A.2.3 4-20 mA HART
Output
Two-wire, 4-20 mA. Digital process variable is superimposed on 4-20 mA signal, and
available to any host that conforms to the HART protocol. The digital HART
®
signal can be
used in multidrop mode.
(15) The Damping parameter defines how fast the device responds to level changes (step response). A high value makes the
level steady but the device reacts slowly to level changes in the tank.
