Caratteristiche
• Serie di pressostati per applicazioni di controllo e supervisione in impianti tecnologici di diverso tipo (gruppi antincendio, macchine per l’edilizia, impianti per trattamento delle acque, ecc.).
• Il pressostato agisce meccanicamente per effetto della pressione nell’impianto e non necessita quindi di alcuna alimentazione elettrica ausiliaria.
• Contatto in scambio (COM.-N.O.-N.C.).
• Membrana: NBR con inserto tessile.
• Pressacavi antistrappo.
OPTIONALS
• Pulsante di esclusione temporanea per collaudo impianto secondo EN 12845 (10.7.5.3).
• Tarature personalizzate.
• Scala graduata per una facile regolazione.
• Grado di protezione IP55.

Features
• Series of pressure switches for control applications and supervision in different technological systems (fire fighting units, building machineries, systems for water treatment, etc).
• The pressure switch mechanically works per action of the pressure in the system and it doesn’t need any additional electrical power supply.
• SPDT contact (single pole double throw COM.-N.O.-N.C.).
• Membrane in NBR rubber with textile insert.
• Tear resistant cable clamps.
