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
