4 Average temperature measurement with MPT / RTD
4.1 Introduction MPT / RTD
The 762 VITO MRT Interface can be used for interfacing 1 through 3 separate RTD spots which are in a 3 wire
configuration or an MPT probe (Multiple Pt100 spots) consisting of 1 through 14 RTD's with 2 common ground
wires (refer to figures 4.1 and 4.2).
The RTD elements below the product level are used to determine the average product temperature, in respect to
product immersion depth and hysteresis mechanisms and to actual valid level, last valid level or manual level.
The RTD elements above the product level are used to determine the average gas temperature, in respect to gas
immersion depth and hysteresis mechanisms and to actual valid level, last valid level or manual level.
4.2 Commissioning of MPT / RTD
The commissioning of the optional board should be performed after the basic commissioning of the level gauge,
or indicator.
