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.
