Fisher™ FIELDVUE™ DLC3100 and DLC3100 SIS Digital Level Controllers
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. Features 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. X1456 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.

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. Figure 1.

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 density. Output Signal Analog: 4 to 20 mA 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(2): > 21.0 mA Low Alarm(2): < 3.6 mA Digital: HART 1200 Baud Frequency Shift Keyed (FSK) 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 600 ohms. Supply Requirements (see figure 3) 12 to 30 volts DC; 25 mA Instrument has reverse polarity protection. A minimum compliance voltage of 17.75 VDC (due to HART impedance requirement) is required to guarantee HART communication.

Temperature compensation can be implemented to correct for process density changes. Process Density The sensitivity to error in knowledge of process density is proportional to the differential density of the calibration. If the differential specific gravity is 0.2, and error of 0.02 specific gravity units in knowledge of a process fluid density represents 10% of span.
