6 - 114 Service Manual

A HART temperature sensor may have a PV unit code Ohms, and a SV

unit code Celsius. The required sensor value is temperature in Celsius,

and this is translated into the FlexConn PV, and the Ohms value is

translated into the FlexConn SV.

Translation is performed in the order: PV (Distance, Temperature,

Pressure, and Density), SV (Distance, Temperature, Pressure, and

Density), TV (Distance, Temperature, Pressure, and Density).

The required sensor value read from the generic HART devices will be

converted into SI Units within the FlexConn PV as shown in TABLE 6-9.

The other sensor values of a generic HART device are not converted,

and they are simply translated from the HART device environment into

the FlexConn environment SV and TV.
