Monitor’s line of BINATROL® diaphragm bin level switches consists of economical, reliable, and durable point level controls for point level detection of dry bulk materials like grain, pellets, cement, regrind and much more. 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.
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 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. Provides good performance in solids from 10 - 60 lbs/ft3. These products are not normally used with materials which are very light, sticky or of large particle size.

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.
The Model GX-SS BINATROL® unit has a stainless steel diaphragm material.
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.

Accessories
HYCAR® COVER
Monitor offers a HYCAR® (oil resistant) cover for the diaphragm for watertight applications and to provide additional abrasion resistance. This cover is typically used with Models G and GX.
