SCHALTUNGSANORDNUNG FUER EINEN SENSOR.

摘要

An amplifier with temp. dependent gain is connected to the sensor output. The amplifier feeds an adder circuit which also receives a temp. dependent voltage. A differential amplifier (8) is used with a temp. dependent resistor (14) in its negative feedback path. The two connections forming the sensor output are connected to the inverting and non-inverting amplifier inputs. Adjustable resistors (12,13) are connected in series with the temp. dependent resistor and in parallel with these series resistances. These resistors form a T-element with a third variable resistor (11). The adder circuit is a further differential amplifier (16) receiving the amplifier output and temp. dependent and independent voltage inputs.
