The temperature measurement and analog-to-digital conversion circuitry, as well as the calibration tables, are located in the blackbody head.
This new architecture eliminates the system’s sensitivity to noise, enhancing blackbody stability and accuracy.
The calibration of the blackbody head is independent of the controller, so heads and controllers can be swapped without recalibration. The microprocessor-based temperature controller is designed for optimum accuracy and stability. A high resolution enhanced PID temperature servo provides zero drift and low jitter setpoint control.
