Development of a low-cost, hand-held, remote vacuum profile monitoring system

Vacuum technology is a very widespread area. Nowadays, a broad variety of applications can be found to be using vacuum and vacuum related monitoring. Vacuum profile for different applications can be different, but whatever that may be, monitoring it is an essential part of any such application. Thus, this paper describes the development of one such vacuum profile monitoring system that can be re-purposed to be used in testing a wide range of systems. The main aim is to develop a device that is low cost, app-based and precise with a very small form-factor such that it can be hand-held for greater portability and ease-of-use. The intention here is to develop a generic device which can be used in any vacuum monitoring application, hence, the focus will not be on any specific application, but instead, in this paper, the focus will be on the development of the device itself.
