The process transmitter registers an analogue measured value.
The sensor can be a transmitter, resistance, RTD or
thermocouple. Using the built-in linearisation function the signal
is converted to the required engineering units. This value can
be indicated in the built-in display and monitored using a max.
2 alarm set points. Set point infringements are permanently
displayed. An analogue output retransmits the displayed value
as either a current or voltage signal. Connected sensors can be
directly supplied with power from the unit.
