Explosionproof sealing boxes and sealing sphere

Purpose

Explosionproof sealing box and sphere are designed to accommodate a video camera, microwave movement sensor, light sensor or other equipment. For arrangement in premises, in which there can be explosive gases or dust, according to explosion protection marking.

Features

• The sealing box and sphere enable to install various equipment inside requiring availability of monitoring thereof or monitoring of external objects.
• The sealing box is primarily adapted for arrangement of a video camera.
• The sealing sphere, having a light transmitting element in the form of a hemisphere, is intended for equipment requiring a wide angle of visibility or wide beam angle for its operation.

Design

The sealing box consists of an aluminum body with powder coating, which forms an explosionproof enclosure with “d” type explosion protection.

The protective light transmitting element is made of borosilicate glass, extra strong, with high light transmitting capability integrated into the cover.

The sealing sphere consists of an aluminum body with powder coating, which forms an explosionproof enclosure with explosion protection type

The protective light transmitting element is made of polycarbonate, extra strong, with high light transmitting capability, screwed into the sealed sphere.

Cable is laid through side entries. The bracket attached to the sealing sphere body is used for assembly. Transit cable laying is provided additionally.
