Description

The MotionMaster R (EDR-6DOF) is a portable accelerometer, digital angular rate sensor / logger and recorder designed to measure shock, vibration, temperature and (as an option) humidity, pressure, or resistance-bridge devices. The programmable unit tags all angular velocity and linear acceleration events with a time and date to provide a time history of the dynamic environment experienced during a recording session.

The EDR-6DOF portable acceleration data logger / recorder offers you a time-tested reputation for proven performance and reliability. The EDR-6DOF portable acceleration data logger / recorder is built upon the EDR-3C portable accelerometer series platform, with hundreds of successful installations since 1989. Each portable acceleration data logger / recorder is powered by a specially designed 9 Volt battery pack.

The EDR-6DOF portable acceleration data logger / recorder is used in conjunction with DynaMax programs and downloads the EDR-6DOF’s memory via an IBM compatible personal computer using serial & USB  (serial port emulation).  Together, the EDR-6DOF portable acceleration data logger / recorder and the DynaMax software program provide a powerful tool for accurately recording and analyzing dynamic environments.

 

Operation of the Instrument

During recording acceleration and angular rate signals are digitized to 10 bits and stored in on-board memory. The choice of a 10-bit A/D allows for precision, low noise measurements while still making effective use of available data memory and battery power in comparison to 8 or 12-bit systems. The EDR-6DOF portable acceleration data logger series recorders are capable of recording nearly 3 hours of equivalent real-time data over a typical 100 Hz vibration analysis bandwidth for typical ground applications. If you're interested in getting a handy spreadsheet for use in calculating memory usage based on your own specifications, contact us and we're happy to e-mail it to you.

Triggering

Advanced data management capabilities of the EDR-6DOF portable acceleration data logger / recorder allow the unit to measure and record over 5,000 separate 6-channel waveform sets consisting of linear acceleration and angular rates. IST's unique "Event Type Partitioning" of separate time-triggered and event-triggered data may also be performed during recording. This feature makes post-collection data reduction and analysis easier. The length of each event is also selectable between event types, enabling the unit to be optimized for capture of both acceleration and angular rate data during a single recording session.

 

Temperature and Humidity Recording

The EDR-6DOF portable acceleration data logger / recorder series also measures and records environmental temperature using a sensor built into the unit and/or an externally connected temperature sensor. Optional internal and external relative humidity sensors are available.

 

Pressure Recording

The EDR-6DOF portable acceleration data logger / recorder series can measure various pressures -- atmospheric pressure, or differential pressure for shipment under positive pressures, and other configurations. These can be provided as external sensors.

Strain, Load and other Resistance Bridge (strain-gage based) Sensors

The EDR-6DOF portable acceleration data logger / recorder series offers alternative sensor configurations as well. The EDR-6DOFM4 portable acceleration data logger / recorder can be used to provide 3 channels of strain and three channels of internal angular rates. Other configurations are available, contact IST for details on these configurations.

Auto-Zero Offset Control

The EDR-6DOF portable acceleration data logger / recorder can be provided with automatic digital offset correction between recording events, as an option. This feature compensates for DC offset resulting from temperature variation, as well as changes in orientation. The standard EDR-6DOF portable acceleration data logger / recorder comes standard with auto-zero on linear accelerometers and without it on angular rates. Configurations are available with any combination of auto-zeroing or non-zeroed recording.

 

Sensors

Each EDR-6DOF portable acceleration data logger / recorder is supplied with a specially designed and calibrated built-in triaxial accelerometer, and built-in triaxial angular rate sensor. The internal accelerometers and rate sensors are piezoresistive devices, offering superior low frequency response characteristics and extremely low power consumption. Acceleration/rate recording can be configured for the internal triaxial accelerometer channels or up to 3 optional external accelerometer inputs.

 

External Accelerometers and Rate Sensors

The optional external accelerometer input channels are designed for use with "low bias" versions of ICP piezoelectric voltage mode devices.  External channels provide signal conditioning, filtering, and constant current excitation for use with voltage mode accelerometers.

As an option, IST can provide an external rate sensor package, or rate/linear accel sensor package for connection to the EDR-6DOF portable acceleration data logger / recorder.

 

External Input Triggering

An external bi-directional trigger channel is available on all EDR-6DOF models.

 

Flexible USB or Serial Communication

The EDR-6DOF acceleration data logger / recorder offers a special serial communications port for standard or high speed serial data transfer to a host PC. The specially designed serial port enables standard communications at 9600 Baud as well as high speed data transfers at 115 kBaud. USB (serial port emulation) is now also available.

 

Advanced Programmability

The acceleration data logger / recorders are set up using a standard PC serial port or USB connection along with IST's DynaMax software package. After field recording, data is transferred back to the host PC for processing and analysis. The EDR-6DOF portable acceleration data logger / recorder is completely user-programmable for accurate recording of either (transient) shock and/or pseudo-stationary vibration data along with rate data. The instrument may be set up to operate under both event (amplitude-based) and/or time (periodic) triggered recording.

 

Data Management

Several different data management features are available for handling large numbers of captured time histories. Fill & Stop memory mode records all frames satisfying the trigger condition sequentially in time until the digital memory within the instrument is filled. A second Overwrite memory mode option records a selectable number of events having the largest RMS levels of all events measured.

 

Sliding Window Overwrite Mode (SWO)

The EDR-6DOF portable acceleration data logger / recorder offers a powerful new feature called Sliding Window Overwrite (SWO) developed exclusively by IST. SWO provides the advantages of overwrite mode and much more. With SWO the field test period is effectively partitioned into a user selectable number of time windows or bins. The size of the time windows is selected by the user. Event overwriting can only occur within the respective time windows.

 

Improved Laboratory Simulation

SWO enables the user to uniformly capture selective highest-level "time windows" of data during a field test. Recorded SWO can be processed with IST's DynaMax DM-psd software module to generate a separate PSD (Power Spectral Density) for each time window, or any subset of the data desired.

 

Vibration Test System Compatibility

Data recording with all EDR-6DOF acceleration data logger / recorder models can be processed with IST software for direct compatibility with virtually all digital vibration controllers.

 

Performance History

The EDR-6DOF portable acceleration data logger / recorder is built upon the EDR-3C platform. The EDR-3C series recorders have been used in a broad range of high-performance applications world-wide for several years. A few of the more prominent application using this platform include:

  • The recorder of choice by damage prevention professionals at most major U.S. Railroads
  • Mandated by U.S. Auto Club as the "crash recorder" for all INDY race cars
