The electronic transmitters totally comply with the HART® protocol specification Revision 6.0,
so they include remote process variable interrogation, parameter setting and diagnostics.
The device is a 4÷20mA 2-wire transmitter, with FSK communication.
It is possible to read via HART® the following variables:



PV

: transmitter main measure;



SV

: % of the span;



TV

: analog output.



QV

: instrument temperature.

Please refer to

for the 4÷20 mA + Hart® modem connection.

In

the multidrop Hart® connection type is shown.

It is possible to purchase the Hart Server as an additional product; this is a software including all
the interrogation, configuration and diagnostics functions required by the Hart® 6.0
