3.6 Sensor Placement
Proper sensor placement is essential. It can eliminate many problems in
the total system. The probe should be placed so that it can detect any
temperature change with little thermal lag. In a process that requires
fairly constant heat output, the probe should be placed close to the
heater. In processes where the heat demand is variable, the probe
should be close to the work area. Experimenting with probe location
can often provide optimum results. Some units are shock sensitive and
require care in handling and installation. To avoid current feedback from
zone to zone and from zone to RS-232 communications, ungrounded
thermocouples are recommended. Thermocouple wires should not be
placed in the same conduit as the power lines.
