Field device of the pressure-resistant encapsulation type of protection |
摘要 |
The present invention is directed to an electrical field device of the pressure-resistant encapsulation type of protection for use in areas at risk of explosion and has at least a first and second mechanically and electrically coupled modules. The first module includes a connection space for the connection of the field device in an explosion-hazard area with safety barrier arranged therein and has a housing of the type of protection of the pressure-resistant encapsulation. The second module includes a field device of the self-secured type of protection and the electrical connection between the two modules comprises an arc-over-proof lead bushing, and the electrical signal connections of the second module are realized via the lead bushing.
