Q: We are in need of a signal converter that converts a 4-20mA logarithmic signal into a 4-20mA linear signal. We need one input and one output per device. Do any of your devices perform this function?

A: We offer several models of signal converters which have look-up table linearization/characterization capability.

The SIY is an output loop-powered unit that can be configured for up to 85 ordered pairs. With this model, each ordered pair must be keyed in using the provided configuration software.

The CPT is a line-powered model that can be configured for up to 128 ordered pairs. The ordered pairs are computed with a spreadsheet, saved as a two column CSV file and then loaded into the provided configuration software. The configuration is then loaded into the CPT.

With both models you specify the X and Y values so you can cluster points at the most non-linear part of your table.
