6.10.2 VITO Interface Types
For temperature and/or water level measurement, a proper VITO probe
must be connected to the FII-VT module, using a VITO interface.
There are 3 VITO interface types:
762 VITO MTT interface for 16-spot temperature measurement (ther-
mocouple principle) and optionally a water bottom measurement
762 VITO LT interface for 9-spot temperature measurement (thermo-
couple principle) and optionally a water bottom measurement
762 VITO MRT interface for Multiple Resistance Thermometer and
multi-spot (resistance variation principle) measurement
