User Manual 3320 Data Sheet 3320 User Manual G-Logger Software (Zip File) The G-LOGGERTM system was originally designed as a vibration monitor for NASA and the Space Shuttle Program. It provides portable, lightweight, and easy to use acceleration and temperature acquisition for a variety of applications. It is self-contained, sealed from the weather and can operate unattended for 7 to 21 days on two D-cell alkaline batteries, depending upon the sample rate and mission type selected. As a shipping recorder, the G-LOGGERTM can be used to provide time and date stamped evidence of physical mishandling and temperature fluctuations of cargo in transit. It can also be used to collect vibration and mechanical shock from operating equipment. Its compact size is ideal for use in experimental applications, crash testing, or to provide data for complex motion analysis. Up to three axes can be activated for acquiring, storing and analyzing AC/DC acceleration, AC velocity, shock and vibration.  The G-LOGGERTM is easily programmed through a serial link to your PC or notebook computer running Windows 95/98/NT4.0/2000/XP and can be set to record continuously, at set intervals, or in a variety of event triggered scenarios. Once programmed, the unit can be disconnected and securely bolted in place to provide hands free, unattended, data acquisition for the length of the desired mission. The availability of an external power source (5-18 V DC) extends mission life indefinitely within the memory restrictions of the desired program. The G-LOGGERTM can store up to four million samples of acceleration and temperature data in its non-volatile flash memory. Efficient use of this memory is made by preprocessing the data to include only the information of interest before being stored. The unit can store sampled, peak or RMS acceleration or velocity at a rate of from 1 to 4000 samples per second. It can also be set to only acquire acceleration data when user adjustable acceleration levels are detected. Upon completion of the mission, the data is downloaded via the serial connection to your PC or notebook for display and analysis. Both models (3310 and 3320) come complete with an RS-232 interface cable and the G-LOGGERTM Software program is meant to be used in conjunction with the optional EasyPlot data graphing and plotting program. We recommend this software option because of its low cost and our G-LOGGERTM Software Program. No data acquisition card is needed because all communication is handled via the RS-232 COM port on your PC. The G-LOGGERTM Software program contains a “PLOT” button, which provides a direct call to EasyPlot with automatic formatting and scaling of your plot. For user's who plan to use the "Peak Events" mission type, the G-Logger software has an "event preview" mode that only works with EasyPlot. In addition, EasyPlot has general math, FFT and integration functions for post collection analysis of your data. Visit www.spiralsoftware.com for more information on EasyPlot. Should you already own or choose to provide your own plotting software, the G-LOGGERTM Software Program can be set to output the data in an ASCII comma delimited format which is readable by most data graphing software packages. The original model 3310 is a self-contained unit, which includes an internal 3-axis accelerometer module and a temperature sensor. Its weather tight 3.5 x 4.5 x 2.2 inch case is constructed of die cast aluminum and weighs 29 oz including 2 D-cell batteries. It can be bolted down via two #8 screws without compromising the weather seal. The model 3320 is built around the same weather tight case as the 3310 and has the same internal temperature sensor, electronics and program interface. The internal 3-axis accelerometer module however, is replaced with a connector, which is used to attach a variety of external accelerometer combinations. The 3320 is designed to be used with either one model 2420 triaxial accelerometer or up to 3 model 2010 single axis accelerometers. These small and lightweight acceleration modules can be used in applications where the physical surface(s) to be monitored would not support the size and weight of the self-contained model 3310. If model 2010 accelerometers are to be used, a model 3901 (tri-Y) Adapter Cable is also required which allows the individual 2010’s to be separated by up to 6’ from each other. The 3320 also includes a 10’ extension cable which is used to connect either a model 2420 triax or a model 3901/2210 single axis combination. Please see the model 3310 or 3320 Data Sheets for Operational Specifications, or contact with specific questions. |
