The Working Principle Of A Compression Load Cell


Compression load cells are instrumental for the operation of coil tubing units in oil rigs. They’re used in several industries including oil and gas exploitation, as measuring instruments. They operate on a working principle that’s crucial for measuring force.

Types of load cells can be broadly categorized into four groups: tension, bending, alternating, and compression load cells.
Load cells work like transducers that calculate and output force in the form of electrical signals. A variety of load cells detect pressure readings via strain gauges, although there are other forms of force sensors too.
It's a load that's designed to weigh down at one point to register the compression. They're good measuring tools for the pushing force along one axis. They're placed underneath a weighty object that needs to be measured. Contrary to that, tension load cells calculate the force with which they’re being pulled.

How Do Strain Gauges Work

When force is applied on the compression load cells, the strain gauge deforms. This gives your system the measurement of the load. Compression load cells can measure changes in resistance, depending on the load applied. Electronic measuring scales maximize the accuracy of measurements and reliability of the system.

Why Do Compression Load Cells Need To Be Sturdy

Oil rigs are situated in areas that experience harsh weather. The occupation adds more adversities that make the living conditions and job one of the hardest in the world. Therefore, the oilfield instrumentation used in the process also needs to be sturdy enough to withstand high pressure. Compression load cells are a classic example of that.

The substance used to manufacture compression load cells must be anti-corrosive and resistant to scratches. The oil rig sites may receive a fair share of rain, hail storms and snow, and the instruments need to face that without succumbing under it.
Damages to the base plate can affect the accuracy of measurements, and that can disrupt the operations. This is why the base plate is a hardened cover that's impervious to damage.

How Are They Accurate

Weight measurements are the linchpin of success in many industries, oil and gas being one of them. Slightest inaccuracies can translate into significant financial loss and inefficiencies. This is why compression load cells have to be highly accurate. The sing-point system in load cells offers great utility in industrial weight measurements. They are highly versatile and can register off-centre loads for maximum accuracy.
Customizable calibration services can turn these weight-measuring devices into long-term solutions for oil companies. These devices are quick to measure and provide results, which improves operations, cuts time and costs by a large margin.
If you’re looking for industrial-grade compression load cells and other oilfield instruments such as mud pressure gauges, custom cables, or clipper weight indicators, you’ve found them.
Contact Instruments is the sole manufacturer of OEM hydraulic and electronic instruments for industrial use in Canada, at their production facility in Leduc, Alberta. They're dealing with oilfield instrumentation for oil and gas companies.

How to Avoid OSHA Violations at Your Drilling Rig

Image
  The health and safety of workers in the oil and gas mining industry are major concerns. Exposure to hazards, extreme work environments, and accidents while operating heavy machinery means that oil/gas industry employees are at a higher risk of injuries and fatalities. As a result, the Occupational Safety and Health Administration ( OSHA ) has outlined certain precautions that help prevent accidents and keep your employees and worksite safe. Significant focus has been put on inspecting oilfield worksites, so you want to be prepared for any unexpected visits at your facility at all times. Staying prepared means that not only do you get to avoid fines and citations , but you also keep your workers protected. Let’s take a look at the top three violations on OSHA’s list, as well as the steps you can take to prevent them. 1. Inadequate Fall Prevention According to the National Safety Council, falls are among the most common hazards in the workplace, leading to approximately 50,000 severe i

What Is Overmolding And Why Is It Important?

Image
Overmolding is done through a process of injection molding in which two or more different materials are used to combine wires and make them into a singular component. To better understanding overmolding , it’s important to have a thorough understanding of how it works.   1.       The cable assembly is placed inside a mold 2.       Molten plastic material is poured into the cavity of the mold 3.       Once cooled, the plastic material solidifies into the shape of the mold and covers the junction point between the wire and its connector The Many Benefits Of Overmolded Cable So, why do people go through the trouble of combining wires into single components? The biggest advantage of doing so is increasing the longevity and reliability of cables and their components. ·          Better Flexibility With overmolding, the flexibility at the cable exit is strengthened. You might subject the cable to more pulling and strain near its connector, and with the help overmolding, there

What You Need To Know About Mud Pumps

Image
 If you're like most people, you've probably had a tough time finding the right mud pump with all the options available in the market This article will highlight some important things you should know before buying mud pumps. What Are Mud Pumps? Mud pumps are a machine with a vacuum that is used to pull water from low-lying areas and into the sewage system. The units are usually powered by electricity, but they can also be operated on gas or steam. They work by using air pressure to exert force on water, which then forms a stream in the pump hose. Once this stream is formed, it pushes the water through an intermediate chamber and out of one or two outlets before circulating back into the input chamber for re-injection. At this point, most mud pumps will have another outlet from which they can utilize the output flow downstream for agricultural purposes such as irrigation or crop flows. What Are They Used for? Mud pumps are usually used in municipal wastewater plants
