These prestressed concrete, egg-shaped digesters are custom designed to complement the digester technology inside and operate virtually maintenance-free for decades. They can be used for nearly any application, including wastewater treatment, food processing, organic waste digestion, and ethanol production. They are essentially self-cleaning. The egg shape is designed to provide the most energy-efficient mixing configuration and has a lower cost than conventional digesters. DN Tanks (El Cajon, Calif.).
The EP79FL is a two-part, electrically conductive epoxy for bonding, sealing, and coating applications. It has low-volume resistivity of less than 0.005 ohm-cm and is suitable for a variety of uses in the electronics, aerospace, computer, semiconductor, and electro-optic industries. In addition to its electrical properties, the system is flexible upon curing, enabling it to be used in applications involving thermal cycling as well as thermal and mechanical shocks. It adheres well to metals, composites, glass, ceramics, vulcanized rubbers, and many plastics while offering a T-peel strength that exceeds 25 pounds per linear inch. The system is serviceable in temperatures ranging from 4K to +275°F, enabling it to be used in cryogenic environments. It also has a convenient 1:1 mix by weight, and cures at room temperature or more rapidly at elevated temperatures. It can be applied with minimal sagging or dripping, even on vertical surfaces. The system is available in syringes, glass jars, or in premixed and frozen syringes. Master Bond Inc. (Hackensack, N.J.).
The KSV severe service knife gate valve is designed to withstand high pressures and abrasive slurries. Numerous features make this valve ideal for isolation in high-pressure, high-density slurry lines. The rigid one-piece body, 100% diameter port, hard-faced gate, and rotatable seat rings make it well-suited for rigorous applications. The valves are pressure/temperature rated to ANSI B16.34 Class 150 and 300, and are available in sizes 3 to 60 in. (80 to 1500 mm). DeZURIK (Sartell, Minn.).
The AST46DS explosion proof pressure
transducer features zero-function capability, voltage or 4–20 mA output
signals, and 316L stainless steel sensor materials for pressures from 1 to
20,000 lb/in.2. The voltage output signal is ideal for oil and gas
well-site applications. The transducer can operate as low an 8 VDC
and has current consumption with voltage outputs as low as 2 mA. The housing
has a special, layered paint suitable for NEMA 4X environments and salt spray
conditions. Using 316L stainless steel, the transducer is compliant to NACE
MR0175/ISO 15156. It comes standard with a 316L stainless steel 0.5-in. NPT
male process connection. Additional material options include Alloy 718 and
C276. Outputs of 1 to 5 V or 4–20 mA are standard. American Sensor
Technologies Inc. (Mt. Olive Township, N.J.).
The MINI analog family now includes two
universal software-programmable temperature transducers. These transducers
convert and condition signals from most common resistance temperature
detectors, as well as thermocouple temperature sensors. The new transducers
offer a wide power circuit input range of 9.6 to 30 VDC, making for
easy implementation into battery powered or remote systems. The transducers are
compatible with sensors with customer-specific temperature curves and sensors
that meet international standards. The hot-swappable signal conditioning slices
simply clip to the powering T-bus connector without removing bus bars or
bridging. Optional quick-cabling solutions also are available to interface the
modules to controllers. Phoenix Contact (Middletown, Pa.).
The UH104 four-port
mini USB hub is used to connect multiple peripheral devices to a single USB
port. Powered by the host USB port, the system provides downstream devices with
100 mA of power and high-speed USB connectivity at 480 Mbps. Designed for easy
mounting in harsh environments and cramped spaces, the hub features a rugged
acrylonitrile butadiene styrene plastic housing, built-in mounting tabs, a wide
(–40°C to 80°C) operating temperature capability, and the company’s signature
high-retention USB connectors that require up to 3.4 lb of force to
disconnect. The system is made primarily for industrial automation,
instrumentation, security, kiosks, point-of-sale, and laboratory market
applications. The hub is designed, tested, and proven rugged enough for
industrial EN61000-6-1 harsh environments. Its construction was validated using
IEC60068-2-32 drop testing and also adheres to 15-kV ESD protection and
FCC/CISPR Class B standards. B&B Electronics Manufacturing Co. Inc.
The new UC-8100 series computer and software
platform offer a complete monitoring service for any and all of the remote
field devices. The computer is designed to act as a compact, highly flexible,
vendor-agnostic data logger that connects to inverters, string combiners, smart
meters, and other devices made by any manufacturer. The computer transmits
collected data over Ethernet, Wi-Fi, or cellular netoworks. The software
platform collects data from multiple data loggers at multiple locations, and
enables systems providers to manage each data logger and attached device
remotely. Both the computer and the software package are scheduled for release
in early 2014. Moxa Americas Inc. (Brea Calif.).
