PMA12 PTA12
PRESSOSTATI PER COMPRESSORI D'ARIA
Non solo acqua. Questa famiglia di pressostati è la soluzione ideale per la gestione di un compressore. Dotati di valvola di scarico automatica sono in grado di evacuare l’aria dal cilindro del compressore per un elevato numero di ciclo di stop, garantendone il corretto riavvio al ciclo seguente.

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.
