pbs0611p6a.jpgAnimal Repeller
YardGard pest animal repeller deters raccoons from rummaging through garbage, dogs and cats from abusing yards, and deer from ravaging grounds and gardens. The electronic control device protects up to 4000 sq ft from pest animal damage in buildings, rooftops, warehouses, or other commercial, municipal, or industrial sites. This ready-to-use, portable one-pound unit is easy to install anywhere with keyhole slot mounts. The discreet deep-green colored unit blends with any outdoor décor and measures just 6.75 × 5.25 × 3.5 in. for an inconspicuous fit. Choose continuous operation or motion-sensor operation to activate only when pests move into the coverage zone. Powerful sonic and ultrasonic sound frequency (15–25 kHz) is adjustable depending on the pest. The weatherproof unit features a snap-on raincover to protect the controls. The dual-operation unit plugs into AC or uses four C batteries.

pbs0611p6b.jpgWeigh Feeders
The Model 407 Series of Weight-Loss Weigh Feeders features a compact design with a small footprint, resulting in low overall space requirements. Yet, the series is versatile, offering a variety of different metering mechanisms capable of metering a broad range of even the most difficult-handling dry solids materials. They incorporate the same robust design as the company’s other weigh feeders, featuring a high-resolution, non-load cell–based weighing mechanism that never requires field calibration or adjustment. The feeders are designed for the industrial environment and unconditionally guaranteed for five full years.

pbs0611p6c.jpgPressure Transducers
Company manufactures Schaevitz-brand pressure transducers for the harshest environmental conditions. The units provide maximum resolution at the required measured pressure range. These transmitters are built using rugged bonded foil strain gauge (BFSG) technology. The key to this capability is a pressure overload protection for the diaphragm, called the over travel stop (OTS). OTS enables the sensing element to handle a minimum of five-times full scale over-range pressure spikes without damage or drift. The pressure transmitters allow users to order based on the target range without fear of damage due to spikes. For example, instead of ordering a 5000 psi device to measure pressure in the 500 to 1,000 psi range with spikes of 5,000–10,000 psi, a user can specify a Schaevitz BFSG transducer rated to 1000 psi.

pbs0611p15a.jpgSResin Crystallizer
The APK-series resin crystallizer converts other amorphous plastics into semicrystalline ones so that a subsequent drying sequence is possible. In the process, the material is kept heated with constant motion by using an agitator during the crystallization phase, which prevents the clumping of the material during crystallization. Maximum throughputs for the APK 50–600 range are from 160 to 1764 lb/hr, with an operating voltage of 460/3/60. The APK 1000 and APK 2000 can be configured to meet specific processing needs. All APK-series crystallizers are designed for 24-hour operation and meet all CE requirements.

pbs0611p16a.jpgBulk Bag Unloader
Modular Forceflo options, in conjunction with the receiving hopper’s integral agitator and feed auger, help consistently feed material from a bulk bag into process equipment. The integral load cells and control package provide loss-in-weight batching capabilities for the material directly from the bulk bag. When an empty bag is replaced with a new filled bag, the controls retain the weight information and automatically dispense the proper amount of material to complete the batch weighment. The controls of the Forceflo bag-massaging options are interconnected with the material-flow-promotion devices in the receiving hopper to prevent the material from bridging or ratholing when the customer’s process equipment automatically calls for material.
