RPM4

Reference Pressure

Monitor

Technical Data

Premium performance, unmatched features, compact and rugged

RPM4 is much more than a traditional pressure indicator

State of the art performance from very low pressure to 280 MPa (40 000 psi)… advanced on-board features…compact and rugged…full local and remote communications…RPM4 is the perfect solution in a wide variety of high end pressure calibration, testing and measurement applications.

Infinite Ranging

™

and

AutoRange

™

Infinite Ranging gives RPM4 unprecedented versatility in adapting to the specific range of operation. With the easy to use AutoRange function, a few simple key strokes or a single remote command string at the start of a test adapt every feature of the pressure monitor to optimize it for the range to be covered. Just enter the maximum pressure and the measurement mode.

AutoRange then:

• Selects and activates the most appropriate Q-RPT to cover the specified range and measurement mode.

• Sets the pressure unit of measure.

• Activates absolute, gauge or compound gauge measurement.

• Adjusts display resolution to the appropriate level for the range.

• Adjusts overpressure alarms to the actual range of operation.

• Reduces measurement uncertainty proportionally to the selected range

(premium class Q-RPTs only).

Note: The use of RPM4’s Infinite Ranging and AutoRange feature is recommended to optimize operation for a specific range but is not required to obtain “% of reading” measurement specifications.

SDS

™

Q-RPT Self Defense System

™

All Q-RPT modules up to 7 MPa (1 000 psi) include the Fluke Calibration unique Self

Defense System (SDS). SDS valves automatically isolate and vent the module’s Q-RPT when it is not in use or an overpressure is about to occur. With SDS, any Q-RPT module can be left connected to pressure up to 10

MPa (1 500 psi) without needing to isolate or disconnect it.

Advanced on-board functions

RPM4 provides a variety of advanced onboard pressure data functions including:

• Special data such as pressure average over time, rate of change, hi/lo, freeze, deviation from set point

• Differential mode directly measures the difference between two Q-RPTs including taring at the line pressure

• Parallel measurement uses two Q-RPTs redundantly as one

• Leak check measures average pressure rate of change over a user set time period

• AutoTest automates calibration routines with tolerance testing and data logging

2 Fluke Corporation RPM4™ Pressure Reference Monitor

Quartz reference pressure transducer (Q-RPT) modules

RPM4’s outstanding pressure measurement specifications are made possible by DHI's exclusive quartz reference pressure transducer (Q-RPT) modules.

Q-RPTs measure pressure by measuring the change in the natural oscillating frequency of a quartz crystal with pressure induced stress. To be qualified for use in a Q-RPT module, each transducer is individually evaluated and characterized using primary pressure standards. Only transducers exhibiting required levels of linearity, repeatability and stability are selected. 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. Standard and premium class

Q-RPT modules are available to best fit your performance and budgetary requirements.

A unique dynamic compensation for atmospheric pressure system uses an independent on-board barometer to provide seamless switching between absolute, gauge and compound gauge modes at any time. The barometer is used only to measure the small variations in atmospheric pressure that occur during gauge mode operation so its absolute error and drift over time do not contribute to measurement uncertainty.

Q-RPT modules offer the advantages of:

• % of reading measurement uncertainty with AutoRange span turndown available

• Negligible warm up time

• No gas species dependence

• Quartz element isolated from test medium

• Low sensitivity to orientation

To UUT

Compatible with PPC3 automated pressure controller

RPM4 can be used as an external reference pressure measurement device for a DHI PPC3, fully automated, pressure controller/calibrator. One or two RPM4s can be “daisy chained” to PPC3 by 9 pin RS-232 cable(s). The RPM4's

Q-RPTs become part of the PPC3 system and are managed by PPC3 transparently to the user. There is only one test connection for the PPC3 system‘s full range of operation.

See the PPC3 product brochure for additional information.

3 Maximum deviation of the Q-RPT indication from the true value of applied pressure including precision, predicted one year stability, temperature effect and calibration uncertainty, combined and expanded (k=2) following the ISO “Guide to the

Expression of Uncertainty in Measurement.”

4 % of reading value times measured pressure from 100 % to 30 % of Q-RPT span. Under 30

% of Q-RPT span, % of reading value times 30

% of Q-RPT span. For example, if the Q-RPT is a

Standard A160K, the Measurement Uncertainty in pressure is 0.010 % times the measured pressure to 48 kPa (160 kPa span x 30 %) and 0.0048 kPa

(160 kPa span x 30 % x 0.01 %) under 48 kPa.

5 % of reading value times measured pressure from

100 to 30 % of AutoRanged span. Under 30 % of

AutoRanged span, % of reading value times 30 % of AutoRanged span. If AutoRanged span is less then 30 % of maximum Q-RPT span, % of reading values times measured pressure, or % of reading times 9 % of Q-RPT span, whichever is greater.

For example, if the Q-RPT is a Premium A160K and

AutoRanged span is 160 kPa, the Measurement

Uncertainty in pressure is measured pressure x

0.008 % to 48 kPa (160 kPa AutoRanged span x

30 %) and 0.0038 kPa (160 kPa span x 30 % x

0.008 %) under 48 kPa. If the AutoRanged span is

100 kPa (greater than 30 % of 160 kPa maximum

Q-RPT span), the Measurement Uncertainty in pressure is measured pressure x 0.008 % to

30 kPa (100 kPa AutoRanged span x 30 %) and

0.0025 kPa (100 kPa span x 30 % x 0.008 %) under 30 kPa. If the AutoRanged span is

30 kPa (less than 30 % of the 160 kPa maximum

Q-RPT span), the Measurement Uncertainty in pressure is measured pressure x 0.008 % to

14.4 kPa (160 kPa maximum Q-RPT span x 9 %) and 0.0012 kPa (160 kPa maximum Q-RPT span x

9 % x 0.008 %) under 14.4 kPa.
