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.

Motors are used for numerous industrial processes, be it moving air with a fan, pumping water with a pump, or driving a mechanical process. It is important to know when motors are not operating properly or require maintenance.
Many installations rely on a sensor or instrument used for the primary process, such as the use of a pressure transmitter to verify system pressure in a duct or the use of a flow transmitter to verify flow in a pipe. When errors or loss of pressure/flow are indicated, maintenance personnel may be dispatched to remedy the issue. However, this method does not indicate the root cause of an issue. Relying solely on primary process instrumentation opens the door to an unforeseen, possibly catastrophic situation. Continue reading “Benefits of Using Current Switches/Transformers”
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.
