Factors That Influence Your Weight Indicator System's Accuracy

The accuracy of a weight indicator system depends on several factors. Even with high-quality weight indicator systems, certain aspects to consider substantially impact the system's precision.

Using your knowledge can assist you in analyzing the significance of these factors, such as the nature and location of the application and other possible factors that may affect its accuracy.

Following are factors that can affect your weight indicator system's accuracy:

1. Load Cell

In any electronic weighing equipment, the load cell is the primary element. A load cell, also known as a transducer, directly converts mechanical force into an electronic signal. When a weight exerts a force on the load cell, it responds to this change.

A compression mounted load cell, often located underneath the weighing system, contracts when applied with force. It subsequently generates an analog output signal proportionate to the applied weight, transmitted to a controller. A defective load cell can lead to inaccurate weight readings, affecting the accuracy of the weight indicator system.

2. Environmental Factors

The precision of the weight indicator system also depends on the surrounding environmental conditions. If there is a vibration source nearby the system, such as working machinery, delicate loads can misjudge the vibrations, leading to inaccurate weight readings.

Placing large objects and materials on the weight indicator system can damage the equipment and the load cells if the magnitude of the applied force exceeds the optimum rated capacity.

If the air pressure in the calibrating setting differs from that in the operational environment, it can hinder the accuracy of the weight indicator system.

Air movement via air ducts or cooling equipment can influence the readings of a weight indicator system, depending on its location. Dirt and other debris on the scale base can cause scales to accumulate weight if not maintained regularly

3. Interference

Since load cells produce an electronic signal that transmits to the scale's digital display, any interference during this operation can result in erroneous weight readings.

Over time, the build-up of dew, rain droplets, and other particles on the load detector can generate electrical impulses that cause signal distortion between the load cell and the display panel.

As the temperature rises, the wire impedance increase. This decreases the voltage, causing the scale regulator to present values that deviate from the load cell's result.

4. Sensitivity

A highly sensitive weight indicator system can detect the tiniest change in the output voltage of the load cell. Sensors with 0.1-microvolt sensitivity are the most advanced in the field. Sensitivity is a measure of how small is the calibrated division size.

Low-sensitivity weight indicator systems cannot detect the minute voltage changes, resulting in inaccurate measurements.

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

Most Common Oilfield Instrumentation Issues

Image
Oilfield instrumentation  is a system of measuring, recording, and analyzing parameters such as temperature, pressure, and flow rate. It’s used to monitor the production of petroleum and natural gas wells. Here are five common oilfield instrumentation issues that oilfield operators should know about. Equipment Failure Equipment can either fail mechanically or electrically. The most common failures are due to power surges or lightning strikes. Electrical failure is one of the most common causes of oilfield instrumentation issues. They are caused by improper grounding or insulation issues with wiring in the wellhead. Mechanical failures  are usually due to wear and tear on moving parts caused by high-temperature environments or corrosion from corrosive chemicals in the wellhead. Lack of Communication Between the Wellhead and the Surface Any oilfield or gas field instrumentation is at risk of malfunctioning if the communication between the wellhead and surface is faulty. One issue that ca
