Torque Transducers

HBM (Marlborough, MA) offers the T40B and T40FM torque transducers that include an integrated speed measurement system. They are designed to work in harsh environments such as those that contain humidity, condensation, dust, oil, and grease. The transducers take measurements based on the contactless sensing of an anisotropic magnetoresistive (AMR) sensor, so the transducer signal is more stable than that of an optical system. The transducer integrates both the magnetic technology and the speed measurement sensor.

Linear Actuators

Zero-Max (Plymouth, MN) offers Roh’lix® linear actuators made from stainless steel for use where cleanliness is a priority. Used to convert rotary motion to linear travel, the actuators carry loads at speeds up to 70 inches per second, depending on size. Stainless steel components make the actuators suitable for food, drug, packaging, and similar applications where cleanliness and frequent system wash-downs are required.

Real-Time Software Enables Multi-Core PCs for Industrial Automation

As early as 25 years ago, industrial system integrators saw the great potential that the Windows operating system brought to PCs. They saw the possibility of using the advanced graphic capabilities that Windows offered versus the relatively primitive human interfaces of DOS-based applications and those of other proprietary OSes. Windows enabled the development of controllers with advanced human-ma chine interfaces (HMIs) that provide a whole new level of functionality, and make machines easier to use and maintain.

Using Source Measure Units to Characterize High-Power Semiconductors (Part 1)

The proliferation of electronic control and electronic power conversion into a variety of industries (e.g., energy generation, industrial motor drives and control, transportation, and IT) has made efficient power semiconductor device design and test more critical than ever. To demonstrate technology improvements, new device capabilities must be compared with those of existing devices. The use of semiconductor materials other than silicon demands the use of new processes. To be sustainable, these new processes must be tuned to deliver consistent results and high production yield. As new device designs are developed, reliability measurements must be performed on many devices over long periods. Therefore, test engineers must identify test equipment that is not only accurate, but scalable and cost-effective.
