Xi Advanced Electronics

System Configurations Traditional Architecture, HART and Xi Communications

Some customers prefer not to mount electronics onto the probe, so a

"traditional architecture" version is offered. This probe sends raw millivolt

signals via a 7-conductor cable to the Xi electronics, Figure 1-2, which does

all heater control and signal conditioning in addition to its display/keypad

functions. The Xi Advanced Electronics is offered to support direct replace-

ment probes with either 120 volt or 44 volt heaters.
