A silicon diode-connected transistor has a temperature coefficient of about -2mV/
o
C. Calibration
is achieved by placing the sensing transistor in ice water and adjusting the zeroing potentiome-
ter for a 000.0 reading. The sensor should then be placed in boiling water and the scale-factor
potentiometer adjusted for a 100.0 reading. See AD590 data sheets for alternative circuits.
