Silo Inventory Management Integrates With
Multiple Sensor Types

Elburn, IL -- The manufacture of polymer reinforced structural products uses multiple products including aggregates and resins.  Managing the raw material inventory of these items requires the use of differing level sensor technologies that are best suited for the target material and application.  In addition, this inventory of raw material must be managed properly as it can affect the cash-flow and income of the manufacturer. Monitor Technologies LLC uses its SiloTrack V3.53 inventory management software in just such an application to provide the benefits of improved inventory visibility and management of reordering and inventory control. Production depends on proper inventory management and accounting can insist on it.


SiloTrack V3.52 is a smart system using Server and Client software. It can interface with up to 128 sensors, including smart cable-based and guided wave radar devices.  This novel approach means you can be assured of having accurate and up-to-date database of information right at your fingertips.  In a day-and-age that security is paramount, SiloTrack provides security for your data and your internal IT system with user/password protection and encrypted data passing between the Server software and any Clients. SiloTrack V3.52 provides both English and Spanish language for ease of use and utilizes your LAN, WAN/Internet or dial-up connection to transmit database uploads between Server and Client.

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.
