Insulation Tape Is Easy to Install
Series 945 Aerolon Tape is a self-adhesive insulating tape that controls condensation and improves thermal efficiency in industrial, water, wastewater, and architectural applications. It contains a blend of insulative particles with exceptionally low thermal conductivity. The tape is suitable for controlling condensation on processing equipment and piping with surface temperatures below 150°F (66°C). Available as 30-ft-long by 1.5-mm-thick strips in multiple widths, the tape can be layered to achieve the desired thickness, or applied in combination with Series 971 Aerolon Acrylic, a thermal insulating coating. The tape can be applied quickly and in cold weather, so it is particularly useful for projects where temperatures are too cold for Aerolon Acrylic to be sprayed. When temperatures drop below 50°F, an electric heat gun can be used to ensure proper adhesion. In addition to improving thermal efficiencies, the insulation tape helps resist corrosion under insulation (CUI) that can damage metal piping. The tape is suitable for use in the food processing industry, where spray-applied coatings are restricted.
Microbioreactor Drains Rapidly for Cell Line Screening
The ambr 15 Generation 2 cell culture system replicates laboratory-scale bioreactor performance on a small scale (10–15 mL) and controls up to 48 single-use bioreactor cultures in parallel. New clone selection software provides simplified, multivariate data analysis for faster, more-consistent cell-line screening and ranking. The bioreactor has a flexible workstation layout and an expanded tip bin capacity. A rapid vessel drain is useful for automated cell passaging and media exchanges so that large volumes of culture can be bled and the spent media can quickly be removed from the microbioreactors. The culture station design provides stirrer speed control that is suitable for sensitive cell lines. A robust screening platform for cell and gene therapy development can process HEK293 for viral vector production, T-cells, induced pluripotent stem cells (iPSCs), and other immune-system-derived cell lines. The culture passage steps and rapid vessel drain functionality adapt to different media for screening cell lines in the microbioreactors. New media mixing steps automatically create media blends, eliminating the need to premix, saving time, and reducing the chance of error. Automated serial passages ensure the stability of cloned cell lines.

Durable Flowmeters Are Suitable for Low and High Flowrates
The ST80 Series thermal mass flowmeters feature adaptive sensor technology (AST) — which enables them to measure in constant-temperature (CT) thermal dispersion mode during startup and through lower flow ranges, and then seamlessly shift into constant-power (CP) thermal dispersion mode at mid-range and higher flowrates. This allows fast response and a wide measuring range at low power consumption, which maximizes sensor reliability and reduces energy expenses. The meters have a rugged design with no moving parts. They provide direct mass flow measurement through a single process penetration, which reduces installation and labor expenses. The meters include dual 4–20-mA, NAMUR NE43-compliant analog outputs and HART and Modbus 485 communications. They are offered without a display, with a display, or with a display and programming buttons. A backlit LCD provides readouts of the flowrate and temperature, totalized flow, alarm conditions, diagnostics feedback, and a user-defined label field. The insertion-style configuration has a flow range of 0.25–1,000 std. ft/sec (SFPS) and the inline-style configuration has a range of 0.0062–1,850 std. ft3/min (SCFM). The flowmeters fit pipe diameters ranging from 1 in. to 99 in. (25–2,500 mm), and they can handle media temperatures up to 850°F (454°C). They are suitable for measurement of compressed air, hydrocarbon gases, single process or specialty gases, biogas mixtures, and more. The ST80 Series meters are housed in enclosures that are National Electrical Manufacturers Association (NEMA) 4X- and Ingress Protection (IP) 67-rated.

Metal Detector Scans in Multiple Orientations
The Interceptor-divergent field (DF) metal detector inspects vertically and horizontally concurrently and looks for thin, nonspherical metal contaminants. Rather than scanning a certain number of frequencies, the conveyor-style metal detector inspects products using multiple field directions. It utilizes two channels and two frequencies to choose the direction of the inspection field. The multiorientation, multiscan metal detector is especially sensitive to very thin metal contaminant flakes and foils that are difficult to detect on low-profile foods, including chocolate, confections, nutrition bars, cookies, and biscuits. The detector can also be used to inspect small, thin packages of conductive products. Multiple coil sets instantaneously drive the electromagnetic fields in different directions. Rather than missing a metal contaminant because it is not aligned with a specific field, the instrument looks for signals over a broad spectrum from multiple angles. The Contact Reporter software produces a full log of events to increase supply chain transparency and product traceability. These electronic records can be viewed, filtered, and exported, and can be used to supplement or replace manual documentation. Halo automatic testing can be added to reduce the risk of human error when manually testing the performance of the detection system.
Flowmeter Controllers Feature a Backlit Display
The PCU Series controllers connect with any thermal mass flowmeter to provide a local display of flow. Serving as single- or multi-channel mass flow controllers with up to four channels, the instruments support multiple-unit networked operations. A large, high-contrast backlit display provides remote, easy-to-read views of process variables and programmed setpoints for each connected device on a single screen. The controllers can handle batching, setpoint, resettable dual totalizer, and valve override control. Gas factor scaling allows their use with any fluid. Units can be programmed to provide visual and audible alarms for high and low flowrates. The devices can be configured from a keypad or via an RS-232 connection to a computer or programable logic controller (PLC). Built-in diagnostics ensure troublefree operation by testing system operating status, memory condition, communication adapter status, display functionality, and keypad operation at every power-up. The controllers are available in multiple configurations, including panel-mount, tabletop, and DIN Rail. Panel-mounted units are NEMA 4X-rated for protection against environmental conditions such as rain, snow, and ice. All units operate from 15 to 24 VDC and have a temperature range of 32°F–104°F (0°C–40°C).
Wireless Gas Detector Includes Upgraded Software
The Vanguard WirelessHART Version 1.2 gas detector features FLEXmount installation, which augments Vanguard standard mounting with magnetic and universal options. The magnetic option enables installation on I-beams without drilling. The universal option uses adjustable clamps that enable installation on pipes with diameters of 3–12 in. without a hot work permit. This detector incorporates enhanced calibration, configuration, diagnostics, and communications. It includes WiHART communication accessories, which enable users to extend system range, get more out of their installed HART instruments by receiving WirelessHART data via 4–20-mA inputs, and further extend range with powered repeaters. A touchscreen interface streamlines onboarding of the gas monitor to a WirelessHART network. Upgraded diagnostic software detects and warns of system faults. The software also provides more visibility into sensor messages, offers more ways to code the status of the signals, and ensures fewer false alarms. The detection heads are interchangeable for hydrogen sulfide (H2S), methane (CH4), and carbon monoxide (CO) detection, and beta testing is underway for ammonia (NH3) detection heads.
