the elements necessary for the electrical connection (connector and cable, 3). The Ex d Type
0813 angle sensor is always equipped with a threaded pin (4) for electrical potential equali-
sation (this is optional in the other types). Base plate and housing are made from an alumini-
um alloy as standard; stainless steel is available as an option.
Figure 2 shows the typical installation conditions:

The angle sensor (1) is usually fixed at the installation site to the appropriately designed
seatings (2) using securing elements (3). The normal to the measuring plane (4) is perpen-
dicular to the direction of gravity (5). The measurement electronics measure the angular po-
sition (6) of the angle sensor in the measuring plane and output this as an electrical signal.
Versions with two measuring systems, either with output signals on separate connect-
ors/cables or combined in one connector/cable, are available as options. More information
can be found in the technical data sheets, which can be obtained free of charge from
BROSA.
1.2 Information on explosion protection
The Ex d type 0813 angle sensor is encapsulated as pressure-resistant and thus suitable for
use in potentially explosive atmospheres. The following specifications apply:
