Continuous Level Measurement of Extremely Lightweight Specialty Materials

Application Notes & Case Studies /

The Monitor Technologies SiloPatrol® Inventory Monitoring System is a smart weight & cable based sensor system. This state-of-the-art weight & cable system is a proven problem solver, but will it work effectively on material less than 5lbs/ft³? Yes! The local Monitor representative arranged a demonstration and a unit was temporarily mounted on a skid and then placed on top of a large box of the material. It worked perfectly. The design of the sensor weight (an inverted cone design) and the electronics/mechanical design of the sensor allowed the unit to detect the surface of this lightweight material without sinking into the material.

Foundry Vibrators Help Produce High Quality Cores

Application Notes & Case Studies /

The MP Vibrator’s design incorporates a tab with a bolt hole, which allows for mounting to a wide range of machinery. This mounting methodology allowed for the vibrator to be bolted directly to the molding core plate, without interfering with the operation of the molding core machine.

The MP series, like all NAVCO vibrators, are machined to precise tolerances with quality materials, assembled with attention to detail, and factory tested to certify conformance to NAVCO standards. This process culminates with a complete solution resulting in a vibrator that provides long lasting operating life even in demanding environments. This makes it an ideal solution for service in the harsh environments typically found in sand casting foundries.

Stainless Steel Pipe and Chute Vibrators Improve Material Flow

Application Notes & Case Studies /

The Stainless Steel BH 1.25 Vibrator was chosen for the 304 stainless steel body, which makes it ideal for pharmaceutical facilities where washdown for cleaning and sanitation is required. The smaller diameter and the thin gauge construction of the pipe that the vibrators would be installed on made the BH 1.25 the ideal vibrator size for its high power to weight ratio. The efficient energy transfer of the impact type vibration made quick work of eliminating material buildup in the problem areas.

Stainless Steel BH Vibrators Help Spice Up Dinner

Application Notes & Case Studies /

NAVCO’s proposed solution included recommendations for positioning and operating the vibrator. The BH Vibrator was to be installed near the discharge, and operated utilizing a timer to provide a single impact at a set interval. The timer would be tied into the discharge valve, which would ensure the impactor only operated while the valve was open. The vibrator, valve, and timer would work together in sequence to ensure reliable spice flow out of the vessel and into the mixer in the desired amounts.

Level Sensor for Bulk Food Ingredients

Application Notes & Case Studies /

As a result of using a device that fills the bins very gently and slowly, the level in the bin increases very gradually. This reduction in fill rate can prove problematic with tilt type switches as it may be possible to gradually engulf the switch rather than “tilt” it to activate the switch output. The surface area of the tilt switch had to be increased if it was to be activated by the material and tilted to an angle of 17 degrees that would activate it. Making a larger size tilt switch would not be economical.

Eliminate Re-Calibration of Capacitance Level Probes

Application Notes & Case Studies /

The typical RF capacitance style point level sensor requires some form of calibration or “tuning” to the specific installation and application. Varying conditions in the environment (changes in ambient temperatures) can affect the stability of the calibration of these devices. Changes in ambient temperatures can impact the characteristics of electronic components, thereby causing calibration drift. In addition, the quality, or grade, of electronic components affects a probe’s ability to maintain a stable calibration.

High Level Detection in Finished Feed Silos

Application Notes & Case Studies /

The side load on rigid extensions from shifting materials in bins can present a challenge, especially when the extension needs to be several feet in length. Side mounting the rotary paddle bin level indicator can eliminate the need for extensions, but some feed applications can actually be very corrosive and can eat away aluminum over a period of time. Therefore, top mounted units are necessary to keep the housing of the bin level indicator from coming into frequent contact with the material. However, when the high-level detection point is 12 feet from the mounting point on top of the silo, side loads from shifting material must be considered. Dan Geiseke, Maintenance Supervisor at Hubbard Feeds in Mankato, MN wanted to eliminate these problems.

Gaylord Box Fill Station with Infeed & Accumulation Conveyors for Various Cereals

Application Notes & Case Studies /

NBE designed a custom box filling station for various cereals at 20 totes per hour. The Gaylord Fill Station was located in an area with a very low ceiling height. NBE designed around existing equipment with a fixed infeed tube. Light curtains and safety caging were integrated to eliminate operators from entering the processing area. The project included a Risk Assessment and Category 3 safety circuit control package.

Polished Stainless Steel Screw Feeders for Metering Snack Products

Application Notes & Case Studies /

For this project, the Customer required specially designed, food-grade screw feeders located under hoppers to meter dry cereal. The hoppers served to store out-of-spec cereal generated during startup or upset conditions. The out-of-spec product was typically of irregular size or color. The screw feeders metered the product into a tubular drag conveyor that conveyed the product downstream for further processing. Since the cereal was meant for human consumption, KWS took care to specify, design, and manufacture the screw feeders to meet the sanitary requirements of the Customer.
