The indicator's large backlit display shows the measured value; an optional bar graph visualizes the measured value for a faster process overview. Editable plain text can display engineering units or TAG information. If a limit value is exceeded, a signal is output that opens the collector. The indicator requires no separate power supply and can be powered directly by the 4...20 mA loop. The device is Ex-certified and suitable for hazardous areas.
Advantages
4...20 mA measured value display
5-digit measured value display including dimension, bar graph and backlighting
No external power supply required
Version: glass-fiber reinforced plastic or aluminum, suitable for Ex applications
Simple 3-key operation; or via FieldCare PC software; or via the setup box, without power supply
International approvals; marine approval
Allows the HART® transmission protocol to pass through freely
Application
The display unit is housed in a field instrument housing with a microcontroller and LC backlit display. The display of measuring range, decimal point and offset can be easily configured via 3 keys after opening the housing, or on a computer using the FieldCare PC software.
