Dynamic Signal Test And Analysis System-DE944

DE-944 dynamic signal test and analysis system, is designed for strength and life assessment test, especially for large-scale structure system. Capable of accurate measurement of highly dynamic signals.

Quantity:
  • DE944
  • Dynatronic
Scope

DE-944 dynamic signal test and analysis system, is designed for strength and life assessment test, especially for large-scale structure system. Capable of accurate measurement of highly dynamic signals, the DE-926U accommodates arrange of bridge type sensors (force, pressure, displacement, velocity, and more) as well as piezoelectric sensors, using an optional charge conditioner.


Features

• Modular design, flexible channel setup, Ethernet expandability

• Max. 20MHz transient sampling rate, preamplifier with adjustable gains, frequency response DC - 1MHz

• Supports EID, programmed strain calibration

• Support TEDS sensors

• Transient signal capture, multiple trigger methods (manual, external, signal triggering)

• Advanced System of Chip (SOC) to control Gigabit Ethernet and save data to computer with up to 32MB/s speed in real time

• Dedicated DSP system per channel

• Real-time DMA for fast, stable, lossless data transfer

• Remote sensing technology to ensure bridge excitation stability eliminating the effect of long wire resistance

• Dedicated 16-bit SAR AD converter per channel

• Possess a strain stress channel field self-test function, you can quickly get the current state of the channel
