TESTER: PITOT STATIC,DIGITAL, 55KFT,650 KNOTS & 600FT/MIN

DPS350 digital air data testers.MEETS RVSM ACCURACY REQUIREMENTS. The Barfield DPS350 air


data tester is a microprocessor-based unit using the latest in transducer technology. The DPS350 operates


similar to Barfield_x0012_s 1811 Series testers but the transducer technology used is virtually immune to the costly


repairs generally experienced by analog instruments. Software containing a programmable protection limit


feature has been incorporated into the DPS350 to insulate the aircraft instruments from damage caused by


negative airspeed and over pressurization conditions. Limit protection is provided by computer actuated


solenoid valves that safeguard aircraft altitude, airspeed, rate of climb/decent and mach instruments. The


high accuracy and a stability (see Air Data Specifications for details) exhibited by the transducers qualifies


the DPS350 for use on aircraft being certified for reduced vertical separation minimum (RVSM) operation


and increases the calibration interval from 30 days to once a year. The simple menu driven digital display


calculates and displays altitude, vertical speed, airspeed, EPR and other measurements in various units of


measure, including: ft., m., kts., km./hr., Mach, ft./min., m./min., EPR (Pt/Ps), inHg, mb, and psia.


The tester also includes internal pumps that can produce a pressure and vacuum suitable for simulating


55K ft., 650 knots, and 6000 ft./min. conditions in wide body aircraft.
