SECTION 8: Pentek Intellidrive
Transducer
The uses a 4-20mA, 0-100PSI
Pentek Intellidrive
pressure transducer to control motor speed (max
is 300 PSI transducer).
The transducer (see Figure 1) senses pressure
in the pipe and converts it to an electrical signal.
The Drive senses and processes the signal in the
PID (Proportional, Integration, Derivative) control.
When operating in AUTOSTART mode, the Drive
increases and decreases the speed of the pump
motor as needed to maintain constant pressure in
the piping system.
Changes internal pressure setpoint
from 15 PSI to transducer max -3PSI
(default is 60
Runs the Drive at 45Hz (with no
pressure control) to allow installer to
pump out well.
