Note.
nd – the hot product temperature can be measured by a single or dual RTD. For the dual RTD, the primary
2 RT and RT Deviation
input is always the one displayed as 'Hot Product'.
The secondary RTD enables a self-check facility which can be used to maintain the integrity of primary and secondary
resistance thermometer devices. Any imbalance between the first and second RTD greater than the trip level entered in the
appropriate scroll automatically causes the flow to divert, regardless of the primary temperature measurement.
