Marlboro, MA Data Translation offers the DT9837A, a high performance USB module for sound and vibration analysis. DT9837A has four independent 24-bit IEPE (integrated electronics piezoelectric) sensor inputs that 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 measure modes allow measurements of rotation speed and precise tachometer pulse phase measurement with a resolution of 37 ns or 0.002 degree at a rotation speed of 10,000 rpm.
“Numerous vibration applications have contributed to the advanced features of the DT9837A. It’s exacting measurement capability is unmatched by any other, while its USB palm-sized module format can be easily used in portable field applications,” states Fred Molinari, Data Translation president and CEO.
This rugged small module is self-powered via the USB connection to a PC or laptop, no external power supply is needed. This makes it ideal for portable measurement applications. Additionally, two modules can be triggered simultaneously for perfectly synched measurements over both, company says.
