PRODUCT OVERVIEW
RPM4/HPMS A70M/A20M-AF is the combination of an RPM4 A70M/A20M-AF reference pressure
monitor and an HPMS High Pressure Mounting System.
RPM4 A70M/A20M-AF is a stand-alone, microprocessor driven, reference pressure monitor intended to
accurately measure gas pressure in a variety of pressure calibration, measurement and testing
applications. It has been designed to provide very high performance and extensive features combined
with maximum versatility, ease of use and durability. RPM4 A70M/A20M-AF covers the range from 0 to
10 000 psi gauge and atmosphere to 10 000 psi absolute using two high accuracy quartz reference
pressure transducers (Q-RPTs) and an on-board barometer to measure pressure.
RPM4 A70M/A20M-AF is controlled locally by the operator using its front panel display, keypad and foot
pedal or remotely by a computer using ASCII character command strings over its RS-232 and IEEE-488
interfaces.
RPM4 A70M/A20M-AF uses an AutoRange feature to automatically select the most appropriate Q-RPT
and to optimize the RPM4 setup to cover the range.
The HPMS mounts the RPM4 at a convenient viewing angle and contains the hardware to isolate the
RPM4’s low pressure Q-RPT (A20M (3 000 psi)) when the high pressure Q-RPT (A70M (10 000 psi) ) is
in use.
RPM4/HPMS A70M/A20M-AF is typically delivered as part of a PGC-10000-AF Pneumatic Gauge
Calibrator. The PGC-10000-AF system includes a GPC1-10000-AF pneumatic pressure controller and a
GB-152-AF gas booster that have their own Operation and Maintenance Manuals.
