Type S Thermocouple Amplifier with Ultralow Offset and Drift
THIS AMPLIFIER HAS A DELIBERATE OFFSET TO ALLOW OUTPUT SLOPE (10mV/ C) TO BE SET
INDEPENDENTLY FROM AN ARBITRARY HIGH TEMPERATURE CENTER POINT (1000 C). THIS IS
REQUIRED BECAUSE THE SLOPE OF TYPE “S” THERMOCOUPLES VARIES RAPIDLY WITH
TEMPERATURE, INCREASING FROM 6 V/ C AT 25 C to 11 V/ C AT 1000 C. NONLINEARITY LIMITS
ACCURACY TO 3 C OVER THE 800 C TO 1200 C RANGE EVEN WITH OFFSET CORRECTION
