IST Instrumented Sensor Technology

The EDR-3C is a portable impact, shock and vibration full waveform recorder and has a built-in triaxial accelerometer that’s designed to measure shock, vibration, temperature and (as an option) humidity, pressure, or resistance-bridge devices. The programmable unit tags all acceleration events with a time and date to provide a time history of the dynamic environment experienced during a recording session. The EDR-3C series instruments offer a time-tested reputation for proven performance and reliability with hundreds of successful installations since the mid 90s. The EDR-3C series operates similarly and differs primarily in programmability features, on-board memory and channel capacities. Each recorder is powered by a specially designed C-Cell battery pack (9 Volt optional.) The EDR-3C recorder is used in conjunction with IST’s DynaMax Suite Software programs and downloads the EDR-3C's memory to a PC using USB or high speed serial commmunications. Together, the EDR-3C and the DynaMax software program provide a powerful tool for accurately recording and analyzing dynamic environments.

Standard range +-300g Threshold triggered 2, 500 event memory Wireless data interface Electronics epoxy encanpsulated Available for rental or purchase Applications Athletic helmet testing Crash testing Drop testing Athletic event measurement Military helmet testing Space constrained shock testing The HIRTS-1 is a compact, self-contained recording device which measures and records shock and impact to helmets or other space constrained fixtures. The device is planted or installed to an inside surface of the helmet. The device contains three accelerometer sensors which accurately measure the accelerations (forces) during helmet impacts, in 3-directions. Therefore the device can measure and record impacts from any direction, and at any time. During an impact event the device measures and records the peak, or maximum, acceleration (force) of the event, in each of three axes (x, y, and z) along with the exact date and time of occurrence. In addition, the device measures and records the “change in velocity” (proportional to energy) associated with the impact acceleration event in each of three axes (x, y, and z). The HIRTS device can continue to take these measurements for multiple times (up to thousands) and for up to several days of self contained operation. After a recording session (controlled test, practice or game) is complete the device is connected to a computer via wireless infrared in order to retrieve the recorded data. The data is displayed in a spreadsheet-like table listing all recorded events, by number, date, time, peak-g force values, and delta-V energy values. This data can then be used to assess the severity of helmet impacts sustained by the athlete, and potentially used to determine concussion severity for impacts that are unusually high in amplitude and energy. The device can also serve as a tool to identify impacts that may be of concussion severity but that may not have been reported as such by the athlete himself to his coaching staff.

The PANTHER Model EDR -4 series shock & vibration data loggers, monitors and recorders are self-contained, user-programmable acceleration sensorrecorders. The compact, 5lb. Package is designed for remote, stand-alone shock and vibration measurement and recording over extended time periods ranging from several hours to several weeks. The EDR-4 shock & vibration data monitor, logger and recorder is a precision field measurement instrument offering major improvements in recording speed, onboard data storage, dynamic range, data management, and programmability features. The PANTHER shock & vibration data monitor, logger and recorder is programmed for test using a standard PC serial or parallel port, along with IST's DynaMax DM-1 software module. After Field recording data is transferred back to the host computer for processing and analysis. Each PANTHER shock & vibration data monitor, logger and recorder is powered by a specially designed, user serviceable D-cell battery pack. The PANTHER's recording function is controlled by a custom designed recording and data management engine. The design is highly optimized for minimal power consumption while running at high, multi-channel digitization rates, and extremely large data memory storage capacities. During active recording acceleration signals are digitized to 12 bit resolution and stored in digital memory onboard the unit. The PANTHER shock & vibration data monitor, logger and recorder offers from 6 MB up to 108 MB of onboard data memory for wave-form recording. For airborne applications the PANTHER shock & vibration data monitor, logger and recorder is capable of recording upwards of 90 minutes of data while providing a 2kHz analysis bandwidth. For lower frequency ground transportation applications the unit is capable of recording continuously for several days before filing its memory. Data management in the PANTHER shock & vibration data monitor, logger and recorder allows the unit to measure and record up to 32, 000 individual 3-channel waveform sets comprising transient shock events or continuous vibration. The length of each event is user configurable enabling the unit to be tailored to particular measurement tasks. Acceleration recording can be configured for measurement from either the three internal(triaxial) accelerometer channels, or from up to three optional external accelerometer channel inputs. The PANTHER EDR-4M6 shock & vibration data monitor, logger and recorder model offers recording capability from six input channels simultaneously. The PANTHER shock & vibration data monitor, logger and recorder also measures and records environment temperature using sensors built into the instrument. Optional external temperature and relative humidity sensors are also available.

The MSR-3C is a self-contained low cost portable accelerometer data logger unit with a multi-channel, digital acceleration waveform recording system. Our portable acceleration data logger system is battery powered, designed for field applications requiring multi-channel, extended time, unattended acceleration monitoring and recording. The portable accelerometer MSR-3C is programmed for test via a standard serial interface (New: also via USB (serial port emulation) to a PC using either of two optional software packages. After field recording is complete data is transferred back to the host computer for processing and analysis. Each portable acceleration data logger unit is powered by three built-in, rechargeable battery packs. Our portable acceleration data logger's recording function is controlled by three microprocessor-based digital data acquisition systems. Each of the systems is devoted to data acquisition on one of the three separate, three input channel sets. Channel sets may be tied together for simultaneous triggered acquisition, or allowed to operate independently. During active recording acceleration signals on each channel are digitized to 10 bit resolution and stored in digital memory within the unit. The MSR-3C offers 1 megabyte of data storage capacity per 3 channel set with 3 megabyte total data memory (12MB Optional). The MSR-3C also offers three input channels for optional temperature and temperaturerelative humidity probes. Temperature and relative humidity recording occurs independent of acceleration recording, at regular, user-programmable time intervals.

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-PLUS3D (SSP3D)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.
