The resistor values within the bridge are determined
by the desired sensitivity.
A silicon diode-connected transistor has a
temperature coefficient of about -2mV/°C. Calibration
is achieved by placing the sensing transistor in ice
water and adjusting the zeroing potentiometer for a
00.0 reading. The sensor should then be placed in
boiling water and the scale-factor potentiometer
adjusted for a 100.0 reading.
