Simply put, barometric pressure is the measurement of air pressure in the atmosphere, specifically the measurement of the weight exerted by air molecules at a given point on Earth. Barometric pressure changes constantly and is always different depending on where the reading takes place.

Looking at your electric bill can be a daunting task. There are many factors that can affect your bill’s total — factors that are only amplified in large commercial and industrial sites.

One such consideration is peak demand. Peak demand is the largest instance of power usage in a given time frame, typically a rolling fifteen minute window. Measured in kilowatts (kW), peak demand is different than consumption. Total consumption  is measured in kilowatt hours (kWh) over a given period of time (e.g. monthly, quarterly, etc.). 

Stainless steel (SS) comes in all shapes, sizes, and compositions. It’s an alloy comprised of several different elements such as iron, nickel, and chromium with superior corrosion resistance compared to its constituent parts. Different applications require different material properties. In fact, there are dozens of individual grades of stainless steel alone, each with a unique proportion of ingredients and application benefits. This article will focus on two types in particular: 17-4 and 316L stainless steel.

The power flowing through an alternating current (AC) load isn’t always pulling its full weight. Every AC circuit has some degree of non-working power as part of its total power reading and this can affect the amount of power a system is truly drawing.

Many environments within a health care facility require pressure monitoring in order to protect patient health. Even spaces like hospital linen closets require some sort of indicator of positive or negative differential pressure.

It is commonly known that gowning procedures and air flow requirements are essential to maintaining a sterile clean room environment. Workers and operators don’t realize how crucial employee training is and the enormous impact employees have with the sanitation of the cleanroom. Unfortunately, humans are considered to be the biggest threat to the cleanroom and the largest source for contaminants, accounting for 75% to 80% of particles and microbes generated in a room. Understanding how personnel create particles and microbes or bring in contaminants, can help structure proper employee training, greatly bringing down the risk for clean environment contamination.

In the pressure sensing industry there are many different sensor technologies, but all sensors can be broken down into two classifications; oil-filled, non-oil filled. An oil-filled sensor refers to a sensor that uses oil as a transfer medium between a diaphragm and the sensing element. Oil-filled sensors appeal to many manufacturing applications due to its material compatibility, low cost, and ease of implementation. Although these sensors are becoming a standard, there are several drawbacks to selecting an oil-filled sensor over a non-oil filled sensor.

Whether you are looking for a solution to solve a tank level measurement issue to a building or trying to monitor a process tank within your factory, the proper tank level is extremely important to the success of your project. There are countless applications across many industries that with a few simple steps can ensure that you can meet the needs of your project.

What is Water Hammer?

Water hammer is shock wave produced by the sudden stoppage or reduction of a fluid flow. This can cause sudden rises in pressure and damage instrumentation. In tank level measurement applications, high pressures can be generated by the sudden closure of a valve on an outlet line. Although it might seem to be a consistent flow, the water inside pipes tumbles as it moves through.

Calibration is important regardless of what type of pressure you are monitoring.

Calibration is especially significant for low pressure requirements in critical applications such as vivariums, pharmaceutical manufacturing, cleanrooms and hospital isolation rooms. Other applications for low pressure include medical instrumentation, environmental pollution control, boiler combustion efficiency, air flow and research and development test stands.
