Recent updates allow users to select and compare multiple data logs.
Up to four recorded data sets can be displayed together on an overlaid graph.
This is particularly useful for comparing:
- Repeated pressure tests
- Different DUTs
- Different calibration periods
- Pressure stability tests
- Hydrostatic test results
The cloud-based environment therefore expands the XP3i beyond simple pressure indication.
Optional DataLoggerXP
The AMETEK Crystal XP3i can be upgraded with:
DataLoggerXP.
This option provides extensive internal pressure recording capability.
With DataLoggerXP, the XP3i can store:
more than 200 million data points.
This represents a major increase in logging capacity compared with the previous XP2i generation.
More Than 200 Million Data Points
The enormous data storage capacity allows the XP3i to perform extended pressure monitoring without continuously transferring data to a computer.
Recorded runs can remain stored in the gauge and subsequently be downloaded.
After the data have been transferred and deleted from the gauge, the storage capacity is available for new measurements.
This is especially useful for field applications where continuous computer connectivity is not practical.
More Than One Year of Continuous Recording
With the appropriate DataLoggerXP configuration, AMETEK specifies:
more than one year of continuous recording time.
An Ultra Low Power mode helps extend battery life during long-duration pressure monitoring.
This makes the XP3i suitable for applications such as:

- Leak testing
- Hydrostatic testing
- Pressure stability testing
- Process monitoring
Logging from the Gauge or Smartphone
Data logging runs can be started and stopped directly from:
the XP3i
or, using Bluetooth:
the CrystalConnect mobile application.
This provides additional flexibility when the pressure gauge is installed in a remote or difficult-to-access location.
Fast Data Logging
The XP3i offers significantly faster data logging than the previous XP2i generation.
With the appropriate configuration, logging rates can reach:
5 measurements per second.
This is useful when pressure changes occur quickly and a slow logging interval could miss important events.
Pressure Safety Valve Mode
The AMETEK Crystal XP3i includes a dedicated:
PSV – Pressure Safety Valve mode.
This function is designed for pressure relief and safety valve testing.
During a test, the XP3i monitors the rising pressure.
When the valve opens and pressure drops, the gauge captures the relevant peak pressure.
This simplifies determination of the valve opening or pop pressure.
Hydrostatic Testing
The combination of high pressure capability, rugged construction and optional data logging makes the XP3i particularly suitable for:
hydrostatic pressure testing.
A pressure system can be pressurized to the required test value and monitored over a defined period.
With DataLoggerXP, pressure measurements can be automatically recorded throughout the test.
The recorded results can subsequently be transferred to CrystalControlWeb for analysis and reporting.
Leak and Pressure Decay Testing
The XP3i can also be used for:
leak testing and pressure decay testing.
Pressure can be monitored over time to determine whether a system maintains the required test pressure.
Data logging provides a digital record of the complete test sequence.
This can provide substantially better documentation than manually recording individual pressure values.
