DT9837

Portable USB Module for Sound and Vibration

The DT9837 is a highly accurate USB data acquisition module that is ideal for portable sound and vibration measurements. Four 24-bit IEPE (ICP) sensor inputs are synchronized with a tachometer input to provide data streams that are matched in time for field or laboratory use. The 38 segment clock-time conversion of the Delta-Sigma A/Ds is offset in software to provide this time correlated data. The rugged small module is self-powered via the USB connection to a PC laptop. BNC connections are provided for all I/O signals for secure and easy-to-use operation.

A board-only OEM version is also available.

Key Features:

4 simultaneous, 24-bit Delta-Sigma A/D channels for high resolution measurements.
Support for four IEPE inputs, including 4mA current source and AC or DC coupling.
Portable operation. No external power supply needed. Runs on USB power.
Tachometer input support in the A/D data stream for synchronizing measurements.
Sampling rate of over 52kHz to meet your application need.
Analog input range of ±10V with software selectable gains of 1 and 10.
One 24-bit Delta-Sigma D/A converter with single-value or ultra-smooth waveform capability.
Programmable triggers for analog input operations for maximum flexibility. Choose a software trigger, TTL trigger, or analog threshold trigger.
Simultaneous operation of the A/D and D/A subsystems for maximum performance.
Supported by all DT-Open Layers for .NET Class Library compliant software to meet any application need.

The DT9837 has 4 simultaneous IEPE sensor inputs plus a synchronous tachometer input and is ideal for portable sound and vibration measurement applications.
