Bin Level Indicators Provide
Flexibility and Reliablity

Elburn, IL – Monitor Technologies rotary paddle bin level indicators, Models KA/KAX, are reliable and built to be rugged, while maintaining a very economical price tag. The KA/KAX bin level indicator is designed to be used with a wide variety of bulk materials to eliminate bin overflow and maintain predetermined levels of powder and bulk solids materials.

The rugged design of the KA/KAX rotary paddle units is compatible with granular, pelletized and powder materials and can be used for high level indication of materials over 10 lb/ft³ (160kg/m³) and for low and intermediate level indication for materials over 5 lb/ft³ (80 kg/m³).

To increase reliability and exend the life of the motor and minimize maintenance of the unit, the KA/KAX will automatically shut off the motor while in a stalled condition with material present. In addition, losing cover bolts is a thing of the past now that the KA/KAX units have a twist on/off cover. Finally, Monitor offers a variety of interchangeable paddle assemblies to fit your specific application need.

Monitor offers a two-year warranty on all units. Contact Monitor Technologies for more information on our KA/KAX bin level indicators, or any of our full line of level, flow, and particle emission or aeration products.

Monitor's SiloPatrol® Inventory System has alot to offer

Elburn, IL. — Monitor's SiloPatrol® Inventory Monitoring System is a field-proven approach to reliably monitoring the level of material in bins, silos and tanks up to 150 ft (45.7m)in height.

The SiloPatrol system has excellent featurs such as:

• Industry – exclusive compartment, seals optical sensors from internal SMU environment too completely eliminate problems caused by contamination.

• Dual optical sensors ensure proper end of the cable detection without using the mechanical crimps or stops that can become jammed in cable pathway.

• Industry leading resolution of .01ft.

• Virtually a maintenance-free rugged design.

Monitor's SiloPatrol system also features a PC-based inventory management system. The SiloTrack™ software package provides a flexible graphical interface upp to 128 "smart" output sensors.


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.
