Velocity Measurement and Environmental Effects

Differential pressure measurement can be beneficial in a wide variety of building automation system (BAS) applications.

One of these applications involves determining if a filter in your system needs to be cleaned or replaced. Filter health can be established by monitoring the pressure on the primary and secondary sides of a filter. A clean filter will typically have a baseline differential pressure generated as air flows through it. As the filter becomes dirty, this differential pressure increases.

When using a mechanical flow sensor, such as a pitot tube, differential pressure can also be used to determine flow velocity and volumetric flow. Continue reading “Velocity Measurement and Environmental Effects”

Ask the Expert: What is a data logging USB, and how do I use it?

What is a data logging USB?

A data logger is a tool used to record a variety of parameters, which can include, temperature, humidity, dew point, current, voltage, and carbon monoxide. The logger is used in the field to record data, then brought back to a computer to collect/graph what was collected. These data loggers are ideal for applications such as: calibration labs, environmental chambers, pharmaceutical plants, and storage warehouses.
