PRODUCT OVERVIEW
RPM4-AD is a stand-alone, microprocessor driven, reference pressure monitor intended to precisely
measure gas pressure in the range of air data instruments.
performance and extensive features combined with maximum versatility and ease of use. It is particularly
well suited as a reference air data measurement device used to validate or calibrate air data test sets.
RPM4-AD uses two quartz reference pressure transducer (Q-RPT) modules and a barometer to measure
pressure. There are two configurations. RPM4 A160Ka/A160Ka covers the altitude and airspeed range
typically appropriate for rotary winged aircraft. RPM4 A350Ka/A160Ka covers the range of altitude and
airspeed typically appropriate for fixed wing aircraft.
RPM4-AD can be controlled locally by the operator using its front panel display and keypad or remotely
by a computer using ASCII character command strings transmitted over its standard RS232 or
IEEE-488.2 interface.
RPM4-AD is a specialized air data version of the RPM4 Reference Pressure Monitor.
Reference Pressure Monitor is available in a very wide variety of other configurations covering pressure
ranges from as low as - 3 to 3 kPa (0.4 psi) to as high as 280 MPa (40 000 psi) in absolute, gauge,
compound gauge and differential measurement modes.
