APCI-3701 Length Measurement Board

Quick Overview

The APCI-3701 is a PCI length measurement board with 8 or 16 channels for inductive transducers, LVDT or half-bridge sensors. The APCI-3701 includes a sinus generator supply. 64-bit drivers for Windows and Linux as well as programming samples are included, real-time drivers for Windows and Linux are available on request. Software includes 50 pre-calibrated transducer options and easy step by step instructions for calibrating transducers to individual channels.
