Chip resistors

Stackpole’s CSNL Series utilizes metal foil technology, which allows the CSNL to offer 1 percent tolerances and 50 ppm TCR in resistance values down to 0.5 milliohms. The CSNL Series offers sizes of 12 watt 1206, 1 watt 2010, and 2 watt 2512. The CSNL has excellent performance over life, temperature cycling, moisture, and short time overload with typical resistance shifts less than 0.5 percent. Stackpole utilizes high speed manufacturing for the CSNL to keep manufacturing costs to a minimum.

Touch-panel computers

Power management company Eaton announced the launch of the technologically advanced XP500 family of industrial touch-panel personal computers (PCs). The powerful, multi-touch, low-maintenance touch screen allows the user to pinch, zoom, rotate, scroll and finger swipe, just like a smartphone or tablet. Openness, sturdiness and ease of use are all packed into a premium, slim design.

Eaton developed the XP500 family especially to meet the requirements of plant engineers and machine builders. All solid-state memory and a fanless design means there are no moving parts that could compromise reliability in industrial applications. They are designed for use in harsh industrial environments, including hazardous UL/cUL Class I Division 2 applications, and can be connected to standard control systems via two independent Ethernet interfaces, as well as by its RS-485 and RS-232 interfaces.

All XP500 panel PCs can be easily integrated thanks to their fully open PC design, high reliability, and flexible configurability provided by the Windows Embedded Standard 7 operating system. XP500 PCs are available with widescreen sizes of 10.1 inches, 15.6 inches and 21.5 inches.

Mass flowtube

Schneider Electric has introduced a new advanced generation mass flowtube to its Foxboro Coriolis Solutions, offering high accuracy, reliability, installation flexibility and performance. It works with the CFT51 Coriolis mass transmitter to form the Foxboro Mass Flow and Density Meter.

By providing direct measurements of both mass flow and density, the CFS25 joins the family of Foxboro Coriolis flowtubes to deliver high accuracy and eliminate the problems of multiple process measurements associated with volumetric flow devices.

Using digital signal processing (DSP), the CFT51 improves flowmeter performance, particularly during two-phase flow, partial empty tube conditions and batching from empty operations.

This Coriolis flowmeter is not sensitive to varying process conditions. In addition to accurately measuring liquid, it also can be used in applications with entrained air, non-Newtonian fluids, viscous and abrasive fluids, slurries and gases.

Solar inverter diode

Cree Inc. (Nasdaq: CREE) has demonstrated that its best-in-class SiC MOSFET and diode technologies enable previously unattainable levels of power density in string solar inverter products, yielding greater than 99.1 percent at peak levels at one-fifth the average size and weight of today’s silicon-based inverter units.

Cree’s systems engineering team designed a proof-of-concept 50kW string solar inverter that exhibits a remarkable 50 percent reduction in power loss and operates at three to five times the switching frequency that conventional silicon technology can currently achieve. The combination of these two factors drastically reduces both the size and weight of the inverter’s cooling system, as well as its filtering components, which translates into a unit-cost reduction approaching 15 percent.

Additional applications that have been proven to benefit from Cree SiC technology include: industrial power supplies, induction heating units, battery charging stations, wind turbine converters, and traction inverters, amongst others.

Measuring microscope

Olympus Corporation launched the new STm7 measuring microscope, an industrial microscope system designed for highly accurate measurement of machined parts, semiconductors, electronic components, and other processed industrial materials.

The STm7 is available as both a manual Z-axis model and a motorized Z-axis model, each with a variety of stage options. Designed for highly efficient inspection and enhanced productivity, the STm7’s large square stage (up to 300mm x 300mm) can accommodate a number of variously shaped samples at the same time. The STm7 makes it possible to measure large samples such as printed circuit boards or semiconductor wafers with no shift in orientation.

The STm7 features a highly durable, vibration-resistant frame with a granite surface plate. It uses the same UIS2 infinity-corrected observation system harnessed by the industry’s most powerful optical microscopes.

Multi-stage pump


KSB offers a flexible multi-stage pump, the Multitec high-pressure pump in ring-section design.

Its impressive versatility is due in part to the great number of available options for customization, including six material combinations ranging from cast iron to super duplex steel to fit numerous fluid inputs including hot, cold, clean, seawater, or brackish. The pump can be installed horizontally or vertically and offers simple adjustment of the suction and discharge nozzles.

Customers also use Multitec pumps in power stations, industry (ATEX) and boiler systems.
