Proportional Pump Controller
( 1 items )
This system uses a Partlow controlled variable
frequency drive to run a centrifugal pump proportionally. It uses an
ultrasonic level sensor to determine how much water is in the initial
holding tank. As the water level increases and decreases with usage,
the controller alters the pump speed to maintain a steady water level.
Suitable for any application where a constant speed pump is not
practical, or to save wear and tear from constant on/off operation.

Custom Process Controllers
( 1 items )
The Partlow 116x series control modules can take inputs from RTD's, linear mV, thermocouples, liner DC mA and linear DC volts. With these versatile input capabilities, they can read practically any transducer, transmitter or sensor. The display can use custom units between -1999 and +9999 with up to three decimal places, so they can display the range of practically any sensor.
Outputs can be set to relay, SSR, 0-10 V DC, 0-20 mA DC, 0-5 V DC or 4-20 mA DC. This allows them to drive practically any actuator or retransmit to a wide range of drives.
The result is a truly versatile unit for process control.
