Capabilities

The LEE Ventus 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 e.g. 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 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 configuration for use each time the Evaluation Kit is powered up, so that kit can be operated independently of the PC app without the need to configure over the serial interface.

Pressure cycling between two limits under bang-bang control.
