Industry Standard Point Level Indicator Is "Technician Friendly"


Elburn, IL –When installing, or performing maintenance on, your chosen rotary paddle bin level indicator have you ever had to juggle the cover and several bolts? Now, you don't have to. The "technician friendly" Model KA/KAX from Monitor Technologies incorporates an industry leading screw-on cover, easy access to power and output terminals along with two conduit entrances, and provides reliable operation for high or low level indication of whole or processed grains and feed materials. Using state-of-the-art rotating paddle technology, the KA/KAX employs the industry-first motor shutoff feature that extends the life of the motor beyond that of units that simply stall the motor when material impeded the paddle. That means your KA/KAX from Monitor will last longer.

The combination of being longer lasting and easier to work with means that the Model KA/KAX from Monitor Technologies is the best choice and highest value of rotary paddle bin level indicator on the market today. In addition, its high temperature version will allow for operation with process temperatures up to 750 degrees F. In addition, the Model KAX is suitable form Class 1 and 2 hazardous locations, while the KA is suitable for use in general purpose Ordinary Locations only.

Monitor Technologies LLC has pioneered level measurement for powders and bulk solids for five decades. The experience and market knowledge gained 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!



Spotlight: RF Capacitance Level Sensor
TrueCap Level SensorsTrueCap Light  
TrueCap® MK-2
Advanced RF Capacitance Level Probe

The TrueCap® Model MK-2 RF Capacitance point level probe is designed to provide a superior and stable sensitivity threshold making it suitable for a variety of powder / bulk solids and some liquid or slurry applications.

Advanced features of the Model MK-2 include:
> Automatic immunity to material build-up on the probe by its driven shield design
> Push-button calibration
> Enhanced temperature compensation
> Maximized reliability via smart sensing algorithms like “self-validating” fail-safe protection
> Visible status LED on ordinary location units
> Versatility through a variety of configuration options including: hazardous location version, split architecture design, quick-connect process connection, stub probe, cable extensions, solid extensions, Nylon® probes, Ryton® - equiv. probes, etc.

A practical application for the TrueCap would be to use this level sensor where a residual material build-up on a different sensor would cause a false material level indication.

Principle of Operation for the TrueCap RF Capacitance Level Probe:
The vessel wall and the active probe element establish an impedance reference between each other when exposed to air which has a dielectric constant of 1. When materials with a dielectric constant greater than 1 are in close proximity to the probe, the impedance of the sensing field between the sensor and the vessel wall will change. Once the amount of change exceeds a threshold that was electronically determined during the calibration process, an output relay will either be energized or de-energized depending upon the position of the fail-safe selector on the probe’s electronic circuit board. A change of as little as .5 pico-farad is all that is necessary for the probe to sense the presence of material.
