Setpoint Controller PXR4

Setpoint Controller

 

The Fuji Electric Model PXR4 Set Point Controller is one of the most technically advanced instruments in the industrial and commercial markets today. It is also one of the least expensive controllers of its kind. Through the use of a specially designed Fuji microprocessor, the Model PXR4 incorporates the latest technology for controlling applications. With simple, finger-tip programming from the front panel, the operator can tailor the operation of the controller quickly and easily. By automatically setting proportional band, integral (reset) time, and derivative (rate) time by means of the autotuning function, control parameter guesswork is eliminated. In addition, this controller employs Fuji's patented fuzzy logic algorithms. The Model PXR4 can learn processes, using the PID parameters as a starting point. This intelligence allows your process to reach its set point in the shortest time possible while virtually eliminating overshoot.
