O que é um fio de termopar? Tipos e usos, uma visão geral

What Is Thermocouple Wire?     Thermocouple wire or cable is used within a thermocouple that senses temperature using the point of cold junction compensation. Thermocouple wire is used to control instrumentation and for building the sensing point in a thermocouple and is made out of two dissimilar metals.   Overmolded Thermocouple cable   Usable Lengths of Thermocouple Wire   There are many factors that impact the usable length of a thermocouple. The two main factors that affect the usable length of thermocouple wire are total loop resistance and electrical noise. Thermocouple wires are made of different conductor materials. Because of this, the total loop resistance varies from based on the type as well as the wire diameter and length. However, the main goal for a usable length of thermocouple wire is to keep the loop resistance under 100 ohms. With the other factor, the longer the wire, the higher the possibilities of it getting influenced by electrical/radiated noise. This long length of the wire will then affect the performance of the wire. As such the usable length of thermocouple wire is recommended not to run or exceed a minimum of 10 feet. And in case the wire is extended it is recommended to use a shield to reduce the noise interference to an acceptable level. For this purpose, a metal over brad or twisted shielded wire can be used. At the same time avoid running wires closer to sensitive areas like motors and power wires. All in all, the recommended goal for a usable wire length is to keep the wire reduced to less than 100 feet with 20 AWG or thicker wire in an area free of electromagnetic interference. Now with the recommended lengths defined, let’s get into the types of thermocouple wires available and how they differ....

One of the most significant elements of an electronic or electrical system is the cable assembly. But still, it is one of the last components that is addressed or given importance to. In fact, an over or under designed cable assembly will have a tremendous negative consequence in the performance of the electronic system.   What is A Cable Assembly?   Cable assembly is a group of wires or cables that are organized and integrated into a single unit. Cable assembly is primarily used to transmit power, signals, and information to the designated application and to provide cables protection. Cable assembly also makes an application easy to use, repair and maintain. A cable assembly is also known as wiring looms or cable harness. You will be able to find cable assemblies of various sizes, colors, lengths, and sizes depending on the application. Anyway to give you a more detailed view on this topic I have an interesting flow of subheadings below.   How It Works   As we might know electronic devices and applications deal with many cables that are often overwhelming to maintain. Think of an instance where the cables are tangled and the pain to untangle them. This can even cause disruptions in the flow of signals and power. So what a cable assembly does is bring the different cable components in an application or device to a single unit in a neat and well-organized manner. This will prevent the cables from getting all over the place and make it easier to use and maintain. In addition, rough usage of cables and other unpredictable weather conditions can easily damage cables and disrupt their functioning. So under a cable assembly, all the cables are neatly bundled in an extremely durable sheet of material of exterior covering. This will thereby...

In fact, the success of an application and its relationship with wires and the overall flow of current is all anchored to how well a wiring harness is designed.   What is a wire harness?   A set Wire harness is the assembly of wires or electrical cables to transmit signals or electric power. The wires are bound by a durable material such as nylon tie in the assembly process. It’s the wire harness that ensures the reliability of effective energy and information transmission in an application. So there’s plenty more we can tell you about wire harnesses, but in the article, we’re going to give you a basic overview, the steps to guide you on design and construction.   Where Wire Harness Assemblies Are Used   Wire harness assemblies are used in a multitude of different environments. The motor industry, aerospace, military applications, consumer products, and even for home projects. Many of these applications will contain multiple wire assembly harness installations and many are integral to enable the machine, vehicle or product to work effectively.       When Wire Harness Assemblies Should Be Installed   Wire harness assemblies are used in a multitude of projects that contain and rely on a variety of wires and cables that function to complete different tasks. The challenge for most cable installations is that the cables and wires themselves are difficult to organize and keep straight and neat. A wire harness assembly can keep things better organized and help the project and installation install more easily and for the whole unit to...

O que é um cabo moldado? Tipos, usos, materiais, um guia de design útil

Cables are definitely one of the most confusing and complicating things to understand. Especially when it comes to choosing a cable that better suits applications. In recent times molded cables have become an attraction among many users. In fact, it’s now becoming one of the comfortable cable options for users.   What Is Molded Cable?   Molded cables are created by injecting heated molten material into a mold cavity. The mold mechanically attaches the connectors to the cables making it a single part. This gives the cable the ability to withstand vibration, shock, and flexibility along with good exposure to a harsher environment. Molded cables have become extremely important among many users. But many users rarely notice they use a molded cable. This applies to everyday objects; you perhaps didn’t know your phone charger had a molded cable. So let’s give you a clear guide on these types of cable.   How a Cable is Molded?   The molding process takes a great deal of pressure in forcing material into a mold cavity. It all starts by installing molding materials into the heated barrel of the molding machine. When heated, the material melts and turns into a resin. Any desired colorants can be mixed at this point. The resin mixed with the colorant is then forced into the mold cavities. After cooling, it will then take the appearance of the mold including any trade names, logos and so on. Pretty useful right? Now let’s see the types of molded cables you can come across. Cable Inner Pre molding In Mold 2 cavities After Over molding Types Of  Molded  Cables   There are many types of molded cables that are offered by different brands in the cable industry. However, they all more or less narrow down to the following types of molded cables.   Standardized Molded Cables...

Low pressure Molding, What Is It, How It's Used and Where, the Process   Low pressure molding is a technique we all see and encounter in our everyday lives, even though you may not realize it, low pressure molding is integral in many of the appliances and equipment you may use daily. It silently goes about its business and you probably don’t give it a second thought. Here at QL-Custom we have many years of experience with low pressure molding, so we thought we’d share some of the main points about this process with you in this article. Here’s a quick take away answer for you, then we’ll dive deeper into the process and benefits of low pressure molding, not only for applications but for the environment too.   So What is Low Pressure Molding? Low Pressure Molding is a technique for protecting and encapsulating components prone to damage, moisture, or other external influences. Typical in applications such as wiring and printed circuit boards. Using materials known as hot-melts, polymers are used to seal around components using specialist machinery.   Dimer acid based Polyamide materials often referred to as ‘hot-melts’, are thermoplastics that, when heated to specific temperatures become pliable and malleable for use around precious connectors and connections.     Why it’s called Low Pressure Molding   Low pressure molding, (or LPM) in particular, is as the name suggests, the use of lower pressure processes and techniques used where components may suffer from the normal pressure or extreme heat otherwise used in more industry standard pressure molding applications. To reiterate, there are two main reasons an application may require the use of Low Pressure Molding.   Malleability One major factor is the need for the applied thermoplastics to be more viscose. Viscosity allows the injected material to be applied...
