The CEM DT-178A is an advanced engineering tool designed to record acceleration and vibration data in three axes (3-Axis). The device monitors and documents vibrations, shocks, and instantaneous peaks, with the unique ability to record the moment of "Freefall," making it the primary choice for monitoring the safety of sensitive shipments and heavy industrial equipment.
Key Features:
-
3-Axis Recording (X, Y, Z): Provides a complete history of shock and vibration conditions experienced by the product from all directions.
-
Instantaneous FFT Analysis: Measures and calculates spectral data using Fast Fourier Transform technology from 0 to 60 Hz.
-
Advanced MEMS Sensor: Relies on a high-precision semiconductor (MEMS) sensor to ensure data stability and reliability.
-
Massive Flash Memory: Storage capacity of up to 8 MB, allowing the recording of approximately 504,126 total samples.
-
Freefall Monitoring: Records the exact time of any freefall, which is crucial for insurance claims and assessing damage during shipping.
Advanced Technical Capabilities:
-
Fast Sampling Rate: The sensor's sampling rate reaches 256 Hz to capture the finest vibrations.
-
Wide Measurement Range: Withstands and records acceleration up to ±18g with high accuracy.
-
Flexible Operating System: Supports real-time operation mode and motion detection mode.
-
Integrated USB Interface: For easy data transfer to a computer and analysis via included software that supports Windows systems.
