This is to discriminate the wire-break of sensor and the
zero value of measured parameter.
ex:If pressure transducer measures 0 bar pressure,it will
send 4mA signal to the monitoring unit(EX:PLC).in case ,if
there is any break(dis-continuity) in wire then PLC senses
the 0 mA and gives alarm or shutdown depends on the
important of that parameter.
