USB Module Handles Sound/Vibration Analysis

With four independent 24-bit integrated electronics piezoelectric sensor inputs, the DT9837A is a high-performance USB module for sound and vibration analysis. The sensor inputs are synchronized with a tachometer input to provide data streams matched in time for field or laboratory use. A read-back channel from the analog output guarantees perfect correlation of all signals with the input stream, the output stream, and the tachometer. The different tachometer pulse phase measurement modes allow measurements of the rotation speed as well as precise tachometer pulse phase measurement with a resolution of 37 ns or 0.002° resolution at a rotation speed of 10,000 rpm. The module features programmable sampling rates from 195 Hz to 52.7 kHz. No power supply is needed because the module is powered through the USB connection to a PC or laptop. The DT9837A costs $1795 and is shipping now. DATA TRANSLATION, Marlboro, MA. (508) 481-3700.
