Rotary Paddle Bin Level Indicator














Rotary Paddle Bin Level Indicator Product Line Does It All

 

Elburn, IL -- Monitor Technologies LLC is pleased to announce that it's line of rotary paddle bin level indicators is the broadest and most state-of-the-art available and is virtually universal in application for monitoring the presence and absence of powders and bulk solids.  The "rotary paddle unit" first came on the market in the mid 1950's and since 1958 Monitor Technologies has been leading the way.  

Monitor's rotary paddle product offering consists of the Model KA/KAX Bin Monitor and the SafePoint(R) Fail-Safe Bin Monitor unit.  Both models use the industry-first Monitor designed motor shut-off feature to enhance life and minimize wear.  In addition, both the KA/KAX and SafePoint models use a twist-on/off cover so there is no need to mess with bolts, and this makes the initial install and any maintenance quicker and easier to perform.

The Model KA/KAX units meet ordinary and hazardous location requirements, can detect bulk solid materials from 5 pounds per cubic foot and up, and can be used in applications where the process temperature can be up to 750 degrees F.  These units are also very cost effective with a complete system starting at around $200 US.

The SafePoint(R) rotary paddle unit is a unique fail-safe rotary paddle unit that uses patented technology with Hall-effect sensors to continuously monitor the electrical and mechanical aspects of the sensor itself.  The self-validating techniques combined with patented technology, ordinary and hazardous area approvals, high process temperature handling capability, a twist-on/off cover and a purchase price around $300 make this unit the most viable device for critical point level measurement applications wherever bulks solids are concerned.

Monitor Technologies LLC is a leading supplier of level, flow, particle emission and aeration instrumentation for the worldwide powder and bulk solids market. The experience and market knowledge gained over five decades has earned Monitor a reputation for providing high quality and reliable product solutions.  Monitor is located in Elburn Illinois, give us a call today and let us put our creative solutions to work for you!

Solids Flow Monitor - SFI  
SiloPatrol® SE
Measuring coal powder levels when nothing else will work ….

Coal-fired power plants are commonplace around the world.  In order for these power generating stations to create huge amounts of electricity the turbines need to be feed with steam and the steam created by boilers that are fired by … yep, coal.  But coal as it comes from the mining operations is not what is fed to the burners.  First it is ground or pulverized into powder.  It is not unusual for the coal powder to be stored in silos awaiting the demand for it to be fed to the burners.  The inventory of coal powder in these silos needs to be monitored to allow for efficient operation of the power plant.

So, how do we monitor the inventory of coal powder in a silo?  Not easily.  In one typical application the power plant personnel found that the only technology that would work reliably is the modern smart weight & cable system from Monitor Technologies LLC, the SiloPatrol® SE.

Anhui Tongling power plant in Anhui province in China had tried almost ever technology possible to get a reliable level measurement in their 5 coal powder silos.  Radar, ultrasonic and others were tried, but none worked reliably.  It wasn’t until Beijing Conasen walked in and proposed that the Tongling plant use the SiloPatrol SE smart cable-based inventory monitoring system that the power plant personnel found a reliable solution.

Mr. William Yuan, sales manager for Beijing Conasen indicates that the power plant tried many major brands of ultrasonic, radar, and other technologies but that due to good relations with the Tongling plant personnel he was able to sell three SiloPatrol SE model SMU sensors and an HMI operator interface to them.  The units were installed by plant personnel.  Because of the heavy amount of coal dust in the silos an air purge using dry compressed air was used.  The SiloPatrol sensor incorporates the patent-pending use of Hall-effect sensor technology, a split-compartment enclosure, microcontroller, redundant optics and many other valuable features and technology to ensure reliable measurement even in challenging dust applications like coal powder.

The SiloPatrol SE system has been working reliably and the plant has since purchased two additional sensors and connected them into the same HMI operator interface.  This same sensor technology is working reliably at other coal-fired power stations in China as well.
