ADC-2522 Air Data Calibrator

Product Details

The ADC-2522 is built on the ADC-2550 series platform. It is designed for rackmount use and features a large 10.4″ display with resistive touchscreen. The calibrator has the ability to emulate the Sperry / Honeywell ADT-222B IEEE-488-1975 communications. This allows the calibrator to be a plug and play replacement for the aging Honeywell ADT-222B Air Data Test System and similar test sets, without the expense in having to modify existing communication protocols or software.

  • P/N: ADC-2522 | NSN: 4920-01-105-0016
  • Fully qualified replacement for ADT-222B Model 4047505-422 and 4047505-421
  • High Precision Air Data Test Calibrator (ADT-C) used by PMEL
  • Designed for ATE – features plug and play for Honeywell/Sperry emulation
  • Interfaces: RS-232, IEEE-488.2, Honeywell IEEE-488-1975


adc-2522-1The ADC-2522 (NSN: 4920-01-105-001) features a 10.4-inch LED backlit LCD display with an integrated touchscreen. The calibrator features an uncluttered and intuitive software interface. The calibrator uses two (2) high precision, non-density sensitive transducers, which provide unmatched accuracy and performance. Corrections are done through software, requiring no mechanical adjustments, and are capable of holding their accuracy for a period of at least one (1) year.

Simple Intuitive Interface

The ADC-2522 software provides a familiar and intuitive graphical user interface for any operator. The calibrator measures and record readings and displays the data in table format or graphically in real-time. Each session is automatically saved and stored on the calibrator. In addition, the calibrator can be operated remotely through the RS-232 (serial) located on the rear panel. The ADC-2522 features a standard IEEE-488.2 interface. The system also features a legacy Honeywell ADT-222B IEEE-488-1975 emulator and circular connector. This interface allows the ADC-2522 to become a plug and play solution for the aging ADT-222B (NSN: 4920-01-105-0016 and P/N: 4047505-422 and P/N: 4047505-421). The ADC-2522 calibrator has been tested and qualified for use by USAF PMEL organizations worldwide to replace the ADT-222B. Additionally, the ADC-2522 operating system platform is designed for expandability through software updates, allowing it to be adaptable to future test requirements.

adc-2522-rearSafety and Protection

The ADC-2522 incorporates several hardware and software measures to protect the air data calibrator and the device under test (DUT). The ADC-2522 features input pressure regulation, over-range, over-limit and over-pressurization protection. 5 micron micro-porous filters and screening prevent debris from entering the system. The calibrator is also equipped with pressure relief valves to protect the pneumatic system components and the DUT from damage caused by excessive pressures. The front panel manual vent valve is used to accelerate venting of the Ps manifold to ambient pressure. ADC-2522 software is designed with limit exceedances and settings, providing additional safety to the DUT. Software is designed to prompt and warn the user when pressure ranges exceed the limitations of the test set. Test Profiles can be set up for different test applications so that users are not required to manually enter set points and tolerance each time.
