PDF spec sheet

The PC6-AV Pressure Calibrator is designed as a 2bar/30psi absolute unit (+60 in Hg) that can be used as a barometer. It calibrates air speed indicators, altimeters and performs leak tests on the pitot system. It can be
used with all types of aircraft, and represents the most recent development in aerospace calibration.

The system is supplied with a TP1 scissor action pump or the LTP1 low-pressure pump with fine control. Both pumps incorporate adjustable over pressure protection, to avoid over pressuring units under test.

The clear LCD display has a back light for easy use in poor light situations and is small and portable. The PC6-AV Pressure Calibrator has an accuracy (FS) better than 0.025% and resolution (FS) better than 0.01%.

Pressure units can be recorded on the PC6-AV in mbar, inHg, knots, kPA, psi, atm, in H2O, mH2O, mmH2O, bar, mmHg, unit1, unit2 with altitudes measured in feet or meters with a range of -3,000 ft. to 105,000 ft. Non-corrosive gases are the preferred pressure media (contact Cyronix for other media), and the pressure connections are 1/4” BSP, or 1/4” NPT male (8mm O/D hose connector). Temperature effects are 0.001% of reading/ºC between 10-40ºC, and data capacity is 175 records into a maximum of 20 files, 8K memory with an option to increase that capacity by an additional 8K.

RS232 communication is included in the design and the optional SI-CAL software will present downloaded data in various graphic forms such as gauges or a scrolling bar and remotely control the PC6-AV Pressure Calibrator via the RS232 cable linked to a PC. Data storage is compatible with most analysis, database and word processing programs.
