Fisherr FIELDVUEt DLC3020f Digital Level Controller for FOUNDATIONt fieldbus
The FIELDVUE DLC3020f digital level controller is a fieldbus communicating instrument used to measure liquid level or the level of interface between two liquids using displacement sensor technology.
In addition to the normal function of reporting process level PV, the DLC3020f, using FOUNDATION fieldbus protocol, gives easy access to information critical to process operation and will readily integrate into a new or existing control system. AMS Suite: Intelligent Device Manager or the 475 Field Communicator can be used to configure, calibrate, or test the digital level controller.
The DLC3020f is also designed to directly replace pneumatic, analog, or HARTr transmitters/ controllers. It can be mounted on a wide variety of 249 cageless and caged level sensors as well as on other displacer type level sensors through the use of mounting adaptors.
Features
ν Ease of Use The DLC3020f, a fieldbus level or interface transmitter, features the latest in user interface technology. In addition to reporting the PV, the DLC3020f can act as a PID controller or level switch.
ν Guided Setup and Calibration Leads you through instrument setup, process fluid selection, and calibration in an easy to use format.
W9954-1_DLC3020f
ν Dynamic Temperature Compensation Integration of process fluid temperature, when needed, enables density compensation to maintain PV accuracy.
ν Simple Process Fluid Configuration The capability to easily select/define process fluids allows for fluid changes without requiring re-calibration.
ν Calibration/Setup Logs Saved in Instrument
Logs, including calibration, instrument setup, and process fluid data, can be saved for future reference or re use in batch or continuous applications. The instrument stores up to 30 logs.
ν Performance/Reliability State of the art Emerson advanced electronics provide increased performance and reliability.
