VEL-trol II Transmitter
The VEL-trol II transmitter-controller is furnished with an automatic zeroing circuit capable of electronically adjusting the transmitter zero at predetermined time intervals while simultaneously holding the transmitter output signal. The VEL-trol II incorporates the three control modes of proportional, integral reset, and inverse derivative. This feature permits the controller action to be tuned to the extreme dynamics of the airflow or pressurization control process.
