DI-730 High Voltage USB Data Acquisition System with Windaq software. Features 8 wide range differential analog input channels, 150,000 Samples per second throughput, 14-bit measurement resolution, and full scale ranges of ±10, ±100 mV, ±1, ±10, ±100, ±1000 V full scale.
The DI-730-USB offers 14-bit resolution and 150,000 Samples per second waveform recording capability. Use the DI-730 for wide dynamic range measurements, especially those involving AC or DC electric motors. Examples include paper, aluminum, and steel mills; high speed trains; and rail and seagoing locomotion. The high sample rate, exceptional isolation, and CMR characteristics make it well-suited for maintenance and troubleshooting of DC drive systems. Other applications include RPM measurements from motor/generators, supply voltage and current measurements, and field current measurements from drive-roll, braking, and take-up motors.
