Specifications and Reference Data
A.3 Functional Specifications
A.3.1 Range and Sensor Limits
Zero and Span Adjustment Requirements
(
HART and Low Power)
Zero and span values can be set anywhere within the range limits stated in Table A-1 .
Span must be greater than or equal to the minimum span stated in Table A-1 .
Service
Liquid, gas, and vapor applications
4–20 mA (Output Code A)
Output
Two-wire 4–20 mA, user-selectable for linear or square root output. Digital process variable
superimposed on 4–20 mA signal, available to any host that conforms to the
HART protocol.
Power Supply
External power supply required. Standard transmitter (4–20 mA) operates on 10.5 to 55 V dc with
no load.
