Mechanical rotary power given from a motor must be driven by an appropriate amount of electrical power provided by the drive. Rotary power is provided for by the electrical input power and the rotary power cannot exceed the electrical. Therefore, it is important to verify the power throughout the system from power supply all the way to the motor or gearbox output shaft.

The Joint Inspection Group has recently release Bulletin 110 concerning the use of electronic water sensors in the aviation industry as an alternative to chemical water detectors.

Skydrol is a fire-resistant aviation hydraulic fluid that curbs corrosion and prevents erosion to various components. Converting components to be suitable for use with Skydrol is a process that needs to occur in order to protect the integrity and safety of the entire system.

Heat Trace and Electric Process Heaters are used in many critical processes in all plants.  It is extremely important that you and your team know how to properly test, install and maintain your electric heaters. Lack of attention in regard to these fundamentals will lead to costly heater shutdown and will cause an interruption in your process.

The use of INPUT/OUTPUT software filters can provide enhanced performance of controllers to process systems conditions. The use of Input filters are to reduce the erratic fluctuations of the analog input signal due to either electrical noise conditions or rapid fluctuations of the analog input signal. It accomplishes this by slowing down the response of the analog input to a change.

Graham Johnson, EMEA Product Manager for Parker Veriflo Ultra High Purity Fluoropolymer Valves, looks at the benefits of two point seal valves for semiconductor applications. The corrosive nature of high concentration acids and bases, clear chemistries and slurries used in semiconductor applications mean that pneumatic valves specified for these applications need to be particularly robust.

Rotork IQ technology is well established in the field of intelligent valve actuation. In addition to Rotork's double-sealed enclosure, non-intrusive commissioning, data-logging and predictive maintenance capabilities, the latest IQ3 generation features an extended range of advanced functionality and communication capabilities.

Rugged actuators that can handle a full range of ambient conditions are required in some of the more complex environments that produce oil. To provide comprehensive solutions to this precise actuation challenge, Valin has partnered with Valvcon.

In Jon Monsen's book, Control Valve Application Technology (published and distributed by Valin Corporation), Jon explains how to properly size and select a control valve. Jon recently received inquiries from customers interested in a further explanation of one of the graphs featured in his book. This article will cover that explanation.

In Watlow catalogs, brochures and web pages there is a category of controllers listed as Limits and Alarms. It is not always clear to everyone when to use these controllers or which type of controller to use. This document is an attempt to clear up some of these issues.

Occasionally questions come up with regard to calibration of Watlow controllers. This paper will attempt to address some of the more common questions on this subject. Many people want to jump in right away and begin performing a calibration procedure before verification. Before you would attempt to calibrate a Watlow controller, verify that the controller is in need of calibration. If you verify that readings of the controller first, you may not have to go through the more involved process of ch...

In this paper I will show how an analysis using Nelprof™ control valve sizing and selection software's unique ability to graph the installed gain of a control valve can be helpful in selecting the optimum pump for a balance of good controllability and minimum energy use.

Molybdenum disulfide is a naturally occurring black-colored solid compound that feels slippery to the touch. It readily transfers and adheres to other solid surfaces with which it comes into contact.

Probably the most significant trend in the instrumentation products world today is the design of increasingly corrosion-resistant systems. Led by oil and gas companies, instrumentation and piping engineers are now focusing far more attention on the materials used to fabricate valves, manifolds and tubing systems. In the offshore project world, for example, Parker Hannifin is currently seeing exponential growth in the use of 6Mo in preference to traditional 316 stainless steel. So, why are so man...

This article discusses the evolution of ferrule design and hardening technology, using the example of the Parker Hannifin CPI™ single ferrule compression fitting, but the basic principles also apply to two ferrule compression fittings, such as Parker Hannifin's A-LOK®, as well as the high pressure design.

Here are some essential steps to help ensure your instrumentation tube and fittings system is as safe as possible.

Customers who wish to control three phase heaters require power controllers. How do you decide which method of control to select? Two-leg versus three-leg control and zero cross versus phase-angle control need to be considered. The following will help you decide when each method is appropriate.

In today's world, there is an ever increasing awareness and focus on safety. A system designer needs to understand all aspects of design that can affect the safety and reliability of the system they are implementing.

Clean drinking water is the most precious resource on the planet.  Access to sanitary water is an essential element to a healthy, productive population.  While many consumers take it for granted that they have access to clean water coming from the faucets in their home and in public places, the companies responsible for making sure this is a reality understand everything that is involved.

Grocery stores require produce to be disinfected before being shipped to their outlet on a regular basis in order to ensure cleanliness before it is sold to their customers.  If left untreated, fresh fruit can be subject to a number of different contaminates that can ultimately adversely affect the consumers health. As the public is more conscious than ever about the substances and chemicals that they ingest, ensuring that produce does not harbor microbes is critical.

Digital pathology is a rapidly growing segment of invitro-diagnostics with the potential to streamline the overall pathology process for the benefit of both doctors and patients. This relatively new market segment requires motion systems that support both high quality and high speed imaging. In addition, the scanners are dispersed globally, which drives the demand for extremely high reliability. Lastly, as with all diagnostic instruments, laboratory space is at a premium, so minimizing the overa...

Almost everyone knows someone whose life has been touched by heart disease or cancer — the two leading causes of death in the United States. Today, researchers are using DNA sequencing to better understand the genetic links we have with diseases and how it can influence the course of treatment. We are standing on the edge of the personalized medicine healthcare revolution, which will be fueled by the widespread adoption of DNA sequencing as a diagnostic tool.

Cellular therapies are on the verge of revolutionizing how patients are treated for some of the most chronic illnesses. Cell therapies offer regenerative abilities that are giving hope to both patients and their doctors. However, there is still much work to do in the laboratory. In the article, Cell Based Therapeutics: The Next Pillar of Medicine, authors Fischbach, Bluestone, and Lin assert that Cell Therapies will become the Third Pillar of the drug industry alongside molecular and biochemistr...

With the advent of industry buzzwords like "Collaborative Robotics" and "Industry 4.0", machine builders of today are feeling increased pressure to provide a new level of intelligent and flexible automation. A revolution taking place in the industrial marketplace is the Industrial Internet of Things, which describes an industrial network of devices embedded with electronics, software, and sensors, capable of collecting and exchanging data to more effectively and efficiently drive machine behavio...
