General Information
The RUSKA 7750i ADTS uses force-balanced, fused-quartz Bourdon tube technology to
provide the precise measurement of pressure. During normal operation, the ADTS
performs in either Measure mode or Control mode.
In Control mode, the ADTS simultaneously measures and controls pressure. Control
mode is commonly used in the calibration and testing of air data computers, altimeters,
airspeed indicators, rate of climb indicators, pressure gauges, transducers, pressure
switches, and production pressure instruments.
In measure mode, the ADTS measures pressure. It can be used to monitor barometric
pressures, vacuum systems, and differential pressure devices.
The RUSKA 7750i has two full-scale pressure ranges and two pressure controllers
integrated into one instrument.
Features
The following features are available on all RUSKA 7750i ADTSs.
Fused-Quartz Bourdon Tube Technology
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 dead band into the process.
NIST Traceability
All ADTS’s are calibrated using RUSKA’s deadweight gauges that are directly traceable
to the National Institute of Standards and Technology (NIST). NVLAP Accredited
calibration reports are provided standard with the instrument.
Universal Power Supply
The ADTS’s universal power supply accepts AC voltages between 100 – 120 VAC and
220 – 240 VAC. To “reconfigure” the ADTS for use in another country, the user simply
changes the power cord.
