RT-E

Pressure switches for explosive areas

The RT-E series consist of pressure and differential pressure switches . The units are designed for industrial refrigeration and general industrial application in explosive zones according to 94/9/EC, Atex directive, explosive zone 1, for surface equipment, category 2. . RT-E pressure  switches for use in explosive zones incorporate SPDT changeover switch where contact positiondepends on pressure value of the system

DESIGNED FO USE IN EXPLOSIVE ZONE 1
VERSIONS WITH ENCLOSURE IP 66
METALLISED FRON COVER WITHOUT WINDOW
GOLD PLATED CONTACTS

APPROVALS:         Ex II 2G Ex IA IIC T6 Gb 
                                 CE marked according to EN 60947-4/-5

ELECTRICAL CONNECTION:
The RT-E pressure control placed in explosive zone must always be wired through reliable zener barrier, placed outside ex-zone, to ensure insufficient energy supply to cause the ignitionof surrounding atmosphere by an electrical spark or the heating of components of circuitry  The equipment to be used for electrical load limiting must always be approved for use in the zone concerned 

Cables and cable entries approved for the application must be used and can not be incontact with sharp edges. Cables must be connected with adequate stress relief that way that pulling forces can not be carried throug the cable to the terminal.

Note:

A particular system can be classified in different zones, for different parts of the system
