BM 65 Plugged Chute Detection for Hazardous Locations

BM 65 Plugged Chute Detection for Hazardous Locations

The BinMaster plugged chute detector is a pressure switch that alerts when a chute becomes clogged by detecting pressure changes caused by buildup. This sensor is part of a family of switches used for blocked chute detection in handling systems. It has a heavy spring and rugged diaphragm for demanding environments, perfect for chutes carrying flowing grain, seed, feed or other granular or pelleted process material and bulk solids. The rugged diaphragm can withstand the abrasive nature and harsh environmental conditions found in industries such as mining, power generation, agriculture and construction where these detectors are used. The detector can be integrated with alerts to notify operators in time, ensuring safety and efficiency. When a chute is plugged, the device acts as a level switch, detecting and indicating a plugged condition at a specific point in the chute. It will sound an audible or visual alarm when attached to a horn, siren, light or alarm panel. The advanced technology used in the detector minimizes false alarms by distinguishing between actual blockages and coating, ensuring reliable operation and less maintenance. The design ensures it keeps flowing and blockages are addressed quickly, with a fast response time is critical for safety and efficiency. When selecting a detector, consider the size and the switch to ensure proper fit and function. The BinMaster detector is a product that can be added to a quote or order as part of your handling solution. It has UL Class II, Groups E, F & G explosion-proof certification and can be used in hazardous locations where combustible dust is present. It has simple, rugged construction and long lasting durability.

Mounting Options:

Choose from internal mount or external mount options. Internal mounting does not require a hole to be cut in the side of the bin but does require entering the bin for installation. External mounting requires a hole to be cut in the side of the bin but does not require entering the bin for installation.

Diaphragm:

Neoprene: .016” thick, black neoprene diaphragm. Neoprene is abrasion-resistant, chemical-resistant, waterproof and stretchable. Good for process temperatures from -30°F to 220°F and material bulk density from 15 to 60 lb./cu. ft. It’s wear resistance is good for abrasive process material.

Neoprene with Mesh: .020” thick, black neoprene with nylon mesh. This is the best diaphragm material to use in extremely high abrasive material. It has excellent resistance to most chemicals, heat and oils. Plus it’s flame resistant, has good color stability and weather resilience. Good for process temperatures from -30°F to 270°F and material bulk densities from 15 to 90 lb./cu. ft. The wear resistance of this material is good for harsh environments and abrasive solids.

Silicone: .031” thick, grey silicone diaphragm. Silicone has the best long term resistance to environmental extremes. The chemical, electrical and mechanical properties of silicone remain virtually unchanged in temperatures from -40°F to 350°F. Good for materials with bulk density from 15 to 60 lb./cu. ft. Its durability and wear resistance is good for various process material and environmental conditions.

Plugged chute detectors are an essential part of modern handling systems, designed to detect and alert operators to blockages in chutes, hoppers and conveyor transfer points. When material flow is interrupted by a plugged chute, the risk of equipment damage, downtime and inefficiencies increases dramatically. By using chute detectors, industries can detect and address these blockages before they become a problem and material can continue to flow through the system. This is especially important in industries such as coal processing, agriculture, mining and bulk handling where chutes and hoppers are used to transport grain, seed, feed and other bulk materials. Using plugged chute detectors not only prevents damage to chutes and related equipment but also minimizes the risk of unplanned stoppages, making them an essential tool for productivity and safety in harsh environments.

Features

Plugged chute detectors are designed to detect material flow interruptions in heavy duty applications. They come in different configurations, pressure switch and diaphragm switch, to suit different flow conditions. The rugged construction and diaphragm choices ensure reliable performance with abrasive or dense items. They sense pressure changes caused by the presence or absence and can detect a plugged chute and trigger alerts. Certified for hazardous locations with combustible dust, they meet UL Class II, Groups E, F & G explosion-proof standards and are suitable for industries where safety is critical. They can be mounted internal or external on chutes and hoppers for flexibility in installation. Whether it’s grain, feed or other heavy items, these chute detectors are the solution for detection in tough environments.

How it Works

Plugged chute detectors work by continuously monitoring the flow of material through chutes, hoppers or pipes using a sensitive sensing element, usually a diaphragm. As material flows normally, the pressure on the diaphragm is within a set range. When a blockage occurs and material starts to build up, the pressure on the sensing element changes and triggers the pressure switch. This sends a signal to an alarm panel which can activate a horn, siren, light or other alarm to notify the operator of the plugged condition. This immediate alert allows the operator to respond quickly and minimize equipment damage and downtime. It’s suitable for use with various materials such as grain, seed, feed, coal, powders and other granular substances. By detecting both the presence and absence of material flow, these detectors ensure chutes are clear and operational and support efficient and safe material handling across multiple industries.
