Level Switches and Fluid Level Switches for Industrial Process Measurement and Automation
FCI liquid level/interface switches feature thermal
dispersion technology in which the temperature difference
between the two RTDs is greatest in the absence of liquid
and decreases when the level element is submerged, cooling
the heated RTD.
An electronic control circuit converts the RTD temperature
difference into a DC voltage signal. Both signals are
provided at output terminals to drive two adjustable-setpoint
alarm circuits.
|
Both alarms are independently field configurable for liquid
level, interface or temperature operation. Since all process
media exhibit different heat transfer capabilities, highly
sensitive FCI liquid level/interface controllers may be
specifically calibrated to detect difficult interfaces
between fluids -- including liquids, gases, slurries and
foam regardless of their physical properties.
FCI has designed and developed three standard thermal level
switch product series to meet a broad range of performance
and environmental application requirements. Each FCI level
switch group can be distinctly identified by the following
listed general instrument characteristics: |

FCI has designed and developed four standard thermal flow switch
product series to meet a broad range of performance and
environmental application requirements. Each FCI flow switch group
can be distinctly identified by the following listed general
instrument characteristics:
