Laptop-assisted Helium Liquefier: software for tailored monitoring and   control
  Computer running human machine interfaces are fast supplanting conventional hardware dedicated to monitoring and supervising tasks. This kind of approach was successfully employed to develop a new monitoring and control software, running on a conventional laptop computer, for a small size helium liquefier. This software was realized with a SCADA development package and hallowed to manage all the liquefier functionalities. Being conceived as an open structure suitable for further upgrades, this liquefier HMI can be tailored on demand to satisfy specific needs of the end-user, even if not provided by the original manufacturer project.
