The PANTHER Model EDR -4 series shock & vibration data loggers, monitors and recorders are self-contained, user-programmable acceleration sensor/recorders. 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 PANTHER model EDR-4 shock & vibration data monitor, logger and recorder is supplied with three or six high speed input channels: three differential inputs or three single-ended inputs. Recording may be selected from either channel set for any given recording session. On the standard PANTHER EDR-4 the three differential channels are connected to an internally mounted, triaxial PR accelerometer.
Single-ended channels are available as an option for external connection and use with voltage mode, piezoelectric accelerometers. The single-ended channels incorporate their own constant current excitation for powering voltage mode accelerometers. Other input signal conditioning configurations can be supplied on special order for any of our shock & vibration data monitor, logger and recorder.
The PANTHER model EDR-4M1 accelerometer logger and shock & vibration data recorder is supplied with three external single-ended accelerometer input channels only and no internal accelerometers. The PANTHER model EDR-4M4 accelerometer logger and shock & vibration data recorder is supplied with three external differential input channels only and no internal accelerometers. The EDR-4M4 accelerometer logger and shock & vibration data recorder may be used with external piezoresistive accelerometers as well as strain gauges, load cells, and other types of bridge-type transducers.
User adjustable gain and analog low-pass filtering are also available on the input signal conditioning circuits. The unit employs 4th order Bessel LPFs with tunable 3dB cut-off frequencies from 10Hz to over 2kHz. The recorder also provides user adjustable auto-zero offset correction which is tunable from a rate of no correction, ( ie. Absolute DC response ) to a fast correction rate of 1% of full scale per second.
This feature is designed to correct for transducer drift and DC offsets resulting from temperature variations, orientation changes, etc.
The PANTHER accelerometer logger and shock & vibration data recorder has been designed for applications requiring remote, unattended recording of high speed dynamic phenomenon over relatively long periods of time.
The rugged, shock hardened unit is ideal for conducting unattended recording sessions in harsh environments. Features available in the PANTHER accelerometer logger and shock & vibration data recorder make it an ideal instrument for applications ranging from in-depth transportation studies and laboratory simulations, to aircraft and spacecraft flight vibration recording to vehicular crash recording.
