If mVolts can drop by resistance of wire as compare to mA, then how thermocouple mV reaches in CCR..

Answer / ravinder tanwar

It depends on quqlity of cable and generally it is
specified by the cable manufacturer that for a perticular
distance what will be the loses and we add that quantity in
our logic for accurate value

Answer / praful lilhare

bcoz use the specialy manufactured t/c cable and for each
type of t/c we use different t/c cable of that t/c material

If mVolts can drop by resistance of wire as compare to mA, then how thermocouple mV reaches in CCR..

Answer / jayakrishnan unnikrishnan

First upon CCR not receiving any mv,it is receiving only ma.
mv is going to the transmiter and the transmiter giving
output to panel and console.
& voltage drop , Thermo couple extension cable is not a
normal signal cable it is depends on the thermocouple type.
consider K type thermocouple so the extension cable should
be Nickel Aluminium, b'coz Nickel Chromium is the K type.
it will avoid voltage drop.

Answer / ponnamalla venkata satish

thats why we use single stand not multi core cable for
thermocouple measurement

If mVolts can drop by resistance of wire as compare to mA, then how thermocouple mV reaches in CCR..

Answer / rajesh

Each type of themocouple different types of metals winding are used Example k-type of thermo couple used cromium aluminium metals are used, like j,s,t ect. This metals used as per thermo couple mvolts droping is reducedu

Is This Answer Correct ?    0 Yes 1 No

If mVolts can drop by resistance of wire as compare to mA, then how thermocouple mV reaches in CCR..

Answer / aebrahim

the resistance of thermocouple is les than resistance of
normal cable so voltage drop across wire not too big
