Standard Digital Valve Positioner Measuring Liquid Level With Level Sensors

Fisher FIELDVUE DLC3010 Digital Level Controller

The Fisher FIELDVUE DLC3010 digital level controller helps you gain easy access to information critical to your process operation. Gather information about the process, instrument, or sensor using the 475 or 375 Field Communicator. The DLC3010 digital level controller can be used in analog or HART® digital signaling mode with the DeltaV™ system.


  • 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.

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 communications protocol, give easy access to information critical to process operation.

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.

Available Configurations

DLC3010 Digital Level Controller: Mounts on caged and cageless 249 sensors.

Function: Transmitter

Communications Protocol: HART

Input Signal

Level, Interface, or Density: Rotary motion of torque tube shaft proportional to changes in liquid level, interface level, or density that change the buoyancy of a displacer.

Process Temperature: Interface for 2‐or 3‐wire 100 ohm platinum RTD for sensing process temperature,or optional user‐entered target temperature to permit compensating for changes in specific gravity.

Output Signal

Analog: 4‐20 milliamperes DC (direct action—increasing level, interface, or density increases output; or reverse action—increasing level, interface, or density decreases output)

High saturation: 20.5 mA

Low saturation: 3.8 mA

High alarm: 22.5 mA

Low Alarm: 3.7 mA

Only one of the above high/low alarm definitions is available in a given configuration. NAMUR NE 43 compliant when high alarm level is selected.

Digital: HART 1200 Baud FSK (frequency shift keyed)

HART impedance requirements must be met to enable communication. Total shunt impedance

across the master device connections (excluding the master and transmitter impedance) must be between 230 and 1100 ohms. The transmitter HART receive impedance is defined as: Rx: 42K ohms and Cx: 14 nF

Note that in point‐to‐point configuration, analog and digital signalling are available. The instrument may be queried digitally for information, or placed in Burst mode to regularly transmit unsolicited process information digitally. In multi‐drop mode, the output current is fixed at 4 mA, and only digital communication is available.
