Our customer uses the ZUMO-ALD for
simultaneous control of up to 10 microfluidic pumps. The system also records
the temperatures of up to 4 type K thermocouples.
The pumps each have a separate housing, so they
can be positioned directly and space efficiently in a fume cupboard. The pumps
and the thermocouples are controlled by a U-Remote system from Weidmüller. The
remote I / O system and the electronic speed controller of the pumps are
located in a control cabinet which is set up outside the fume cupboard. The
software of the ZUMO-ALD was developed in the programming environment LabVIEW
by National Instruments. It enables the user to operate in two modes, manual
and automatic. In manual operation, the pump flows can be adjusted manually and
the temperatures can be read. In automatic mode, sequence controls for
controlling the pumps can be created, loaded, saved and executed. All input and
output data can be saved in both operating modes. The various parameters of the
U-Remote system can be adjusted in the settings menu of the software, and the
number of sensors and actuators can be adjusted at the customer’s request.
Additional functions such as pressure measurements or temperature controls can
also be integrated into the system.
