Pressure Recording with an XP2i in Ultra Low Power Mode
Recording of pressure data, or data logging, is increasingly becoming a requirement of
many companies. Whether you are testing for long term trends, looking for anomalies, or
documenting required tests, having an accurate and reliable pressure recorder is essential.
While pressure recorders can differ in many ways, including accuracy, features, ease of use,
and recording space, one thing that all field recorders have in common is batteries. If you
have a long-term test, finding an instrument that will collect all the information you need
without running out of batteries can be difficult.
Long-Term Recording of Pressure Data
If a long-term, in the field, recording solution is what you are looking for, look no further than the XP2i. The XP2i,
already one of the world’s most popular test gauges, has an Ultra-Low Power (ULP) recording mode that is the
solution to long-term recording problems.
The ULP mode of the XP2i Datalogger extends the battery life by putting the gauge into a reduced power
mode in between collection of readings. Whereas a normal datalogger is constantly powering the gauge
throughout its recording, the ULP mode shuts down the gauge in between readings, except for the internal
clock and the low power display. This battery saving technique dramatically extends the battery life.
So Just How Far Will One Set of Batteries Last With the XP2i in ULP Mode
With an extended logging interval of one reading every 17 minutes, the XP2i test gauge with the optional
DataLoggerXP upgrade will last over one year on just four AA batteries. If you only need one month of data, the
logging interval can be increased to one reading every 2 minutes.
