The Atex pressure switch from Juices are all compact, robust and durable. At the Hanover Fair, the company is presenting the new SW 27 series pressure switches of the 0342/0343 series Atex Directive 2014/34 / EU and IECEx scheme for electrical explosion-proof equipment certified. With installation dimensions of around 50 mm, the pressure switches are among the most compact Ex pressure switches in their class.
The new pressure switches combine the advantages of the established types 0165 (SW 30) and 0340/0341 (SW 27). The pressure switches are for you Use in the following Ex zones designed:
- Gases and vapors: Zones 1 + 2 (II 2G Ex db IIC T6 / T5 Gb)
- Dusts: Zones 21 + 22 (II 2D Ex tb IIIC T80 ° C / T100 ° C Db)
- Methane and coal dust (I M2 Ex db I Mb)
Pressure switch with type of protection Ex d
The pressure switch series 0342/0343 was used in relation to the Ignition gap dimensions redesigned to cover the gas area zones 1 + 2 according to DIN EN 60079-1. This created a type of protection ex d Flameproof enclosure achieved, which guarantees the inclusion of potentially occurring ignitions or explosions inside the switch housing.
Also the type of protection Ext Protection by housing is given. This ensures an intrinsically safe circuit in the entire pressure switch (see Ex i). The general level of protection is increased many times over within an explosive atmosphere.
The Atex pressure switch is suitable for Voltages up to 250 V. and has protective insulation of protection class 2. The switching point can be set using an adjusting screw when installed.
Energy-efficient vacuum pump, suction cups, sensors & Co.
The Diaphragm design Type 0342 is available with six-fold overpressure safety up to 300 bar in four variable pressure ranges from 0,3 bar to 50 bar. The piston version type 0343 withstands static pressure up to a maximum of 50 bar in the pressure range 150 bar to 600 bar.
In order to avoid possible sources of error when connecting the contacts within the Ex area, both pressure switches are fully wired and encapsulated. In IP65 they are made available in standard cable lengths of 2 m or 5 m.
Applications in all Atex areas and zones
Due to the successful approvals according to Atex and IECEx system of the device categories Gas II 2G, Dust II 2D and Mining I M2, the new pressure switches are suitable for almost all Atex areas and zones. Such can be found in the process industry such as oil and gas, chemicals, petrochemicals, pharmaceuticals as well Food industry, Sugar production, pulp production, paper industry, wood industry and steel industry.
Smart domestic waterworks also for outdoor applications
Further branches the pressure switch are Medical Technology, Energy, paints and Surface Technology, disposal and recycling, bulk goods and conveyor technology as well as heating, ventilation and refrigeration technology (HVAC).
