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 many choosing that particular material?

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 consumer’s 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 overall footprint is critical.

Selecting the correct chemical metering pump can be a daunting task because of the variations and types of chemical pumps available. In order to pick the best metering pump for the application you will need to consider several factors. For the sake of simplicity, we will limit our discussion to pumps that deliver no more than 50 gph and pressures of less than 250 psi.

There are very few elegant solutions for mid-to-large scale heavy industrial applications that require compact, high-temperature heating sources capable of delivering precise heat energy to a targeted location.
For US industries, the startling reality is that baby boomers are retiring at a rate of 10,000 people a day—it’s an exodus of not only skilled employees, but also “tribal knowledge,” learned on the job within industries or work plants and rarely captured in any manual or textbook.
It’s a startling fact that baby boomers are retiring at a rate of 10,000 per day. These men and women are leaving critical job functions, often at the heart of organizations. When senior management, executives, maintenance technicians, and engineers retire, they leave behind a gap that’s hard to fill.

In recent years, portable filtration units, often referred to as filter carts, have become a common tool in the lubrication professional’s arsenal. Increasing demand for these systems has led to the development of a wide range of new products and driven down prices, which is a good thing. When filter carts first came onto the scene they were primarily used by service providers for decontaminating large systems. These early models were typically designed for low viscosity oils in large volume systems and were on the expensive side, making them unsuitable or impractical for many applications.

The purpose of a filter is to remove contaminants from a fluid stream either completely, or at least down to a given rating or specification. Filters are used to help control contaminants and are rated according to their ability to remove these contaminants from a liquid, gas or air stream. There are different methods in which the performance of filters are specified.

Answer a number of key questions to identify the most appropriate choice
At process plants, a significant percentage of measurement devices aren’t correctly matched to their application, leading to decreased quality and consistency of the operation. Often, the source of this problem is the assumption that one type of level measurement sensor suits multiple applications.

There are two strategies for reducing control valve noise:
1. Source control, that is doing something to the valve to make it less noisy, and
2. Path control, that is doing something to prevent the noise from reaching the people who would be bothered by it.
