Answer / mohammad asfani

there is one formula with graphitical y=MX+b
for exma:Given a temperature transmitter with a measurement
range of -88 degrees to +145
degrees and a signal range of 4 to 20 milliamps, calculate
the proper signal output at an applied
temperature of +41 degrees.

Ans:take 41 deg and subtract to lrv mens -88. then 129 will
come and then you devide by span rang of transm..likespan
(145--88)=233,129/233=0.55 and take this number and
multiply by spanof current signal like 16ma and addto lrv
after that you can get ans...

as our Colleague said that is also right, but one more
simple way is that 1 mv is equal to 25 degree you can
calcutae bases on mv.nothing more
for ex 5 mv at element side then temp is 125 degree.

What are the error values can accepted in flow transmitter calibration?could u give any formula for this?
