Bamo SNR 4 Level Controller

Bamo SNR 4 Level Controller rising in the tube (open at the bottom), make the pressure increasing inside the measuring tube. The pressure variation acts on a diaphragm that directly activates a contact. The level controller SNR 4, affords a dirt liquid as far as this one does not clog the measuring tube. Thresholds are adjustable.

NOTE: The inner atmosphere can diffuse through the diaphragm; It is necessary to renew the atmosphere (fresh air) every three months
