Abstract

The unit (10) has a high-security outer housing (13). A first section (11) of the latter accommodates the inserted operating battery, contained in a high-security sand-filled housing together with switch-gear restricting the battery current to an inherently safe level. A pressure-resistant encapsulated switch is actuated by the battery housing when this is inserted or removed. This cuts the separated from the first bY a wall, contains the detection, processing and indicating equipment, and is likewise sand-encapsulated. Pressure-resistant wiring between the sections passes through the wall.
