Monitor Binatrol Diaphragm Switch

Monitor's line of BINATROL® diaphragm bin monitors consists of economical, reliable, and durable point level controls for point level detection of dry bulk materials. The units can be used to eliminate bin overflow, maintain a predetermined material level, indicate plugging of chutes or conveyors or provide any of a number of level control functions. The flush mount, non-intrusive BINATROL units are ideally used when vessel size or internal clearance is limited, or where protrusion into a vessel is not acceptable. All installation and servicing, including diaphragm replacement and sensitivity adjustment, can be done from outside the vessel. These products are not normally used with materials which are very light, sticky or of large particle size.

Monitor offers a variety of diaphragm bin monitors that can be configured with various switch sensitivities, diaphragm materials and approval ratings.

Principle of Operation:
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.

Applications:
The BINATROL® diaphragm 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' extra gasket materials 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.

Models:
MODEL G
The Model G is the most basic BINATROL® diaphragm bin monitor. It provides accurate point level control on most bin types for products ranging from pellets to fine powders.

MODEL GX
The Model GX offers all the features of the Model G, but is specially designed to provide dust-ignition proof protection. This model should be used in applications which require Class II dust-ignition proof approval.

MODEL GX-SS
The Model GX-SS is the dust- ignition proof version of the Model G with a type 321 stainless steel diaphragm. This type of diaphragm provides corrosion resistance when used with corrosive materials such as fertilizer or added protection in abrasive applications. All other features are consistent with Models G and GX.

Options:
DIAPHRAGM MATERIALS
The Model G and GX BINATROL® units are available with two different diaphragm materials.

Standard Diaphragm: The standard diaphragm is constructed of neoprene and is compatible with most basic applications.

Teflon® Diaphragm: A Teflon® diaphragm is available for use in high-temp applications. This diaphragm can also be effectively used in sticky applications.

ULTRA-SENSITIVE SWITCH
The Model G, GX and GX-SS units come with a standard SPDT switch. However, for applications involving lightweight materials, Models G and GX can be specified with an ultra-sensitive switch.
