Digital Pitot Static Test Set

The Barfield DPS350 Air Data Tester is a microprocessorbased unit using the latest in transducer technology. The DPS350 operates similar to Barfield’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.
