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.
Humidity sensors are one of the most common types of sensors used for HVAC equipment and building management systems. With proper humidity monitoring, energy efficiency of a building can be improved. By using environmental conditions in conjunction with an economizer to reduce the building load, cool outside air is used to cool the indoor space of a building. Dampers, humidity sensors, and temperature sensors are used to verify optimal outdoor conditions for maximizing energy cost savings. Continue reading “Capacitance Polymer Humidity Sensors”
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. Continue reading “What is electrostatic discharge and how can it be prevented?”
As cities around the world continue to grow, the need to fit more parking and loading dock capacity into smaller spaces is essential for new municipal and commercial building plans. For personal vehicles, many designers turn to enclosed parking garages to fit as many vehicles in as small a space as possible, or to mixed-use structures that combine a parking garage with work or living space in one building. For commercial traffic, loading dock operators are designing docks and material handling systems to service shipping vehicles as quickly as possible.

Many people think that we get cold and flu viruses more often in the winter due to the cold temperatures outside; however, this can actually be attributed to the fact that we are inside more, thus being exposed to higher concentrations of pollutants. Poor indoor air quality can cause what has come to be known as sick building syndrome.
