Patent number: 12241566Abstract: An adapter for wireless data transmission, in particular according to the “Bluetooth Low Energy” standard, is proposed. The adapter has a cylindrical housing whose radius is at least twice its height. The adapter includes a wireless transceiver and a processor arranged in the cylindrical housing and connected to the wireless transceiver, and a data interface connected to the processor. The processor is arranged to drive the transceiver and the data interface and can therewith transmit data wirelessly. Because the adapter for wireless data transmission has a flat design, it can be retrofitted in valve positioners. This makes it possible to retrofit commonly used valve positioners that until now do not have an option for wireless transmission of their status data with this adapter. As a result, these commonly used valve positioners also achieve the capability of wireless transmission of their status data.Type: GrantFiled: March 16, 2021Date of Patent: March 4, 2025Assignee: SAMSON AKTIENGESELLSCHAFTInventors: Leonard Yousif, Melanie Dürr, Andreas Klein, Christian Mellinger
