Filter with data storage provided with an antenna for transmitting signals

Abstract

The invention relates to a filter element (1) for filtering fluids, such as hydraulic fluids or gases, the filter element (1) being accommodatable in a filter housing (12), having an inlet point (18) for the fluid to be filtered and an outlet point (20) for the filtered fluid, the filter element (1) comprising a data storage (52), data stored in the data storage (52) being electronically readable from the data storage (52) by means of a read and / or write device (70), characterized in that an antenna (60) extending outside the data storage (52) is provided for the signal coupling between the data storage (52) and the read and / or write device (70), and that the antenna (60) extends at least in sections about a longitudinal axis (44) of the filter element (1) and thus, independently from the angular position of the filter element (1) and the data storage (52) attached thereto, a signal coupling between the data storage (52) and the read and / or write device (70) is ensured. The invention further relates to a filter device (10) having such a filter element (1).

Description

technical field [0001] The invention relates to a filter element for filtering fluids, such as hydraulic liquids or gases, and to a filter device equipped with such a filter element. Background technique [0002] For the filtration of liquid, gaseous or pasty media, such as hydraulic media, process fluids or even food such as beverages, filter elements suitable for the relevant application are used. These filter elements differ in many parameters, such as the material used for the filter substance, their pore size or pressure stability. These different features are in many cases not, or not at all, readily discernible. [0003] In principle, therefore, there is the danger that an unsuitable or unsuitable filter element may be fitted to an existing filter device, which could cause damage to the filter device, to the medium to be filtered or to the connections. damage to the system on the filter unit. As a result, for example, in the case of insufficient filtration, wear ca...

Problems solved by technology

Furthermore, contamination of the filtered fluid due to the incorporation of harmful substances due to the use of unsuitable filter elements

In addition, it cannot be ruled out that when replacing a spent filter element, it is forgotten to insert a new filter element into the associated filter housing and unintentionally connects the empty filter housing to the on the filter

[0004] Another problem may arise from the fact that it is difficult to detect how long a filter element will maintain adequate filtration under a given operating condition when a filter element is in use

This is the case in particular when using certain filter element types which do not have a continuously decreasing filter performance, but instead have a sudden drop in filter performance after an operating time which is relevant to the mode of operation in question
