HART Communication
Fig 16: HART connection for the 4-20mA current loop
•
The 4 to 20mA output represents the digital Primary Variable [PV].
•
The primary variable can be setup for Differential Pressure, Static Pressure or Line
Temperature, for Tek-Bar 3800XP Multivariable Transmitter.
•
By default, the 4-20mA output is set for Differential Pressure with a Range of 0 to 100” H
2
O.
•
This can be modified to suit customer requirements using a HART master such as a 475 HHT
or AMS PC based system.
•
The 4-20mA output can have a damping value applied to smooth out any sudden changes on
the current loop, if required.
•
Damping is entered as an integer representing seconds.
