“Flexible” High Level Detection in Finished Feed Silos at Hubbard Feeds in Mankato, MN

PROBLEM:
“ I am tired of replacing motors in my bin level indicators. I need a very long top mounted extension and the side loads on the rigid shaft extensions seem to decrease the life of my bin indicator motors.”

EXPLANATION:
The side load on rigid extensions from shifting materials in bins can present a challenge, especially when the extension needs to be several feet in length. Side mounting the rotary paddle bin level indicator can eliminate the need for extensions, but some feed applications can actually be very corrosive and can eat away aluminum over a period of time. Therefore, top mounted units are necessary to keep the housing of the bin level indicator from coming into frequent contact with the material. However, when the high-level detection point is 12 feet from the mounting point on top of the silo, side loads from shifting material must be considered. Dan Geiseke, Maintenance Supervisor at Hubbard Feeds in Mankato, MN wanted to eliminate these problems.

SOLUTION:
The Monitor Technologies Model KA/KAX with a “flexible” extension was required to solve this problem. This would allow the Model KA/KAX rotary bin level indicator to be mounted on top of the 100 foot high silo at Hubbard Feeds and not subject the rugged rotary unit to unnecessary side loads and reduce life. Hubbard came to Monitor Technologies and a solution was developed. Monitor supplied its flexible cable extension in a 12-foot version and this has been working successfully for over a year.

Hubbard also prefers the Monitor unit over other brands because of the screw-on/off cover which eliminates the bolts common on other brands and they like Monitor’s motor shut-off feature. They are getting a best-in-class solution to their problem.

Spotlight: True Fail-Safe Level Switch
SafePoint Level SwitchSafePoint Light  
SafePoint®
"True" Fail-Safe Level Switch

The SafePoint rotary paddle level switch with a self-validating design detects material presence plus continuously monitors its own ability to function. The analysis includes sensor health and system power failure, which makes the SafePoint truly “fail-safe”. The SafePoint incorporates patented use of Hall-Effect technology, dual outputs to indicate both material presence and unit health, and microcontroller technology to continuously protect bulk solids processing and storage from the consequences of unknown sensor failure by providing immediate indication of a sensor failure and confirmation of proper operation.

Other practical features of the SafePoint include rugged construction, motor shut-off when paddle becomes impeded to maximize motor life, twist On/Off cover for bolt free removal, and local status indicating light (except hazardous location models)

A practical application for the SafePoint would be to use this "true" fail-safe product if undetected sensor failure could result in a catastrophic process problem.
