The FIELDVUE DLC3010 digital level controller is used with level sensors to measure liquid level, the level of the interface between two liquids, or liquid specific gravity (density). Changes in level or specific gravity exert a buoyant force on a displacer, which rotates a torque tube shaft. The digital level controller converts this rotational motion to an electronic signal.

The DLC3010 is a communicating, microprocessor-based instrument that can be configured to sense the level, interface level, or density of liquids. In addition to the normal function of providing a 4 to 20 milliampere current signal, the DLC3010, using HART® communications protocol, gives easy access to information critical to process operation. You can obtain information about the process, instrument, or sensor using an Emerson Field Communicator. The DLC3010 can be used in analog or HART digital signaling mode with the Emerson Automation Solutions DeltaV™ system.

Fisher™ FIELDVUE™ DLC3010 Digital Level Controller Features

For quick analog transmitter replacement, the instrument may be configured with default sensor data, zero level offset, differential process SG, and zero/span procedure only.

Accurate, high-gain analog-to-digital conversion enables measurement of small changes in the process variable. This allows for use in difficult liquid level, interface, or density applications.

An internal temperature sensor enables consistent performance of the digital level controller, despite ambient temperature changes.

Mechanical safeguards designed into the digital level controller help to withstand physical abuse often incurred during installation or in transport, without compromising performance.

Field wiring connections are in a compartment separated from the electronics. This protects the electronics from any moisture brought into the housing by the field wiring.

Includes self-diagnostics that detect an error that may render the process variable measurement inaccurate.
