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
- 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
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.
DLC3010 Digital Level Controller: Mounts on caged and cageless 249
Communications Protocol: HART
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.
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
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
