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

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 / sushil d. jambhulkar

TO COMPENSATE THE EFFECT OF TEMP & RESISTANCE ON mV WE USE
COMPENSATED CABLE FOR THERMOCOUPLE.

Answer / ponnamalla venkata satish

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

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

Answer / aebrahim

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

1 Answers   Bapco Bahrain Petroleum Company,

A temperature sensor (RTD) connected via a temperature transmitter is adjusted to give an output of 4ma at 60 deg and 20 ma at 600 deg. This output (4-20ma) from the transmitter is connected to an IGBT-inverter to control a high speed (-12,000 to +12,000 RPM) DC motor. And in the inverter it is programmed as, for 4ma the motor speed will be -3,000 RPM and for 20ma the motor speed will be +10,000 RPM. The question is : If the motor speed is +5,500 (RPM), what will be the temperature? (-sign indicates that the motion is in reverse direction).

Technician A says that a fuel tank sending unit will have a high resistance only when the tank is full. Technician B says that its resistance when the tank is full depends on whether the sending unit is designed for use with a bimetallic gauge or with a magnetic gauge. Who is correct?
