PPCH™

Hydraulic Pressure
Controller/Calibrator
High performance pressure
generation and control to200 MPa (30 000 psi)

PPCH™, is a pressure generator/controller/calibrator for liquid pressure operation from
1 to 200 MPa (150 to 30 000 psi). As with therest of the Fluke Calibration PPC family of pressure controllers, the emphasis is on high end
performance, minimizing measurement uncertainty and maintaining precise control over a
very wide pressure range—in a compact andrugged instrument.
New, individually characterized, quartz
reference pressure transducer (Q-RPT) modules
increase precision and reduce measurement
uncertainty. The AutoRange™ feature supports
infinite ranging, automatically optimizing all
aspects of operation for the exact range to be
explored and taking pressure controller rangeability to a new level.

Technical DataFeatures• Pressure “ready/not ready”
indicator with user adjustable criteria• Intelligent AutoZero™
function• 16 SI and US pressure units• Automatic fluid pressure
head correction• On-board, programmablecalibration sequences with
UUT tolerance testing• Remote [ENTER] footswitch
for hands free test execution• Valve drivers option forsystem design• Automated leak testingroutines• RS-232 and IEEE-488
communications• FLASH memory for simple
and free embedded software upgrades fromwww.flukecal.com

A unique pressure generation and control
system provides unlimited, on-demand pressure,very high control resolution and 10:1 pressure
control turndown. Four different control modes
are included for maximum versatility.
Open architecture allows reference pressure measurement to be internal to or remotefrom the controller. If desired, the reference canbe located at the test measurement point andindependently removed for recalibration.
With all of this, PPCH opens new doors in
automated high pressure hydraulic calibrationand test applications.

Quartz reference pressuretransducer (Q-RPT) modules

Open architecture

PPCH’s outstanding pressure measurement
specifications are made possible by the Fluke
Calibration exclusive quartz reference pressuretransducer (Q-RPT) modules.
Q-RPTs measure pressure by measuring thechange in the natural oscillating frequency ofa quartz crystal with pressure induced stress.
To be qualified for use in a Q-RPT module, eachtransducer is individually evaluated and characterized using automated primary pressure
standards. Only transducers exhibiting required
levels of linearity, repeatability and stability areselected. A proprietary compensation model,derived from more than 15 years experience
with thousands of quartz pressure transducers,
is applied to optimize the metrological characteristics needed in a transfer standard.
PPCH can be delivered with a low cost utility
sensor for applications in which the high precision and stability of a Q-RPT are not required.

Hi Q-RPT only, not available in Lo Q-RPT position.

A PPCH controller can be configured with up tofour Q-RPT modules. These can be internal orexternal to the PPCH controller. External Q-RPTs
are in Fluke Calibration RPM4™ Reference Pressure Monitors. The RPM4’s Q-RPTs then become
part of the PPCH system and are managed by
PPCH. External Q-RPTs must be disconnected orprotected by valves when PPCH is used at pressure greater than the external Q-RPT range.
Examples of possible PPCH system configurations include:• A PPCH with one or two built-in Q-RPTs toact as a stand alone, “one box” controller/calibrator package• A PPCH with no internal Q-RPTs and an
external Q-RPT to configure a system whosereference pressure measurement is remotefrom the controller. This configuration is ideal
when it is advantageous for the reference tobe removed from the system (e.g. for recalibration) while leaving the controller installedor to locate the reference measurement incloser proximity to the device or system undertest• A PPCH with no built-in Q-RPTs to act asa low cost automated pressure setting andcontrolling device (for example to automatepressure control in a PG7000 ™ piston gaugesystem)

Infinite ranging™ and autoRange™
There’s a lot more to covering a wide range oftest devices with a single pressure controller
than “% of reading” measurement uncertainty.
In addition to the necessary measurement
uncertainty, PPCH offers the full pressure controland feature adaptability that are needed for true
rangeability in test and calibration applications.
Infinite Ranging gives PPCH unprecedented
versatility in adapting to a wide variety ofdevices to be tested. With the easy to use
AutoRange function, a few simple key strokes
or a single remote command string at the startof a test adapts every feature of the controller tooptimize it for a specific range.

12Conﬁguring a PPCH model number

1. Determine maximum controlled pressure required. Select:PPCH-200M for 200 MPa (30 000 psi)
PPCH-100M for 100 MPa (15 000 psi)
PPCH-140M for 140 MPa (20 000 psi)
PPCH-70M for 70 MPa (10 000 psi)

2. Decide whether Q-RPTs will be internal (built-in to PPCH) and/or external (in remote RPM4).
3. If Q-RPTs are to be built-in to the PPCH, select one or two Q-RPTs from the Q-RPTs table on
page 3. Lo Q-RPT must be A70M or lower.

4. If Q-RPT(s) are to be external to the PPCH, conﬁgure an appropriate RPM4 using the RPM4brochure. Note that the maximum pressure of the PPCH deﬁnes the maximum pressure of the
PPCH system.
