Whether you are an engineer or a consumer, many daily applications involve capacitance. Capacitance can be measured using a capacitor, however it is not as simple as that. There are three different methods in which the capacitor measures capacitance. 

We have gone over the best practices for selecting a unidirectional and a bidirectional differential pressure transducer based on usage and application. So why should you use a unidirectional differential pressure transducer over a bidirectional model for an isolation room? When requiring an increased accuracy reading for positive and negative pressure, it is best to use a unidirectional transducer. For positive pressurized rooms, you can place the low port on the reference area and the high port on the room of concern. For negative pressurized rooms, you place the low port on the negative pressure room of concern and the high port on the pressure reference area.

Companies often resist change, especially when lacking direction, a defined end goal, guidance and leadership. It should be a top priority for executives to cut costs and streamline operations.  However, there may be several emerging barriers for companies to overcome in order to begin investing in energy management.

Material Compatibility refers to a material's resistance to corrosion, rust or stains when it comes in contact with a chemical.

The accurate measurement of humidity is important in many HVAC/R applications. Relative Humidity (RH) is a measure of the ‘actual humidity’, relative to the maximum possible humidity at a given temperature. RH sensors contain an assembly that is made up of an integrated sensor and transmitter. The sensor measures the RH while the transmitter creates an output signal proportional to the sensed RH. There are two common types of humidity sensing elements that are most widely used; Capacitive and Resistive.

Have you seen a large metal instrument, similar to the picture on the right, floating in the ocean and wondered what that device could be? What you have seen is a buoy (pronounced: boo-ee). A data buoy contains sensors used to monitor and collect atmospheric and oceanographic conditions.

When selecting a filter it is important to select the proper filter type, not only for removing undesirable material from a liquid stream but to ensure the filter meets the needs and requirements of the system.  Proper filter selection can be varied amongst industrial applications including water filtration, boilers, and irrigation. Filter selection not only encompasses the media and size of the particle that is being captured, but operational costs also come into play. Below three basic filter types to consider for liquid processing:

Hydrogen is used as a process media across many different industries and applications. Used in OEM equipment, pressure sensors play an important role in the safe, efficient, and reliable operation in material handling equipment, power generation, hydrogen production/distribution and many other applications.

Even with a pressure transducer, it can be very confusing to measure pressure. For one thing it may be diffcult to understand all the different pressure measurement types, and apply its application correctly.

Hopefully this presentation can clear things up:

There is no guarantee of a perfect, contaminant free cleanroom. However by adhering to room pressure requirements, proper gowning procedures and by understanding the origins of the contaminants, users can minimize contamination risk to ensure safe testing and manufacturing environment. These are some of the things you may not have realized can compromise a cleanroom, and some possible ways to reduce the contamination of the source.
