SM85 Level Control

The SM85 is a simple and economical instrument suitable for the minimum and maximum level control inside silos or hoppers that contain no sticky mate- rials, powders or granulars like rice, corns, plastics, coffee, sand, lime, etc.

Working is very simple: the pressure practiced by material on membrane activates a trigger.Trigger sensibility is adjustable by a screw placed on the instru- ment tap. Humidity and temperature variations do not affect working, the membrane is collision and vibration proof.The mounting is external on the silo’s wall by the means of 3 holes placed on the fixing flange.

SM85 for the control of the level of powders or granulars in absence of fuel dust.

SM85.ATEX for the level control of materials, where, inside (process zone 20) or outside the tanks (Environment zone 21) a potentially explosive atmosphere, like dust cloud, can be present.

The installation of SM85.ATEX has to be compulsory coupled to an inherent safety barrier in order to carry out a suitable separation between the safety zone and dangerous zone.
