Why it's important to accurately measure barometric pressure

While changes in barometric pressure aren’t immediately obvious to human perception (except when your ears pop while hiking up a mountain), its effects can manifest themselves in many other ways. This is especially true in sensitive industrial and laboratory settings.

What Are The Different Types of Pressure Tests for Engine Test Stands?

Did you know that companies spend hundreds of millions of dollars on research and development for off-highway vehicle engines? A portion of the R&D goes into developing specialized engine test stands to ensure that the engines are functioning properly.

Engine test stands are complex, engineered systems designed to measure, control and record parameters during the different engine manufacturing stages.

What is overpressure and how can it be prevented?

Can’t handle the pressure?

Can you believe that pressure transducers are not always able to handle high pressure? Overpressure, or proof pressure, is a major concern for engineers and OEM designers when assembling machinery and selecting a pressure transducer. Overpressure refers to the maximum pressure value a transducer can withstand without affecting performance; it can also refer to a situation where the pressure value exceeds the limits. Although it is not ideal, pressure transducers can withstand occasional pressures up to their overpressure rating, eventually returning to their natural state. However, pressures that reach burst pressure, the maximum pressure that may be applied to the positive pressure port without physically damaging the internal sensing component, can rupture the diaphragm and cause leakage. Pressures above overpressure but below burst pressure can result in permanent diaphragm deformation, causing an output shift affecting operational performance or accuracy readings.

Are Your Heating and Cooling System Test Stands Compliant?

Recently, the Department of Energy (DOE) released a new requirement that goes into effect on Jan. 1st, 2017 as part of the "Energy Conservation Program: Test Procedures for Central Conditioners & Heat Pumps.” All manufacturers of heating and cooling systems need to ensure that the AHR units they manufacture for residential and small commercial applications meet this new standard.

What are the consequences of undetected leaks in a pressurized system?

The consequences of an unplanned leak in an air compressor may be higher than you think.  Air leakage can occur in any part of an air system, at any given time. Many users are blindsided by this issue. Air leaks are a significant source of wasted energy, often wasting 20-30% of a compressor’s output. Did you know that unmaintained plants waste at least 20% of air production capacity? In addition to wasting energy, undetected leaks can contribute to financial and operational losses.

Why do Test Stands Need Higher Accuracy Pressure Sensors?

In the test and measurement industry, manufacturers need to test the products they build. Pressure sensors are needed in test stands to measure pressure across various mediums, including air, fuel, coolant, gas. Testing can be expensive and having a reliable sensor eliminates costly downtime.
