FIELDVUE DLC3100 and DLC3100 SIS digital level controllers are HART® communicating instruments that are used with level sensors to measure liquid level, level of the interface between two liquids, or liquid density (not applicable to DLC3100 SIS). The DLC3100 converts this measurement into 4-20 mA transmitter signal.
Unless otherwise noted, the information in this document applies to both DLC3100 and DLC3100 SIS.
However, for simplicity, the DLC3100 model name will be used throughout.
Safety
The DLC3100 SIS is certified to be SIL2 capable (HFT=0) in accordance to IEC61508 standard. It is designed and capable to be used in safety function to achieve a tolerable risk for a process hazard. It allows potential risk reduction for people, systems, devices and processes. The DLC3100 SIS is identified by a label affixed to the terminal box cover.
Ease of Use
Intuitive Local User Interface with four push buttons and LCD allow you to setup and calibrate the device without external tool.
Using Guided Device Setup digital level controller start-up is straightforward and fast. Level and temperature alarms, specific gravity tables, calibration trim and trending are readily configurable.
Dynamic Temperature Compensation
Integration of process fluid temperature when needed, enables density compensation to maintain process variable accuracy.
An Internal Temperature Sensor enables consistent performance of the digital level controller despite ambient temperature changes. With a temperature input signal, either via HART protocol or an RTD connected to the instrument, the digital level
controller can also automatically compensate for specific gravity changes due to temperature. A user-supplied table of up to ten linear segments may be entered to implement this feature.
Maintenance Assistance
HART registered DLC3100 provides device diagnostics and recommended actions to restore instrument functionality
Alert History
Alert Record saved in the instrument helps you to troubleshoot when there are abnormalities.
Rugged Construction
Mechanical safeguards designed into the digital level controller help it to withstand physical abuse often incurred during installation or in transport, without compromising performance. The lever assembly is pinned at the neutral position when the coupling access door is open, providing shipping stabilization for a separate transmitter purchase.
Integration
Modular design allows interchangeable of components. Part kits are available for spare parts replacement.
The DLC3100 is designed to be mounted on a wide variety of 249 caged and cageless level sensors as well as on 3rd party non-Emerson displacers from Masoneilan, Foxboro-Eckardt, and Yamatake, through the use of mounting adaptors.
Reliability
Accurate, high-gain analog-to-digital conversion enables measurement of small changes in the process variable. This allows the DLC3100 to be used in difficult liquid level, interface, or density applications. In addition, an adjustable input filter
and output damping help to attenuate displacer-induced ripple in the output signal due to liquid turbulence.
The DLC3100 instrument has fully encapsulated electronics that resist the effects of vibration, temperature, and corrosive atmospheres. An IP66 wiring terminal box isolates field wiring connections from other areas of the instrument.
