The new pressure housing (protection classification: Ex d) can be used for all applications utilising a power supply to the sensors which is not intrinsically safe.

An integrated zener barrier allows the connection of sensors — protection classification Ex ia / ib — in the ex zone directly to the pressure housing. In addition, the pressure housing can be equipped with a digital display. The display can be adjusted individually to face a number of directions, facilitating its reading.The octal input module VISY-Input 8, installed in a splash proof case links external alarm outputs and the tank level gauge VISY-X. This allows the indication of alarms from different systems at one central point. The connection to VISY-X is done by a simple communication line.
