Cabling for Remote Detector/Converter
Honeywell offers the excitation and signal cables as a set under a separate model
number (Model Number KIW-XXX-XXX). Commercially available cables can be
used. The selection of the signal cables depends on certain conditions:
• fluid conductivity,
• length of cable, and
• diameter of the detector.
Figure 9 shows the relation between fluid conductivity and cable length.
