When one is working within an interior space where odors, moisture, contaminants, and other undesirable air quality conditions are present, it is important to have proper circulation for the health and comfort of those affected. This is often done with the use of an exhaust fan which vents out unwanted substances in the air so that an indoor space can remain hazard free. Exhaust blowers can be implemented in many ways, often being a part of a heating and cooling system. As long as the fan can be placed in a way that it can direct air outside to be dispersed and there are proper wires and cabling in place, such installations can be fairly easy to establish.

Blower motors play a critical role in forced-air systems, enabling the circulation of conditioned air throughout varying environments. As is the case with many complex apparatuses, blower motors are also susceptible to breakdowns or failure. Usually going unnoticed for a while, blower motor failure can put stress on the system’s compressor, shortening its service life as a result.

Sprockets are profiled wheels that are capable of meshing with a track, chain, or various other perforated materials, serving to transmit rotary motion between two shafts. Sprockets find use in numerous settings, often being a part of pulleys, bicycles, tracked vehicles, and various machine assemblies. While sprockets are often compared to gears, they differ from such components in the fact that they never mesh directly with another sprocket. As there are many types of sprockets that one may procure, each of which may differ in their interaction, drive performance, and design, it is important to understand common variations and differences.

A current sensor, or current transformer, is a device that is used to measure the current traveling through a wire by applying a magnetic field to detect current and produce a proportional output. These sensors are placed around a conductor and are typically used with AC and DC current. They are beneficial as they allow operators to measure current passively without interfering with the circuit. Additionally, current sensors are essential electrical instruments that can also provide information regarding how much energy is being used by a system to ensure energy-efficiency. In this blog, we will provide an overview of current sensors, their distinguishing characteristics, and how they work.

A part of the generation, transmission, and distribution process of electricity, substations are used to convert high to low voltage or low to high voltage when applicable. However, to limit current and prevent an overload of electricity to sensitive components, reactors are used as dampeners for a range of substations. Constructed in the shape of a coil or capacitor bank, reactors provide substations with additional support to mitigate a short circuit from an influx of current. To better understand the importance reactors play in helping to regulate power system safety, we will discuss their commonly applied types and how they function.

When building a computer or replacing parts, it is important to understand the difference between various components and what they do. One crucial concept that those working with computers should be aware of when purchasing parts is the distinction between primary and secondary memory. It is also useful to be aware of the various types of storage that fall under the two categories such as ROM, RAM, hard disk drives, solid state drives, and more. In this blog, we will discuss the differences between primary and secondary computer memory as well as the common memory options that are available for use.
