In the industrial automation & manufacturing industries, there are numerous situations where it is vital to convert physical force into a measurable electrical output; in most cases, you will need a strain gauge or load cell. The question remains, however, of how to handle, convert, and log these electrical signals.

This is where I-87016W should be your NO.1 choice! It not only processes the data from load cells or strain gauges, but also features linear mapping that generates intuitive and synchronous results. Using a user-defined correspondent table, I-87016W converts analog force data directly into a readable weight output.
