Application Notes

Here's how some of our customers used this product.

Datalogging Process Signals

The Background: Our customer is a facility that needs to data log a 4-20mA process signal in a small control cabinet.

The Problem:* The control cabinet needs to remain completely sealed with no wires protruding from it nor external devices mounted to it.

The Solution: We recommended the MadgeTech Process101A which is battery powered and, at just 1.4 inches x 2.1 inches x 0.6 inches, is small enough to fit inside tight spaces.
