New RF Capacitance Level Control Boasts Universal Power Supply & Automatic Build-up Immunity

Elburn, IL: Monitor Technologies LLC is please to announce it’s TrueCap® Model MK2 RF capacitance point level sensor with advanced state-of-the-art features that is rugged and reliable enough to meet the needs of the feed and grain processing industries. The Model MK2 provides a universal power supply of 48-240VAC / 24-48VDC accepting any supplies that meet these specifications. In addition, the Model MK2 provides automatic immunity to product material build-up that can occur on the probe, pushbutton calibration and sensitivity selection as well as a built-in ambient temperature sensor that combines with the MK2’s microcontroller to provide automatic calibration compensation for the most stable and reliable RF capacitance point level sensor available today.

Monitor Technologies LLC continues to pioneer level measurement and bin level indication for the worldwide feed and grain processing markets. The experience and market knowledge gained over five decades has earned Monitor a reputation for producing products that are "engineered to be the best" and providing customer experience “far better than” other suppliers.

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.
