Quick-Connect Process Connection for RF Capacitance Silo Level Sensor

 


Quick-Connect Process Connection Probe
(Shown with Optional Clamp, Gasket and Ferrule)

 

Monitor Technologies’ TrueCap^® Model MK-2 RF Capacitance point level sensor is available with a “quick-connect” tri-clamp process connection that provides easy installation and removal of the unit for cleaning purposes. This connection has no exposed threads and offers an affordable solution for basic sanitation situations not requiring 3A rating. The “quick-connect” tri-clamp is available for the Ryton® and Nylon (food grade) versions of the standard and stub probes. Also, it can accommodate both a 1” and 1-1/2” ferrule size.

The TrueCap^® Model MK-2 RF Capacitance point level sensor is designed to provide a superior and stable sensitivity threshold making it suitable for a variety of powder and bulk solids, liquid and 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 and maximized reliability via smart sensing algorithms like “self-validating” fail-safe protection.

Silo Patrol® provides level measurement for solid / liquid interface applications

  The Silo Patrol^® plumb bob “smart” level sensor from Monitor Technologies can be equipped with an optional stainless steel interface style plumb bob in order to provide continuous level measurement for settled solids in a blanket of water. The interface style plumb bob will penetrate through the water, make contact with the surface of the solid material and then retract to provide a level measurement. Examples of material applications that have been successful include sand, salt, corn, rice, potatoes and similar items that are covered by a layer of water. Interface with other liquids besides water may also be possible. Please check with Monitor regarding specific applications.

The SiloPatrol uses time-proven weight and cable techniques and combines Hall Effect sensor technology, state-of-the-art sealed bi-directional optical sensing, a split-compartment enclosure design, isolated outputs, SMT (surface mount electronic technology) and other valuable features to produce a rugged, reliable and accurate measuring system designed for the harshest and most dynamic conditions. In addition, a variety of operator interface devices and software, like SiloTrack software, are available to calculate and display material level inventory data.

Alarm for Backed-Up Conveyor Chute of Powder or Pulverized Coal

Monitor's Binatrol® diaphragm-style level switch is a reliable and cost-effective way to detect levels of powder and bulk solids in storage bins, silos and other vessels. In addition to level indication, the Binatrol® diaphragm switch can be used to detect plugged or backed-up conveyor chutes for some applications. For example, we have several companies that install diaphragm switches with the optional Hycar® covers to be used as alarms for backed-up conveyors of powder or pulverized coal chutes that provide feedstock to boilers.

The Hycar® (rubber nitrile) optional cover is designed to provide the Binatrol® Model G/GX series diaphragm bin level switch with additional durability for use with more abrasive dry materials like powder or pulverized coal. See image below.

The Binatrol® is a surface mounted, minimally intrusive switch that makes it ideal for vessels or chutes limited in size or internal clearance. Also, the Binatrol diaphragm switch requires no input power.

TrueCap® RF Capacitance Stub Probe Level Sensor for Tight Spaces or to Limit Material Flow Force on Probe

TrueCap® Stub Probe Version

The wide product selection is a major reason why Monitor's TrueCap® RF capacitance probe is a popular and versatile point level sensor for a large range of powder and bulk solid, liquid and slurry applications. Optional versions include high temperature, hazardous location, stub probe, food grade probe, quick-connect process connection, high level sensing with pipe or cable extensions and more. 

For instance, the stub probe model (a shorter version of the standard probe) allows the TrueCap to be used in tighter spaces, used to limit mechanical forces placed on the probe from material flow or to keep the probe out of the main material stream. In addition, the TrueCap design provides automatic immunity to material build-up on the probe by its driven shield design. Options for the TrueCap® stub probe model include a 3/4 inch / 1-1/4 inch combination process connection for replacement or new installations and a probe with white nylon insulator for food grade applications.

The photos above show a stub probe model of the TrueCap® installed in the unloading pit of a grain handling elevator set-up. The TrueCap sends a signal based on the system design requirements that involves the unloading pit connected to a drag conveyor that feeds the bucket elevator to move the grain to a silo. In this situation, the TrueCap stub probe version was chosen because the shorter probe will help to limit the amount of mechanical force on the probe from the material (grain) flowing into the pit.

Mercury-Free tilt style bin level switch solution

TC-3 Tilt Switch

    

The model TC-3 tilt switch is a durable, easy-to-install and cost-effective way to provide high level detection of bulk solids.  Tilt switches are used to prevent overflow of solids from storage bins or to control material levels in open piles.  The tilt switch can also be used to prevent over loading or under loading of material on conveyor belts. One example would be when conveying grain to open piles a TC-3 tilt switch can signal when it is time to reposition the conveyor.

Illustration B

Typically, the unit is suspended above the material being detected.  Rising material makes contact with the switch enclosure actuator, causing it to tilt.  When the enclosure body is tilted by more than 17 degrees, a steel ball rolls off center causing an internal output switch to close, providing indication of high material level (see illustration B). The change in the internal switch status is user accessible for signaling alarms, lights, or interfacing with a PLC.

Other practical features of the TC-3 include no calibration, only a few moving parts for minimal maintenance, and the unit is completely Mercury-Free.
Optional extension actuators are also available.

The model TC-3 tilt switch is constructed from cast aluminum and is suited for moderately sized materials having a density of 15-60 lb/ft3 (240-960 kg/m3) or particle sizes less than 2 inches (50 mm).  Common application materials include, but not limited to grain, feed, pet food, sand and plastic pellets.
