Caratteristiche
• Pressostati di sicurezza omologati PED per l’impiego in impianti di riscaldamento.
• I dispositivi arrestano automaticamente il generatore di calore al raggiungimento di un prefissato limite di pressione dell’acqua.
• Il ripristino avviene esclusivamente per azione manuale sul tasto di reset dopo che la pressione è rientrata di almeno 0,4 bar entro il valore di blocco.
• Scala graduata visibile dall’esterno.
• Doppio contatto elettrico normalmente chiuso (PMR5) o normalmente aperto (LPR5) in lega di ottone con riporto Ag-Ni.
• Membrana EPDM nera con inserto in PA (nylon).
• Pressacavi antistrappo.

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.
