Dps350 Manual
The Barfield DPS-350 avionics test equipment is a bench tester which is based on a microprocessor utilizing the newest in transducer technology. The DPS350 operates exactly the same to Barfield's 1811 series test sets however the transducer technology used is nearly invulnerable to the costly repairs normally felt by analog instruments. Its software which has a programmable defense limit characteristic has been incorporated into the DPS350 to insulate the aircraft instruments from damage resulting from negative airspeed and over pressurization situation. Defense limitation is provided by computer actuated solenoid valves that defend aircraft altitude, airspeed, rate of climb/decent and mach instruments.

The high accuracy and reliability demonstrated by the transducers succeed the DPS350 for use on aircraft being certified for Reduced Vertical Separation Minimum (RVSM) method and increase the calibration interval from thirty days to annually. The simple menu driven digital display measures and displays Altitude, Vertical Speed, Airspeed, EPR and other values in many different units of measure, including: Ft, M, Kts, Km/hr, Mach, Ft/min, M/min, EPR (Pt/Ps), inHg, mb, and psia.
DPS 350 also features internal pumps which could produce a pressure and vacuum suitable for simulating 55K Ft, 650 Knots, and 6000 Ft/min circumstances in large body aircraft.
Includes the. The new DPS450 completes an entire line of Barfield Digital Pitot-Static/Air Data testers. Designed to minimize aircraft downtime, the DPS450 is the newest and one of the lowest cost fully automated Air Data Testers meeting the high accuracy demands of Reduced Vertical Separation Minimum (RVSM) specifications on the market. All functions of the tester are fully automatic and require no manual sequencing of valves or regulators. The DPS450 has fully automatic control by means of the menu-driven high contrast electroluminescent display and tactile membrane keypad. The automated controller automatically generates and continuously maintains the input altitude, airspeed or VSI values. The DPS450 precisely maintains the input value (Ps, PT, Airspeed, Alt, etc.) overcoming any pressure values caused by a leaky system.
A precision sensor on the static channel provides high accuracy altitude measurement and simulation. This high accuracy and stability (see Air Data Specifications for details) qualifies the DPS450 for certifying aircraft for RVSM operation and increases the calibration interval from 30 days to once every year.
Dps 350 User Manual
The sophisticated yet user friendly display is fully programmable for a range of test requirements. It can be configured, with limits and referred units of measurement, for individual aircraft types. The level of information displayed can be determined by the operator to suit the particular task at hand. In addition to the standard pitot-static functions of the DPS450, there are many additional advanced features that include: automatic go-to-ground, leak test mode and device under test protection amongst others. This enables the operator to undertake flightline testing accurately and efficiently, without compromising safety standards.
