High-Temperature, High-Pressure Particulate Sensor
The Model PS 10 particulate sensor with ceramic insulation and a ceramic protective layer over the probe is designed for harsh processes with high temperatures and high pressures. For applications such as coal gasification, fluid-bed reactors in the plastics industry, kilns, high-temperature carbon black, and various combustion processes, temperature ratings up to 1600°F and pressure ratings to 1000 psi are available. The sensor housing does not have active electronics, ensuring high reliability. The sensor is remotely mounted to electronic control units with industrial temperature ratings of 160°F. The sensor monitors particulate emissions from fabric filters and particulate flow in process pipes.

High-Temperature Butterfly Valve
Featuring an inflatable seat, this high-temperature valve can operate continuously at temperatures up to 650°F in applications up to 150 psi (10 bar). The high-temperature valve provides a leak-proof seal by utilizing air pressure to expand the seat against the disc. The valve is suited for applications in which a bubble-tight seal is required—for example, hot gases, liquids, slurries, and abrasive materials. Standard sizes range from 2 to 30 in. The valve comes in a variety of construction materials and can be customized for each application.

Redesigned Lab Mill
This redesigned lab mill features larger grinding jars that are designed for low-cost small production capabilities. Up to six jars can run simultaneously and are made from all-polyurethane or solvent-resistant material with leak-tight covers. Slurry capacities are also increased to 0.45 and 1.32 L in this design. These round-bottom grinding jars offer improved wet grinding and dispersion with capabilities of 1-µm size reduction or better. Advantages include low contamination, narrow particle distribution, and safe product containment.

Large Indented PET Rounds
Alpha has added a new line of three indented, large polyethylene terephthalate (PET) rounds to its stock packaging for the nutritional industry. The 2000-, 2500-, and 3000-ml indented rounds fill a need in the industry for a single source for all three popular sizes. All three bottles are built off the same 141-g preform and feature a 110-400 continuous-thread neck. The rounds are ideal for large quantities of protein powders and bulk nutritional supplements. The indented label panel protects the label from scuffing during shipping and at retail, and the generous 110-mm neck allows consumers to use large scoops to measure the contents.

Reinforced PVC Hose
Flexadux R-2 hose is constructed of lightweight PVC, reinforced with a spring-steel wire helix, and comes in a clear FDA-approved version and a UL 94V-0 flame-retardant blue. Featuring good flexibility and a tight bending radius, this all-purpose hose has a 0.02-in.-thick wall and is ideal for a wide range of ventilation and dust- and fume-removal applications. Available in standard 1.25–18-in. ID sizes in 25- and 50-ft lengths with plain ends, the hose offers good compressibility and chemical and moisture resistance, and operates from 20° to 160°F. Metric and custom sizes up to 24 in. ID and custom colors can also be provided.

Plastics Feeder
Designed specifically for extruder manufacturers and compounders, the ProFlex C feeder offers maximum versatility in a package that is easy to operate, reconfigure, clean, and service. The ac-drive motor assembly and material discharge positions can be exchanged, optimizing the feeder’s ability to accommodate different mounting and clustering requirements for up to eight feeders. Additionally, the feeder supports both single- and twin-screw configurations, allowing it to easily be adapted to handle new materials and new application requirements in the future. The unit features an asymmetric, flexible, polyurethane feed-hopper and a six-point external agitation system that can be adjusted without influencing screw speed.

Sanitary Open-Construction Weigh-Belt Feeder
The MWF-OS sanitary open-construction weigh-belt feeder is used for processing snack food, cereal, pasta, pet food, and in any other application where hygiene and ease of cleaning are important. The feeder can provide either a “closed loop” gravimetric control of the material feed rate or an “open loop” control for precise convey rate output and totalization of an uncontrolled or intermittent material supply. The unit was designed for handling a wide range of materials and densities, excellent accuracy and stability, sanitary processing due to its all-stainless-steel construction, positive belt tracking without the use of mechanical devices, easy access with a low-maintenance design and no-tool disassembly, durability and stability under harsh conditions, and fast belt removal due to a cantilevered frame.
