Pressure Switch АТЕХ
ATEX/IECEx certified relays for zones 1, 2, 21, 22 and mining applications, for monitoring gas, dust and liquid pressure.
Suco ATEX explosion-proof pressure switches are a professional solution for use in potentially explosive atmospheres. Designed for gases, dust, and liquids, available in diaphragm and piston versions, they provide accurate pressure control and comply with
Suco ATEX explosion-proof pressure switches are specialized devices for use in potentially explosive atmospheres, certified in accordance with ATEX 2014/34/EU, and models in the 0342 / 0343 series are also certified in accordance with IECEx.
Key Features
Variety of designs: diaphragm and piston versions available for different operating conditions.
Contact types: normally open (NO) or normally closed (NC) — for flexible system configuration.
Precise adjustment: easy adjustment of the operating point, factory calibration possible. Adjustable hysteresis: 10-30%.
Versatile application: suitable for liquids, gases, air, and water.
Contact protection: special covers prevent dust and moisture from entering.
Operational stability: high accuracy and reliability even after prolonged use.
Compliance with standards: ATEX/IECEx certification (Zones 1 + 2 (gas), 21 + 22 (dust), Category M2 (mining industry)).
