The past decade has seen significant advancement in the field of mobile devices. Various smart devices such as cellular phones, tablets and PDAs have become universal tools in our everyday lives. Their versatility is based on their computing power, portability and their integration with other devices and services such as the World Wide Web. However, these smart devices have an even wider usability spectrum. They can also be used for wireless industrial measurements using existing sensors. The wireless connectivity of existing industrial sensors is achieved by equipping them with a Bluetooth module, which digitizes the data and passes it to any Bluetooth capable smart device for further processing, evaluation and logging. This paper describes the specially designed Bluetooth platform for wireless measurements all the way from the basic concept, through hardware, firmware and software implementation, to the sample tests and measurements.

Almost all projects nowadays are fast paced as all industries are trying to shorten time to market and hydraulics is no exception. In order to compete in such environments all the processes in the company from engineering throughout production have to be streamlined, so they are able to effectively follow the ever-changing project requirements. Moreover, increasing lead-times and disrupted supply chains due to pandemic also influence the workflow, as components may not arrive in time. This article addresses all of the above-mentioned problems on a real world hydraulic project – a hydraulic drive of a forklift. It presents the evolution of hydraulic schematic, hydraulic manifold and control algorithms all the way from the first draft to the latest version.
