Temperature Controllers
Series HTI 16
Integral Controller / Monitoring-Combination
The device convinces by being optimally matched to our trace heat-
ing systems, compact form and simple handling. Easy mounting us-
ing the mounting plate that is designed as cooling unit and modern
connection systems are self-evident.
The HTI 16 Temperature Controller controls the temperature of
heating conductor. Temperature measurement takes place via the
resistance change in the heating wire without further sensors.
Rather than point measurement, the Integral Controller measures
the average temperature over the entire length / surface of the
heating system directly from the heating wire and registers a tem-
perature change immediatley without any delay. The measured
value corresponds to the temperature profi le of the entire heating
system rather than the temperature at a single point. A special nickel
alloy is used as heating wire. For HTP 16 Controller-Monitoring you
need an extra PT 100.

The HTI controller is always calibrated on the corresponding heating
circuit. On supply of a heating system with an assigned control-
ler system, the device is factory-set. The heating system and the
controller are then coded accordingly. Calibration is stored as a
mode and can be performed without undue effort in the event of
a device change.
The measured value corresponds to the temperature profi le of
the entire heating system rather than the temperature at a single
point.
