The PENTEK INTELLIDRIVE is specifically designed to
operate 4” submersible pumps. Each drive is rated for
maximum output amp rating. Any use of the drive
outside of its intended use and design parameters will
void the warranty.
Transducer
The drive uses a 4-20mA, 0-690 kPa pressure transducer to
control the speed of the motor.
The transducer senses pressure in the pipe and converts it
to an electrical signal which it sends to the drive. The drive
processes the signal in the PID (Proportional, Integration,
Derivative) control. When operating in PID mode the drive
increases and decreases the speed of the pump motor as
needed to maintain constant pressure in the system.
