The RUSKA 7050 Precision Pressure Indicator uses force-balanced, fused-quartz
Bourdon tube technology to provide the precise measurement of pressure.
In Measure mode, the PPI measures pressure. Typically, Measure mode applications are
found in research laboratories, wind tunnel testing, power plant testing, and bubbler tank
volume accountancy systems. It is also used to monitor barometric pressures, vacuum
systems, and differential pressure devices.
Features
The following features are available on all RUSKA 7050 PPIs.
Fused-Quartz Bourdon Tube Technology
(5 - 2500 psi full scale ranges), RUSKA’s force-balanced, fused-quartz Bourdon tube
sensor makes use of the stability, high elasticity, low hysteresis, and excellent fatigue
strength of fused quartz. This time-proven technology eliminates the need for gear trains,
bearings, shafts, and other moving parts that can wear out or introduce hysteresis or
deadband into the process.
Mercury-Free
All components in the PPI are mercury-free.
NIST Traceability
All PPIs are calibrated per ANSI/NCSL Z-540-1-1994 using RUSKA deadweight gauges
that are directly traceable to the National Institute of Standards and Technology (NIST).
Universal Power Supply
The PPI’s universal power supply accepts AC voltages between 100-120 VAC and
220-240 VAC. To “reconfigure” the PPI for use in another country, the user simply
changes the power cord.
