Epsilon Technology Corp. logo.

Provides an Inexpensive Solution for Digitally Recording Extensometer Output

The DSCUSB functions as a signal conditioner with a digital USB output, offering a plug-and-play interface between strain-gaged extensometers and a computer via USB. This enables direct data capture without requiring additional data acquisition electronics or an input channel in the testing machine's controller. When purchased from Epsilon with an extensometer, the pair are calibrated and strain readings transmitted via USB are calibrated values.

Calibration of an extensometer is managed within the DSCUSB, accommodating up to 7 linearization points and providing output readings in mV/V, mm, or inches. The user-friendly software logs data to the computer and features digital readouts and a trend chart.

The DSCUSB can be interfaced with existing software solutions by controlling it through a set of ASCII commands via its virtual COM port.

A USB cable is included.
