Measuring principle

A diaphragm bin monitor provides level indication by detecting pressure applied by the bulk material to the sensing diaphragm. The unit is installed to a vessel wall so that the diaphragm is exposed to the material to be sensed. As material contacts the diaphragm, a force is exerted through the diaphragm to a pressure plate within the bin monitor. Physical deflection of the pressure plate activates an internal switch which is user accessible for signaling alarms, lights or PLC inputs. When material recedes from the diaphragm, a light duty spring returns the pressure plate and internal switch back to their original positions.

Application guidelines

The BINATROL diaphragm pressure switches / bin monitors can be used to detect high, low and intermediate product levels on dry material storage bins. The BINATROL can be used on either flat or curved surfaces. For bins with a diameter greater than 12' (3.6m), extra gaskets are not required. For certain applications, the BINATROL can also be used to detect plugged or backed-up conveyor chutes. Depending on the selected options and accessories, these units can be used with light powders, granules, materials with varying particle sizes, pellets, and abrasive and corrosive materials. These products are not normally used with materials which are very light, sticky or of large particle size.

Typical Applications include, but are not limited to:
Grain
Wood Chips
Chemicals
Powders
Regrind
Cement
Feed Pellets
Sawdust
Resin
