BINATROL® Diaphragm Style Bin Level Monitor
-------------------
Manufacturer: Monitortech(USA)
Model: G/GX/GX-SS Series
Introduction:
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.
Features:
SIMPLE DESIGN
The simple design of BINATROL® diaphragm pressure switch / bin monitor provides for maximum ease of use. The BINATROL operates using a "floating" diaphragm, which is free of the electric switch mechanism. Diaphragm movement as little as 1/32" (0.8mm) triggers the unit. Also, the BINATROL pressure switch has no driven parts and thus requires no auxiliary power source. These design features ensure reliable and durable, low maintenance operation.
ADJUSTABLE SENSITIVITY
The BINATROL® offers a sensitivity adjustment that is accessible from outside of the bin and easily adjusted with a screwdriver. This enables the user to adjust the sensitivity of the unit, should vessel contents change, without removing the unit from the vessel.
LOW PROFILE MOUNTING
The low profile mounting of the BINATROL® unit eliminates major protrusions into the bin. This minimizes obstruction of the material flow in the vessel or chute. Also, the beveled-edge construction eliminates any possibility of material lodging.
OVERPRESSURE PROTECTION
The BINATROL® diaphragm din monitor incorporates a unique sensing plate which provides for overpressure protection. This feature prevents damage to the unit due to heavy loads or forces. In the event that a heavy load is applied to the sensing plate, a mechanical stop prohibits the plate from exerting excessive pressure on the sensitivity spring.
EXTERNAL INSTALLATION / MAINTENANCE
One of the biggest assets of the BINATROL® diaphragm bin monitor is the ability to install and maintain the unit from outside of the vessel. All parts, including the diaphragm are accessible from outside of the bin, without removing the mounting flange. This enables the user to install the unit, change diaphragms and perform basic maintenance without removing the entire unit. For applications which require installation from within the bin, this can also be easily accomplished.
Model
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 diaphragm provides corrosion resistance when used with corrosive materials or added protection in abrasive applications.
