Maintenance of the Gauge
•WinPrompt® provides simplicity and efficiency combined with accuracy and consistency in pressure generation and measurement using a deadweight gauge. It automatically converts pressure to mass and mass to pressure while correcting for piston temperature, head height, absolute and gauge references, local gravity, and air density. WinPrompt® can be operated from a single window for industrial use or from additional detailed windows available for the metrologist.
WinPrompt® Features:
•Stores calibration coefficients for working standards including piston/cylinder effective area, thermal coefficient of expansion, pressure deformation coefficients, and all calibrated mass values and associated density. It also stores all of the critical system and environmental parameters including local gravity, head corrections, and air density.
•Performs all necessary calculations of
•Computes the buoyant effect of the ambient air on the piston gauge masses and compensates accordingly.
•Creates calibration procedures for performing repetitive type calibrations. Procedures include sequence of pressure values, pressure reference, corrections, and window sizes and locations.
•Captures and saves information for direct import into Microsoft Word, Microsoft Excel, and other
•Additionally, WinPrompt® supports several interfaces to RUSKA deadweight gauges that can provide:
•Direct acquisition of float position, sink rate, piston temperature, vacuum, ambient temperature, barometric pressure, and humidity with continuous correction of calculated pressure.

Leaks
Leaks in the pressure system that is used with the gauge cannot be tolerated. Small leaks cause rapid piston fall rates and can create an error in the measured pressure. Every effort should be made to insure a
Maintenance of the Gauge
The gauge has no moving parts other than the Piston/Cylinder assemblies. The gauge requires no maintenance other than the periodic cleaning of the piston/cylinder assemblies and replacing
