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
(thermocouple 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
