurement precision and consistency of critical piston gauge parameters including piston gauge temperature, float position, sink rate, air density, vacuum and other variables.

Temperature: The Model 2456 uses precision four-wire platinum resistance thermometers (PRTs) to monitor the  piston gauge temperature. It actively monitors two PRTs and stores coefficients for up to ten. This minimizes the risk of damage to sensitive PRTs by allowing the operator to move the Model 2456 to another piston gauge location without moving the PRTs.
