The trend in life sciences is towards ever smaller medical devices. This is especially true in mobile applications such as portable oxygen system devices, the emphasis is on minimal power consumption and low weight. This is coupled with high standards for reliability and performance. A key technology that offers decisive advantages here is piezo technology as it is surprisingly cost-efficient.
The gas flow at the output of the mass flow controller can be adjusted very simply and controlled in linear mode by entering a setpoint between 0.2 and 10 V.
The integrated control loop with thermal sensor makes the VEMD precise and dynamic. It reacts very quickly to a setpoint change and is practically ready for operation instantly.
The VEMD is distinguished by it compact installation dimensions. Its lightweight design makes it ideal for installation in portable devices.
Thanks to the piezo technology, no pulse-width-modulated signal is required to control the flow rates, which means that the proportional flow control valve VEMD operates silently.
