1. Homework Statement
A 4-20mA current loop is being used to transfer temperature
values in the range + 10ºC to +60ºC.
(i) What temperature is represented by a current of 7mA?
(A) What current would you expect when the temperature of the
sensor is 32ºC?
i HAD AN ATTEMPT, CAN U TELL ME IF ITS RIGHT. I AM REALLY STRESSED OVER THIS QUESTION. THIS IS MY 3RD ATTEMPT. tHANKS FOLKS
20-4 =16mA
60-10= 50 DEGRESS
50/16=3.125
(A)
7mA-
3.125=X/7
X=21.88 DEGREES
(B)
32 DEGREES-
3.125=32/X
X=32/3.125
=10.24A
