General Information
The RUSKA 7252 uses force-balanced, fused-quartz Bourdon tube technology to provide
the precise measurement of pressure. During normal operation, the Calibrator performs in
either Measure mode or Control mode.
In Control mode, the Calibrator simultaneously measures and controls pressure. Control
mode is commonly used in the calibration and testing of pressure gauges, transducers,
pressure switches, and production pressure instruments.
In Measure mode, the Calibrator 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.
The RUSKA 7252 has two full scale pressure ranges and two pressure controllers
integrated into one instrument.
Features
The following features are available on all RUSKA 7252 Calibrators.
Fused-Quartz Bourdon Tube Technology
The fused-quartz Bourdon tube technology sensor features 0.36 – 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 Calibrator are mercury-free.
NIST Traceability
All RUSKA 7252 and 7252i Calibrators are calibrated using RUSKA deadweight gauges
which are directly traceable to the National Institute of Standards and Technology (NIST).
A NVLAP accredited calibration certificate is provided standard with the instrument.
