RF Capacitance point Level Sensor
Use Temperature Sensor and Microcontroller
Elburn, IL - The TrueCap® Model
MK-2 RF Capacitance Point Level Sensor from Monitor
Technologies has been redesigned. In addition to the
reliable attributes associated with the TrueCap line,
the Model MK-2 boasts exciting features that make it
optimal for point level applications. Value added
to your use of the unit includes the elimination of
recalibrating sensors and false indication of material
presence/absence.
Unlike other sensors, the new MK-2 uses a temperature sensor to detect changing
ambient temperatures to adjust its calibration automatically so that the unit
provides the highest degree of calibration stability. This, in combination
with a superior technical electronic design using industrial and mil-spec grade
components, means that you get true readings with long term reliability. In
addition, the unit features a universal power supply (48-240VAC or 24-48 VDC),
new housing with a twist on/off cover, local visual indication and dual conduit
entrances for easier wiring access.
In addition, the TrueCap Model MK-2 is available with both Class I and II Hazardous
location approvals allowing one model to serve virtually any application. For
ordinary locations, the MK-2 has the CE Mark.

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.
