1 FIELDVUE DLC3010 Digital LevelControllerThe FIELDVUE DLC3010 Digital Level Controller is usedwith Level sensors to measure liquid Level , the Level ofthe interface between two liquids, or liquid specificgravity (density). Changes in Level or specific gravityexert a buoyant force on a displacer, which rotates atorque tube shaft. The Digital Level Controller convertsthis rotational motion to an electronic DLC3010 is a communicating,microprocessor-based instrument that can beconfigured to sense the Level , interface Level , ordensity of liquids. In addition to the normal function ofproviding a 4 to 20 milliampere current signal, theDLC3010, using HART communications protocol,gives easy access to information critical to processoperation.

2 You can obtain information about theprocess, instrument, or sensor using the 475 or 375 Field Communicator. The DLC3010 can be used inanalog or HART Digital signaling mode with theEmerson Automation Solutions DeltaV connection for HART communication may bemade at any point in the field wiring that meets theHART impedance requirements. Configuration,calibration, diagnostics, parameter review, signalmonitoring and alert monitoring are all availableW7977-2through the HART protocol. Information from the fieldcan be integrated into control systems or be receivedon a single loop DLC3010 Digital Level Controller is designed todirectly replace standard pneumatic and electroniclevel transmitters.

Total shunt impedanceacross the master device connections (excluding themaster and transmitter impedance) must be between230 and 600 ohms. The transmitter HART receiveimpedance is defined as:Rx: 42K ohms and Cx: 14 nFIn point-to-point configuration, analog and digitalsignalling are available.
