TTP Ventus offers a Disc Pump Evaluation Kit (see our products page) containing everything that you need to get up and running. The Evaluation Kit is suitable for laboratory testing, proof-of-concept and product prototyping, and enables control of the pump output in a variety of ways to suit your application. These are configurable using a PC application provided with the Evaluation Kit.
Constant Power Control
Disc Pump is driven at constant electrical power. This setting is recommended for general use.
Constant Pressure Control
With its onboard pressure sensor connected to the pneumatic system, the drive PCB adjusts the Disc Pump power to maintain a target pressure set-point. In most applications, pressure can be held with a precision better than ±0.1 mbar without the need for dampers, baffles or accumulators. Note that in pressure control mode the maximum power is limited by the PCB, meaning that only target pressures within the normal operating range can be achieved.
Analogue Power Control
Disc Pump power is controlled via a 0-3 VDC analogue input to the drive PCB, which maps to 0 - 100% power output. This mode is useful where the pump is being used as part of a closed-loop control system -- for example, where integrated with your own development platform.
As an alternative to using the PC application software provided with the Evaluation Kit, you can connect to the drive PCB using a serial link and send commands directly to the drive PCB from your own software.
