Self-Validating High Level Indicator Saves $Thousands in Costs
Elburn,
IL – When your high level sensor fails, when do you find out? If you’re like most people you find out when you overfill your bin or silo. Then you have to deal with the aftermath, which means cleanup costs, lost product, contaminated product, damaged equipment, maintenance and your boss breathing down your neck to get the production back up and running. One user of high level sensors tells that he estimates the cost of overfilling a silo to be about $5,000.
Today a new class of high level sensor has emerged, sensors that are “self validating” and not just simply fail-safe on power failure. The SafePoint® is the leader in self-validating high level sensors and provides "True" fail-safe protection. We are pleased to announce the issuance of a patent by the United States Patent Office that covers the use of Hall-Effect sensors as an integral component to ensure reliability of the self-validating techniques contained within the SafePoint bin level indicator. The SafePoint is the only device to use this reliable and safe technique to allow the instrument to self-validate its function to ensure safe process operation. While other devices use optical sensors that can be fouled with dust and other contamination, the use of magnetic Hall-effect sensing technology ensures full-time reliable self-validation and operation. The cost to prevent spills due to unrecognized high level sensor failure? About $300 for ordinary locations. Why use anything else?
The SafePoint bin level indicator's self-validating and patented technology continuously monitors its internal functionality and indicates its safe state to the user of the device. If through damage, electrical/mechanical failure or component malfunction the sensor is unable to operate properly, an output is immediately initiated to indicate a failed condition. This sensor health status indication is in addition to the standard output function indicating the presence / absence of material in the vessel at the point desired to be monitored. Local indication of sensor health and material presence/absence is also provided in all ordinary location units.
SafePoint bin level indicators are the best choice for safely indicating the level of powder and other bulk solids in bins, silos and tanks. Unlike other brands and devices available, the SafePoint reliably protects the user against overfilling and surprise outages using patented Hall-effect sensors.

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.
