Barfield DPS400

Barfield DPS400

The DPS400 is a microprocessor based unit using the
latest in transducer technology. These transducers
combined with manually controlled ultra sensitive
differential regulators enable a technician to precisely
control the altitude and airspeed without the need for
correction cards. These true differential regulators
enable a technician to independently control the
airspeed and altitude and remove the need for a
crossbleed valve. The accuracy and a stability (see
pages 11-12 Air Data Specifications for details) qualifies
the DPS400 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.

Features:

• Transducer Technology providing the highest accuracy and best long-term stability available for line maintenance equipment
• True differential regulators used for independent control of airspeed and altitude
• Menu-driven operator interface providing protection of instruments under test with programmable limits on the following parameters: Altitude (feet or Meters), Airspeed (Knots or Km/Hr), Rate of Climb (Ft/Min or M/Min), and Mach (mach)
• Leak testing mode displays leak rates in Ft/Min, Knots/Min and Metric equivalent units.
