Attenuators are two-port electronic devices, consisting of a series of resistors that reduce the strength of a radio or audio signal. Attenuators are considered passive circuits as they work without the need for a power supply. They are available as either fixed attenuators with a fixed attenuation level or as a continuously changing attenuator.
For the reciprocating engine of an aircraft to optimally transfer power generated by the internal combustion engine to the propeller assembly, an apparatus known as the crankshaft is used. As an essential element of the power transmission system, crankshafts and their connecting rod convert the linear movement of a firing piston into rotational motion that is used to drive the propeller assembly. In this blog, we will discuss the design and functionality of the crankshaft, allowing you to better understand its use and importance in the realm of aviation.
A pressure switch is a common mechanical or electronic device found in various fluid applications, capable of activating when the pressure of a process fluid surpasses a setpoint or threshold. In order to determine that such values have been reached, a pressure switch may rely on various elements such as bourdon tubes, pistons, membranes, or diaphragms that exhibit changes when pressure is exerted. These elements are then attached to the contacts of the switch, allowing for the device to open or close based on its configuration and design. Finding use in gas systems, HVAC equipment, instrumentation, piping, and other settings, it can be highly beneficial to have an understanding of their working principle and parts.
Often used in conjunction with a bolt and nut, locking washers are extremely useful for securing components together. With the use of a locking washer, a bolt can take on heavier loads with a more even distribution of weight and maintain superior vibration resistance. As there are several types of locking washers that can be used for a variety of applications, it is essential to have a solid understanding of different options before choosing one.
Hydraulic power units, also known as hydraulic power packs, are systems that may create rotary motion, linear motion, or force through the use of enclosed and pressurized fluids. Hydraulic power units are self-contained, such systems comprising a motor, pump, and fluid reservoir. With the use of their assembly and fluids, pressure may be generated for driving parts.
Temperature refers to the physical quantity of heat or cold in an area or object, serving as a manifestation of thermal energy. Depending upon the application, various units may be used to express temperature, common ones being Fahrenheit, Celsius, Kelvin, etc. When one wishes to determine the temperature of a given object or area, there are also numerous tools which one may rely on to receive accurate results. Thermometers are a common device that measures temperature on a gradient, and they may come in a number of types to accommodate varying needs. With the pyrometer in particular, users may quickly measure the temperature of distant objects. As a tool that is regularly used in many industries and operations, having an understanding of the pyrometer and its functionality can be very useful.
Fiber optic technology has radically changed how we transmit information, allowing for signals to be relayed in the form of light pulses within glass, plastic strands, or fibers. As compared to conventional copper wiring, the speed, bandwidth, and distance capabilities that fiber optic devices provide are immensely higher and have not even reached their full potential in some applications. While many may be familiar with fiber optic internet or other similar implementations of fiber optic technology, others may not be aware of its growing importance in the realm of sensing. With fiber optical sensors, the physical properties of light may be used for the detection of temperature changes, strain, and other quantifiable conditions.
Hot melt adhesive, sometimes known as hot glue, is a form of thermoplastic adhesive designed as solid cylindrical sticks and applied using a hot glue gun. The gun uses a continuous heating element to melt the plastic glue, which is then pushed through the gun with a mechanical trigger mechanism or with direct finger pressure. When first squeezed out of the nozzle, the glue is hot enough to damage skin. It is sticky when hot, but solidifies in a few seconds to one minute. Hot melt adhesive can also be applied by dipping or spraying.
Bolts are a type of fasteners used to hold two objects together. They are used in a broad range of applications, but there are many factors to consider while selecting the right bolt for a certain use. Among these factors are the bolt’s shape, size, thread type, length, material, coating, and class of fit. However, in addition to these factors, the bolt grade should also be considered. You may be wondering what a bolt grade refers to and why it is so important. In this blog, we will discuss bolt grades in detail.
With conveyor belts and their related systems, a large amount of materials and items may be transported through automatic means. From manufacturing facilities to airport baggage claim systems, conveyors can increase the efficiency of a workplace by lowering safety risks, minimizing human errors, and reducing labor costs. With the various types of conveyor systems available on the market, understanding their differences and applications can help you make a more well-informed decision for your operations.
