Application of Twisted Pair Cable:

*Twisted pair cabling is a form of wiring in which two
conductors are wound together for the purposes of canceling
out electromagnetic interference (EMI) from external
sources.

*Twisting wires decreases interference because the loop
area between the wires is reduced.

*The two wires typically carry equal and opposite
signals which are nutralized because of phase shift.

Answer / banibrata mukherjee

Twisted pair of wires is used in order to avoid inductive
coupled interference signals.As a result of twisting the
loop area between the conductors is reduced & so induced
current in the wires is also reduced & external magnetic
field effect is also minimized.

Answer / kavitha

twisted pair cables are very qualitative in nature as they
prevent electromagnetic interference from external sources
and crosstalk from external wires. They are majorly used in
telephone networks, data networks and cable shielding. Our
twisted pair cables are of two types, which are: Shielded
Twisted Pair Cables: These cables protect cable from
external electromagnetic interferences and are used with
token ring networks. Unshielded Twisted Pair Cables: These
are the unshielded twisted pair cables which are highly
flexible and long lasting in nature. Our cables are used in
many Ethernet networks and telephone systems

Answer / singh

Twisted pair of wires is used in instrumentation mainly to
reduce the eddy current loss.

Answer / parmar.ic@gmail,com

Twisted pair of wires is used in instrumentation because it
in information Ethernet application and in instrumentation
are many wires . and it is provided of proper ground of the
instrumentation so it is twisted pair wire are avialable of
one wire is puase and anther is ground.
many some resion of the twisted pair of wire is used in
instrumentation first any employer do sort lagvo, and
anther things is not safty of the instrumentation and
employer any bordy work of the instrumentation.

If a normal magnetic type flow transmitter that can measure flow, temperature and show this parameters on field, is it possible by any means to get this (flow and temperature) parameters info. On dcs? And if yes then with HART, FO communication or any other communication system?

HELLO FRENDS ,, I M IN THE MIDST OF TROUBLE .. JUST LITTLE HELP ME... SUPPOSE ,, I HAVE A CLOSE VESSELE TANK ( HEXANE MEDIA ) ,, I M USING ROSEMOUNT 2051 DPT FOR LEVEL APPLICATION .. ITS CALIBRATE RANGE IS.. . 0 TO 950 MMH20 ..I DID CALIBRATED DPT WITHOUT REMOVING IMPULSE LINE OF HIGH AND LOW TAPPING.. & WITHOUT DISTURB 3 WAY MANIFOLD..!!! BUT ,,, DURING CALIBRATION I SELECT RANGE BY HART LRV IS 900 MMH20 & URV IS 1300 MMH20 ,, BUT ,TANK LEVEL SOMETIMES 100 % AT 1100 MMH20 , SOMETIMES 1300 MMH20 ..IN THIS CONDITION .. WHOLE LOOP FAILED ,, MAIN THING IS THAT ,, HOW TO CUSTOME RANGE SELECT ?? AND IF I USED RANGE OVER THE ORIGINAL CALIBRATE RANGE ,,,THEN WHAT ERROR WILL BE COME ??? HOW TO ZERO CALIBRATION OF DPT... HOW TO ZERO TRIM BY MANIFOLD ?? AND FOR TANK LEVEL PURPOSE ... WHICH UNIT I CAN USE ??? IS THERE ANY CALCULATION OR CALIBRATION .. IF YEH .. THEN PLZ JUST GIVE ME CALIBRATION STEPS FOR DPT.. THANKS YOURSSSSSSS

If a control valve is hunting means means if we are giving 50% to the cv, the cv will open at 51% then slowly slwoly it will reaches 49% , so what to do for solve this problem. The cv is double acting and mounted for anti surge operation, it having 4 nos. volume booster, one sov, one positioner, etc..?
