  • Electronic Flow Control Valve (EFCV) with Pressure Compensation Capability

    A new concept for an Electronic Flow Control Valve (EFCV) with pressure compensation capability is introduced. Based on its embedded sensors and micro controller, the EFCV can provide flow control without the need of load/displacement/speed information from the power elements, like hydraulic cylinders or hydraulic motors.

  • Essentials of Industrial Ethernet

    Ethernet just celebrated its 30th birthday. In 1983, IEEE published the 802.3 standard as a draft and, ever since, Ethernet has come to dominate the commercial and consumer world. Every home PC comes with an Ethernet port, and virtually all communications are done via Ethernet—except in the industrial world.

  • Weigh Your Instrumentation Options: Switch, Transmitter or Hybrid?

    For decades, process instrumentation specifiers have faced the decision whether to use a mechanical switch or a continuous transmitter for a given application. Either type of instrument can be used to effectively control industrial processes and protect equipment and personnel -- and each has associated pros and cons. Application specifics typically drive decision-making, dictating which approach is most effective from performance, cost and lifecycle support perspectives.

  • Five Ways to Extract Value from Your Data Historian

    The data historian has long been seen as a venerable workhorse for engineers and technicians in the process industries, but changing economic conditions are forcing managers and executives to realize not only its importance but that it is a critical component to any process industry operation.

  • 10 Steps to Lean Electrical Controls

    Globalization is forcing companies to constantly become more efficient. To drive efficiencies, many companies are implementing Lean Manufacturing to stay competitive in this ever shrinking world.

  • Security for Industrial Automation and Control Systems

    The security of industrial automation and control systems becomes increasingly critical as different networks are connected and systems are integrated in a collaborative manufacturing environment. For industrial automation and control systems the potential impact of an attack maybe more serious than for computer systems in general. Users of industrial automation and control systems need to pay correspondingly increased attention to these issues.
