Barfield DPS450 Digital Pitot-Static (Air Data) Test Set
The Barfield DPS450 is a fully automatic air data test set for testing and calibrating aircraft pitot-static systems and instruments. Barfield positioned it as the newest and one of the lowest cost fully automated testers that still meets the high accuracy demands of Reduced Vertical Separation Minimum (RVSM) certification. It completed Barfield’s line of digital pitot-static testers designed to minimize aircraft downtime.
Key Features
- Fully automatic control: no manual sequencing of valves or regulators and the controller generates and continuously maintains the altitude airspeed or vertical speed value you set
- Compensates for leaks: holds the input value (Ps, Pt, airspeed, altitude, and so on) even against a leaky system
- Menu-driven interface: a high contrast electroluminescent display with a tactile membrane keypad programmable for a range of test requirements
- RVSM-qualified accuracy: a precision static channel sensor delivers altitude accuracy of ±3 ft at -1,800 ft, ±4 ft at 10,000 ft, ±6 ft at 20,000 ft, ±7 ft at 30,000 ft, ±12 ft at 40,000 ft, ±19 ft at 50,000 ft, and ±29 ft at 60,000 ft
- Airspeed accuracy: from ±2.0 knots at 23 knots, improving to ±0.5 knots at 50 and 100 knots, ±0.3 at 200, ±0.07 at 500, and ±0.1 knots at 650 knots
- Strong repeatability: altitude repeatability as fine as ±1.4 ft at low altitudes and about ±15.4 ft at 60,000 ft
- Longer calibration interval: its high accuracy and stability extend calibration from every 30 days to once a year
- Static channel accuracy: meets 0.0030 inHg
- Protective and test functions: automatic go to ground a leak test mode and device under test protection to safeguard aircraft instruments
- Alternate designation: also referenced as the ADTS-505 in distributor listings
Typical Applications
- Pitot-static system leak and accuracy checks
- RVSM and other certification testing
- Calibration of altimeters, airspeed indicators, and vertical speed indicators
- Flightline and hangar maintenance
- Repair station and avionics shop use
Why Choose It
The Barfield DPS450 gives maintenance teams the automation and RVSM grade accuracy of a high end air data tester at a lower cost with a longer calibration interval that reduces ongoing costs and downtime.
