BM-45 Diaphragm Switch

Listen to this article

Proven, reliable overfill protection

Get simple, low-cost point level control to alert to high, medium, or low levels. Use in bins containing non-hazardous, free-flowing dry materials such as grains, granules, or pellets. When material presses against a microswitch, it activates a relay that is wired to a horn or light as an alarm, or to start or stop a process.

About us

Garner Industries Lincoln Nebraska USA  BinMaster/Garner Industries is located in Lincoln, Nebraska, USA.

Operations that struggle with the challenges of inventory management and timely replenishment of all types of powders, bulk solids, or liquids can monitor silo levels on their smartphone, tablet, or desktop with complete solutions from BinMaster. A complete suite of continuous level sensors, point level indicators, material management, and inventory monitoring devices and software simplifies material management while keeping people safe from the risks of climbing silos.

The Lincoln Nebraska, USA company manufactures sensors and software used for monitoring levels in bins, tanks, silos, chutes, and hoppers. Continuous level measurement options include SmartBob cable-based, guided wave radar, laser and 80 GHz non-contact radar, which are all compatible with Binventory™ software. Battery-powered, wireless laser level sensors are compatible with BinView® or FeedView® web apps for remote monitoring.

The unique 3DLevelScanner measures and maps material for volume accuracy and is the only sensor to generate a 3D image of silo contents. BinMaster is the exclusive worldwide supplier of this unique technology and has commissioned these sensors in bins containing powders and solids for over a decade.

Point level indicators provide automated level alerts using rotaries, diaphragm switches, capacitance probes, tilt switches, and vibrating rod level sensors. Dust detection devices alert to baghouse leaks and unsafe particulate levels. Flow detection sensors prevent cross contamination and assist with FSMA compliance for human and animal feeds. Aeration devices keep powders and solids flowing so they don’t pack in hoppers, along bin walls, or in the cone of the vessel

Robust, custom systems can be developed for a single site or networked for every bin, tank, and silo across a multi‐national operation. Add Stockpile Reports for pile inventory using images from an iPhone or drone to a SaaS dashboard. Monitor livestock feed inventory from a phone, tablet, or PC with the FeedView® web application.

BinMaster is US manufacturer certified to ISO 9001 quality management systems – requirements. For more information about BinMaster, visit www.binmaster.com.
