This week is Air Quality Awareness Week, which is promoted by AirNow to discuss the importance of healthy air for everyone. One vital part of air quality involves monitoring humidity and temperature, so using an accurate outside humidity and temperature sensor can have a significant impact.
Most air handling units (AHUs) use what is called an economizer cycle. This is when outside air is mixed with the return air to cool the building dependent upon the outside temperature. However, if the air is too dry and requires humidification to accomplish this process, your cost savings may have been eliminated due to the AHUs humidity control, which provides excessive steam for this humidification procedure to take place. Consequentially, sometimes based on weather conditions, your economizer may just be costing you money instead of saving it. Continue reading “Outside Air Humidity”
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.

Calibration is the comparison and adjustment of a reading from an instrument in correlation with the reading of a higher accuracy piece of equipment. The overall goal of this process is to minimize measurement uncertainty and ensure the accuracy of an instrument.

In today’s industry, the number of device output signals continues to grow. Each signal is different; so how do you figure out which one is right for your application? The easiest way to hone-in on the correct signals for your application is to decide whether you want a digital communication signal or an analog signal. Continue reading “Analog vs. Digital Device Signals”
At one point or another we have all been exposed to some form of an electrostatic discharge (ESD) event, even something as simple as walking across a carpeted space, touching a door knob, and receiving an unexpected jolt. These types of events are very common in instrumentation applications. Today we will discuss what ESD is, the effects it has on instrumentation, and the steps that Dwyer Instruments has taken to prevent damage to sensors susceptible to these events.
