FUNCTION
Delavan’s Captrol 514 is a superior integral mount
Microcontroller Based R.F. Capacitance “Multi-Point”
Level Switch used in liquids and powder bulk solid
applications.
PRINCIPLE OF OPERATION
The Captrol 514 Microcontroller Based Multi-Point Level
Switch consists of solid state electronics
mounted in a cast aluminum explosion proof
enclosure. The integral unit utilizes a driven guard
designed to eliminate the effects of material build-up or
coatings that may cause false signals.
The sensing element section is energized with a
R.F. (radio frequency) signal approximately 2mHz.
When the process level changes, a change in
capacitance occurs resulting in a change in
frequency. The change in frequency is compared to
each of the previously established user set-points.
Depending upon the result of these comparisons,
the microcontroller with adjust (on or off) each relay.
