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.

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
(click here to download)
 

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

 

 
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.

 

 
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 diaphragm provides corrosion resistance when used with corrosive materials or added protection in abrasive applications.

 

 
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.

 

 
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.

QuantiMassTM
Mass Flow Measurement Systems
The QuantiMass in-line mass flow sensor measures the flow of quantities in pneumatic conveying & free-falling processes. The sensor is based on the latest Microwave Doppler Effect technology and provides fast, in-line / on-line measuring without the use of weight scales.
The sturdy, non-intrusive design of the sensor minimizes maintenance. In addition, the compact size of the sensor makes for easy installation into existing processes. Suitable for powders, dust, pellets, and granular up to 0.75 inch (2cm).

Versions:
Ultra Series-Includes controller
PRO Series-Includes transmitter

A practical application for the QuantiMass would be to monitor material flow rates to verify blending mixture ratios.

Principle of Operation:
The QuantiMass Mass Flow Measurement Sensor / Meter is designed with the latest microwave technology and is used to continuously quantify the flow of powders & solids being conveyed in metallic pipes. The QuantiMass is based on technology that has been developed and proven by Muetec Intruments over several years. The measurement process of the sensor is centered on the Doppler effect. The mass flow-rate is determined by evaluating the frequency and amplitude changes during the measurement process. Particles at rest, such as deposits, do not influence the measurement. All powders, dust, pellets and granules can be measured reproducibly, up to the size of 0.75 inch (2cm). The QuantiMass sensor is suitable for continuous in-line / on-line measurements in pneumatic conveying or in free-fall pipelines.
