ARRANGEMENT AND METHOD FOR CONTINUOUSLY SUPPLYING ELECTRIC POWER TO A FIELD DEVICE IN A TECHNICAL SYSTEM

摘要

The invention relates to an arrangement for continuously supplying electric power to a field device (10), comprising a housing (11) in order to monitor a technical process in a technical system. Said field device is fitted with a wireless communication interface (5). The field device (10) comprises at least one field device side (11a) orientated towards the process and at least one field device side (11b, c, d) orientated away from the process and is fitted with a thermoelectric converter (14). Said converter comprises one converter side (14b) orientated towards the process (14b) and one converter side (14c) orientated away from the process (14c). The heat flow inside the field device between the field device side which is orientated towards the process (11a) and the field device side which is orientated away from the process (11b, c, d), is converted by the thermoelectric converter into electric power which can occur in a bi-directional manner.
