PRESSOSTATO INVERSO
Aggiungete sicurezza al vostro impianto. In combinazione con il pressostato tradizionale, questo dispositivo permette di bloccare la pompa quando manca l’acqua. Si applica facilmente ai sistemi esistenti dotati di pressostato elettromeccanico monofase.

Caratteristiche
• Pressostato di protezione per impianti idraulici (sistemi autoclave, gruppi antincendio) e pneumatici (circuiti di comando in pressione).
• Il dispositivo interrompe il collegamento elettrico tra linea e carico quando la pressione scende al di sotto del valore impostato (pressione di stop).
• Nei sistemi autoclave viene impiegato in serie con un pressostato della serie PM/5 per proteggere l’elettropompa contro la marcia a secco.
• Il ripristino avviene in maniera automatica quando la pressione supera nuovamente il valore di start oppure per azione manuale sul tasto di reset.
• Doppio contatto elettrico normalmente aperto in lega di ottone con riporto Ag-Ni.
• Membrana in gomma NBR con inserto nylon.
• Pressacavi antistrappo.
OPTIONALS
• Numerose connessioni idrauliche disponibili.
• Tarature personalizzate.
• Versione dotata di cavi elettrici di collegamento per linea e motore.

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.
