Disc Pump Capabilities

The Disc Pump Control App is packed with features and offers flexible configuration and control of the Evaluation Kit.

Three control modes:
- Open-loop control of pump drive power.
- Closed-loop control of pressure or vacuum, enabling a wide range of applications out of the box (e.g. inkjet meniscus pressure control and ‘pressure-driven flow’ microfluidics). Alternatively, connect your own sensor for PID control of other variables.
- “Bang-bang” pressure/vacuum control, enabling cyclic pressure control as used in intermittent compression therapy.
Analog control sources can be mapped with range and offset variables, enabling fine-tune control over the set point. The analog control sources include:
- A physical potentiometer/dial on the Evaluation Kit motherboard, providing a quick-to-adjust setpoint control.
- A 0-2.5 V analog input, enabling connection with a control signal or pressure/flow external sensor.
Configurable live graph display of pressure, power, and other electrical parameters.
Datalogging to CSV file of pressure, power, and other parameters.
Ability to save the configuration for use each time the Evaluation Kit is powered up, so that the kit can be operated independently of the PC app without the need to configure over the serial interface.

The Lee Company also offers drive electronics for applications beyond the initial pump testing phase. For more information on driver options, please visit our Drive Electronics and Accessories page.

The Evaluation Kit User Guide provides a detailed overview of the kit, outlining the system components, safety considerations, system operation and support.

PIEZOELECTRIC DISC PUMP EVALUATION KIT USER MANUAL

The Disc Pump Control App provides configuration, control and data logging for the Evaluation Kit.

Disc Pump Control App

Our GitHub code snippet library provides examples of how to control the Disc Pump Evaluation Kit independently of the Disc Pump Control App. The initial examples provided cover a range of functions, including turning the pump on and off, setting drive power, closed loop control of pressure and reading back and plotting data.

The code snippet library, which is hosted on GitHub, is intended to support customers after their initial evaluation of our pump technology, as they move on to developing prototypes and products. We welcome suggestions for how we can improve and build upon this repository; please feel free to share your ideas, feature requests and any bugs you identify with us.
