DLC3010 Digital Level Controller
Introduction and Specifications

displacer, which rotates the torque tube shaft. This rotary motion is applied to the digital level controller, transformed
to an electrical signal and digitized. The digital signal is compensated and processed per user configuration
requirements, and converted back to a 4‐20 mA analog electrical signal. The resulting current output signal is sent to
an indicating or final control element.

DLC3010 digital level controllers are communicating, microprocessor‐based level, interface, or density sensing
instruments. In addition to the normal function of providing a 4‐20 milliampere current signal, DLC3010 digital level
controllers, using the HART
You can gain information from the process, the instrument, or the sensor using a Field Communicator with device
descriptions (DDs) compatible with DLC3010 digital level controllers. The Field Communicator may be connected at
the digital level controller or at a field junction box.
Using the Field Communicator, you can perform several operations with the DLC3010 digital level controller. You can
interrogate, configure, calibrate, or test the digital level controller. Using the HART protocol, information from the
field can be integrated into control systems or be received on a single loop basis.
DLC3010 digital level controllers are designed to directly replace standard pneumatic and electro‐pneumatic level
transmitters. DLC3010 digital level controllers mount on a wide variety of caged and cageless 249 level sensors. They
mount on other manufacturers' displacer type level sensors through the use of mounting adaptors.
249 Caged Sensors (see table 1‐6)
D 249, 249B, 249BF, 249C, 249K, and 249L sensors side‐mount on the vessel with the displacer mounted inside a cage
outside the vessel. (The 249BF caged sensor is available only in Europe, Middle East, and Africa.)
249 Cageless Sensors (see table 1‐7)
D 249BP, 249CP, and 249P sensors top‐mount on the vessel with the displacer hanging down into the vessel.
D 249VS sensor side‐mounts on the vessel with the displacer hanging out into the vessel.
D 249W wafer‐style sensor mounts on top of a vessel or on a customer‐supplied cage.

Specifications

Specifications for the DLC3010 digital level controller are shown in table 1‐1. Specifications for the 249 sensor are
shown in table 1‐3. Specifications for the Field Communicator can be found in the
