GP1 Sensr Programmable Accelerometer

The Sensr GP1 Programmable Accelerometer is a 3-axis motion recording instrument that allows the user to monitor, record and evaluate: motions, impacts, shocks, drops, orientation and temperature.

The GP1 incorporates a programmable 3-axis MEMS accelerometer. The user can select which range is appropriate for their application. The four acceleration ranges are: ± 2.5g, ± 3.3g, ± 6.7g and ± 10g. It is recommended that the user select the lowest range reasonable for their application as this will optimize data. Choosing an acceleration range does not limit the survivability of the accelerometer; the accelerometer is shock rated for more than 1000 gs.

When the GP1 collects data in the Data Recorder Mode it organizes sampled data into user-specified reporting intervals. A reporting interval is defined by a time segment the user defines; a time segment can be between 1 second and 120 seconds. The reporting interval does not influence the way the GP1 collects data, it only specifies the time resolution for reporting the data. For example, if the GP1 is set to report X+ axis max values with the specification of a 1 second reporting interval, the unit will sample at 100 samples per second and report the single highest sample within a given 1 second period. If the device’s reporting interval were reset to 60 seconds the GP1 would still sample at 100 samples per second but report the highest sample that occurred within the 60 second period. Choosing a shorter reporting interval will result in more data records for a given monitoring period. Selecting an appropriate reporting interval is a balance between data resolution, record length and storage capacity. Once a reporting interval is specified the software will display the number of days and hours the unit will store data. In general 60 second epochs is a good reporting interval for most applications—it facilitates reasonable data resolution and an extended monitoring period. ote: The GP1 reports all records in UTC time.

The GP1 can also be programmed to collect data in the Event Recorder Mode. This mode records each sample (3 axis—100 samples per second) into sequenced data records. Once the Event Recorder Mode is enabled the user can specify when the mode triggers and how long the mode records data. This mode can be used in conjunction with Data Recorder Mode.

The GP1 can be configured to be a real-time data capture device—this mode lets the user see the real-time acceleration influences as they are occur ring. For this function the unit needs to be connected to the user’s PC via the USB cable. No other modes can be used while Real-Time mode is enabled. Once enabled, the user can control when the system records/displays data. Recording control can be done on the PC or at the instrument. USB extenders can be used with this mode to increase the cable length if required.

The GP1 has an LED indicator that can be used to quickly determine the status of the unit. Depending upon the unit’s status, the LED will flash green, yellow or red. Each flash color and flash frequency has a specific meaning depending up on which mode is enabled.

The GP1 features a top mounted "Start" button. This button is used to control data recording as well as inserting notice inputs into the data record.
