How to Measure Capacitance?

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.

Why should you use a unidirectional differential pressure transducer for isolation rooms?

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.

What is a data buoy?

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.

3 Types of Filters for Liquid Processing

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:

Types of pressure measurements

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:

What is the difference between True and Calculated Wet-to-Wet Differential Pressure?

After understanding the difference between wet-to-wet, wet-to-dry and dry-to-dry differential pressure transducers, it is time to learn about the different types of sensors designed to measure wet-to-wet differential pressure. Wet-to-wet differential pressure sensors are broken into two main categories, true wet-to-wet differential pressure and calculated wet-to-wet differential pressure.

What is the difference between Wet-to-Wet, Dry-to-Dry, and Wet-to-Dry differential pressure transducers?

Differential pressure is the difference in pressure between two points of measurement. This is commonly measured in units of pounds per square inch differential (PSID) or in inches of water column (“WC). Devices for differential pressures usually fall into one of these three categories:
