When current is 0.099 mA, the temperature reading will be
Therefore, the error will be equal to 750°C - 742.5°C = 7.5°C
The error is negative as the reading will be less than the previous reading.
12.11 HALL EFFECT TRANSDUCERS
The principle of working of a Hall effect transducer is that when a strip of
conducting material carries current in the presence of the transverse magnetic
field, as shown in Fig. 12.14, an EMF will be induced between the opposite
edges of the conducting strip. The magnitude of-the voltage induced too will
depend upon the material of the strip, the current, and the magnetic field
strength. Thus, we can state that Hall effect refers to the potential
difference (Hall voltage) on the opposite sides of an electrical conductor
through which an electric current is flowing, created by a magnetic field
perpendicular to the current.
