December 2010: Binatrol® Diaphragm Level Switch
Optional Hycar® Protective Cover Enhances Durability of Diaphragm Level Switch

Binatrol Diaphragm Level SwitchOptional Hycar Cover


Elburn, IL - The optional Hycar® (rubber nitrile) cover is designed to provide Monitor Technologies' Binatrol® Model G series diaphragm level switch with additional durability for use with more abrasive dry materials. The Binatrol diaphragm level switch is a reliable, low maintenance and cost-effective way to monitor high, low and intermediate levels of powder and bulk solids in storage bins, hoppers, silos, and vessels. The diaphragm level switch can also be used to detect plugged or backed-up conveyor chutes for some applications.
 
The Binatrol® is a surface mounted, minimally intrusive switch that makes it ideal for vessels limited in size or internal clearance. The Binatrol is installed to allow its sensing diaphragm to be exposed to the material being detected.  Bulk material contacting the unit transfers force to an internal lever arm assembly, which than causes the dry contact SPDT 15 Amp switch to be activated. Common material applications for the Binatrol include grain, seed, wood chips, sawdust, cement, powders, resins, pellets and more. Monitor offers a variety of diaphragm bin level indicators that can be configured with various switch sensitivities, diaphragm materials and approval ratings.  Also, the Binatrol diaphragm switch requires no input power.

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.
