Battery powered pressure data Logger for standalone pressure recording13th August 2007 Ad hoc applications for pressure testing new products or production machinery do not necessarily require an elaborate data acquisition system with many input channels permanently connected to a PC. If the test is to be carried out in a intrinsically safe area a simpler approach becomes even more desirable.Often a single channel pressure data logger which can be easily moved around is a much more convenient and cost effective alternative, especially if it is also battery powered and intrinsically safe for use in potentially explosive atmospheres. For improved performance when leak testing it is useful to also record temperature so that pressure variations caused by adiabatic effects rather than leaks can be identified and excluded from the results to determine the true leak rate. The LEO record pressure data logger is a battery powered compact instrument which can store up to 57,000 readings of pressure and temperature in its non-volatile memory. Pressure ranges from -1 to +1 bar up to 1000 bar gauge or absolute are covered by the LEO Record pressure data logger and unlike other data loggers it has a built-in LCD digital readout for displaying the real-time pressure level and the data logging running mode. The stored pressure and temperature readings are retrieved from the LEO Record pressure data logger via a USB or RS232 interface cable connected to a PC, Laptop or Pocket PC. All data logging parameters are configured using the Logger software which is supplied with the data communications kit. For pressure testing carried out in hazardous areas the LEO Record pressure data logger is available in an intrinsically safe version. The logging procedure is uploaded in the safe area via the USB or RS232 interface so that the LEO Record pressure data logger can then be transferred to the hazardous area to run the test powered by the internal battery. Once the pressure test is complete the LEO Record pressure data logger can then be returned to the safe area for downloading the test results. The LEO Record pressure data logger is powered by a SL-760 Lithium battery which lasts up to 5 years if 1 reading is recorded every 10 seconds or 2 years if 1 reading is recorded every second. The compact housing of the LEO record pressure data logger has an IP65 ingress protection rating allowing it to be used outdoors if necessary and there is an optional rubber boot protective cover to prevent damage if dropped.
