Give Me More Information
The SnapShock Plus (SSP) accelerometer, serves as an impact indicator and transportation data recorder. The device is a compact, battery powered acceleration event recorders that records peak acceleration including impact, vibration and shock. The new generation devices offer several improved capabilities over the standard Snap Shock accelerometer model. In addition to measuring peak-g shock levels with a built-in accelerometer sensor, the SSP also measures and records shock duration and velocity change (measure of shock energy) for all events which exceed user defined thresholds. In addition the SSP is now available in tri-axial version referred to as the SnapShock Plus/3D (SSP/3D)acceleration data logger / impact & transportation data recorder.
Each instrument measures and records the peak acceleration levels to which it is exposed along with shock duration and velocity change, and the exact date and time of occurrence. The user may specify recording thresholds in g-level, as well as velocity change, so that only those events which exceed g-level and velocity change thresholds of interest are actually recorded into permanent memory. The SSP acceleration data recorder series utilize a low power design, enabling operation for weeks at a time while running on a single 9-volt battery.
Easy Calibration Checks
Since the SnapShock Plus accelerometer recorder offers DC response capability, the recorder's calibration can easily be checked against Earth gravity, without requiring any additional test equipment. A simple 90 degree rotation produces a traceable 1g change in acceleration level, and a 180 degree rotation produces a 2g change. This is a simple and easy technique for introducing a calibration reference input into the recorder prior to sending the unit out for field recording.
The programmable parameters for the SnapShock Plus acceleration recorder include the g-trigger levels-(x, y, z), velocity trigger thresholds (x, y, z), 3dB cutoff frequency for signal filtering (Hz), and pre-set start and stop dates/times. A separate recording mode switch is also available for allowing the user to simply select either Shock Event or Drop Height mode, for which the triggering parameters are automatically selected for optimal analysis results. The SnapShock-Plus can also concurrently log environment temperature at user defined time intervals.
Interfacing Other Transducers
The SnapShock Plus acceleration recorder can be factory-modified to support data recording from transducers other than accelerometers. Examples of other measurements possible include pressure, strain, load, temperature, and humidity. Contact IST for specific information in these areas.
DynaMax for Windows 98/NT/Me/2000/XP/W7
Data from the SnapShock Plus acceleration recorder series recorders may be uploaded and analyzed in a variety of formats using IST's DynaMax for Windows software package operating under most Windows Operating Systems.
DynaMax is the same program used for our more sophisticated waveform recorders, so it provides all the views and sorting abilities you've come to expect with easy snapshots to Word or Excel and quick exporting. In designing DynaMax the customer's ease-of-use has been the #1 priority.
You'll find the familiar scroll bars, dialog boxes, buttons file navigation features, etc., all there just as you would expect in a full featured Windows application.
Here are sample screen shoots of DynaMax:
The SnapShock Plus acceleration recorder utilizes an internal piezo-resistive (PR) accelerometer sensing element. This solid state sensing element offers excellent low frequency response capability, enabling accurate measurement of low frequency phenomenon such as rail car impact, freight handling impacts, packaging drop and impacts, aircraft turbulence and landing impacts, etc.
Several standard measurement ranges are available: + 10g, +/-50g, + 100g and +/-200g. . Other ranges may be available on special order, from +/-2g to +/-2,000g.
The SnapShock Plus acceleration recorder is supplied with an integral single-axis or triaxial accelerometer, microprocessor controlled data acquisition, user-selectable filtering and signal conditioning, solid-state non-volatile data memory, and an external activation push-button. For setup and data recovery, the SSP is connected with a host PC running IST's DynaMax user interface software running under Windows, via wireless infrared and/or USB communications.
During operation the SnapShock Plus acceleration data logger / impact indicator & transportation data recorder can measure and record up to 1475 time-tagged, peak acceleration levels. With the optional extended data memory this can be increased to 5900 readings.
The storage medium on the SnapShock is non-volatile, solid state EEPROM, providing maximum data security even if the battery becomes completely discharged. The SSP may be activated for recording under either computer control or by the manual push button control. The unit may be cycled repeatedly in and out of recording mode during a single test session without requiring a host PC. Once activated the SnapShock Plus triggers and records only those acceleration events which exceed the trigger criteria.
The SnapShock Plus acceleration recorder is designed for documenting dynamic environments such as moving vehicles, trains, planes, packaged products and containers, ships, etc. The device is also useful in characterizing environments such as production and assembly lines of delicate electronics, IC fabrication, communications and computer components, as well as vibration sensitive active pharmaceuticals. The instrument can also be used for very low g (floor vibration) as well as high-g applications with special order ranged sensors.
