Setra is best known for pioneering the variable capacitance principle, the technological innovation behind capacitance-based pressure transducers. Variable capacitance transducers demonstrate industry-leading accuracy especially in low pressure HVAC and critical care applications with accuracies as high as ±0.25” water column (±0.009 PSI).
In many pressure sensing applications, high accuracy is a must-have. Whether you’re working with thousands of PSI or only a quarter inch of water column, the most demanding jobs require the best tools available. While there are many types of pressure sensing devices on the market, none quite match variable capacitance transducers in terms of accuracy and quality.

Although hydrogen is in its infancy as a fuel source, its future is incredibly bright. The technology behind hydrogen fuel cells is improving daily and its viability as a replacement to the internal combustion engine seems likely. Hydrogen is already being used in specialty vehicles such as forklifts and buses, and it’s only a matter of time before infrastructure is in place to serve the consumer automotive market. Why do hydrogen fuel cells have such great appeal? Because their only byproducts are heat and water vapor, making hydrogen fuel cells a truly zero-emission locomotive technology.

Capacitance is the ability of an object to hold an electrical charge. Capacitors are components in an electrical circuit that can store a charge and are considered one of the three fundamental electronic components along with inductors and resistors.

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.
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.

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.
