The present invention relates to transducer housing and a tool for opening and closing the transducer housing (20). The transducer housing comprises a base body (22) and a lid (24) which are releasable coupled with a rotational coupling (26). The lid (24) comprises a contact area (42) formed to be engaged by a driving pin (64) of the tool (10) in order to open or close the transducer housing (20) upon a rotation of the lid (24) relative to the base body (22). The tool (10) comprises a base portion (12) and an upper portion (14) that are coupleable wherein the upper portion can be rotated relative to the base portion. When coupled the upper portion and base portion may enclose the transducer housing such that upon a rotational movement of the upper portion (14) relative to the base portion (12) the driving pin (64) of the upper portion (14) engages with the contact area (42) of the lid (24) causing the lid (24) of the transducer housing (20) to move relative to the base body (22) of the transducer housing (20) resulting in an opening or closing of the transducer housing.
