Specifications and Reference Data
Figure A-4. Wall Mount Transmitter AC Power
Requirements
DC supply current requirements
Units powered by 12 VDC power supply may draw up to
1.2 A of current steady state.
Figure A-5. Wall Mount Transmitter DC Power
Requirements
Ambient temperature limits
Operating
–40 to 165 °F (–40 to 74 °C) without local
operator interface
–20 to 140 °F (–29 to 60 °C) with local
operator interface
The Local Operator Interface (LOI) will not display at
temperatures below -20 °C
Storage
–40 to 176 °F (–40 to 80 °C) with and without local
operator interface
Humidity limits
0–95% RH to 140 ° F (60 °C)
Altitude
2000 meters maximum
Enclosure rating
Type 4X, IEC 60529, IP66 (transmitter)
Transient protection rating
Built in transient protection that conforms to:
IEC 61000-4-4 for burst currents
IEC 61000-4-5 for surge currents
Turn-on time
Five minutes to rated accuracy from power up
Five seconds from power interruption
Start-up time
50ms from zero flow
Low flow cut-off
Adjustable between 0.01 and 38.37 ft/s (0.003 and
11.7 m/s). Below selected value, output is driven to the zero
flow rate signal level.
Overrange capability
Signal output will remain linear until 110% of upper range
value or 44 ft/s (13 m/s). The signal output will remain
constant above these values. Out of range message
displayed on LOI and the Field Communicator.
Damping
Adjustable between 0 and 256 seconds
