Description
This new vacuum pump system now supports remote control over a portable hand terminal.
A pressure sensor measures the actual pressure in the system several times per second, and a microprocessor monitors any pressure drop over time. The pump speed is adapted according to this information constantly.
Four operating modes of the vacuum pump system
- Evacuate: the vacuum pump system evacuates a vacuum chamber with adjustable pump capacity.
- Pressure control: the vacuum pump system controls the system pressure to the set value (constant pressure).
- Automatic: the vacuum pump system automatically finds the vapor pressure of the sample and adjusts the process pressure accordingly.
- Individual pressure profile: the vacuum pump system controls the process according to a user-defined pressure curve. The setpoint pressure and the opening and closing of the coolant valve (accessory) on the high-performance condenser can be easily entered for a range of set times. A repeat function allows successive repetitions of the programmed pressure curve.
