The Rise in Digital Force Measurement Solutions

/0 Comments/in /by

In the early days of force measurement instrumentation and use cases, analog was king and, in many cases, still dominates most use cases. The fact that product manufacturers continue to provide analog solutions is steeped in the accuracy and reliability of the format.  Digital is changing this outlook and the rise of solutions that support digital output are on the rise.

Analog and digital signals are utilized for the transmission of information, typically conveyed through electrical signals. In both these technologies, data undergoes a conversion process to transform it into electrical signals. The disparity between analog and digital technologies lies in how information is encoded within the electric pulses. Analog technology translates information into electric pulses with varying amplitudes, while digital technology converts information into a binary format consisting of zeros and ones, with each bit representing two distinct amplitudes.

The primary difference between analog and digital is how the signal is processed. Analog signals when compared to digital signals are continuous and more accurate. Digital measurement solutions have come a long way and are growing in use and popularity due to overall trends towards digital transformation and modernization of testing labs.  Read Instrumentation Analog Versus Digital Outputs for further definition.

As more test and measurement professionals and labs are using digital instrumentation, the quality and accuracy of data output has skyrocketed. Primarily, it is much easier to gather and store digital data. This is often seen through the growth in wireless sensor technologies. Interface Digital Instrumentation continues to expand with new products.

Digital signals are stronger than analog signals, providing a better signal that is free from interference by things like temperature, electromagnetism, and radio signals. The data sampling rate is also much faster. As a result, load cells and other force sensors output signals transmitted to digital instrumentation can read and record hundreds of measurements in seconds.

Another major reason for making the switch to digital output is convenience and capability. Digital instrumentation opens a world of possibilities in terms of wireless data transfer, removing the need for wires and giving engineers more flexibility in terms of where to conduct tests, or monitor applications. It also allows for larger force sensor systems to work together on larger applications in which you need multiple data points on different forces around the object you are measuring.

Load Cells Versus Piezoelectric Sensors

/0 Comments/in /by

Load cells and piezoelectric sensors are used in all types of measurement applications. While both types of sensors are used to measure similar physical quantities, they work on different principles and have distinctive characteristics.

By simple definition, load cells measure the amount of force or weight being applied to them. The amount of force a load cell is engineered to measure is numerated by the capacity of the model specification and design, such as 50lbf (pounds-force) or 5kN (kilonewton). When a force is applied to the load cell, the metal body deforms slightly, which changes the resistance of the strain gages. This change in resistance is then measured and used to calculate the amount of force being applied to the load cell.

Piezoelectric sensors work on the principle of piezoelectricity. They are made of materials that generate an electric charge in response to mechanical stress, such as pressure or vibration. Piezoelectricity is a property of certain materials that allows them to generate an electric charge in response to applied mechanical stress, such as pressure or vibration. The word “piezo” comes from the Greek word for “squeeze” or “press,” which refers to the fact that these materials generate an electric charge when they are squeezed or pressed. When a force is applied to a piezoelectric sensor, it generates a voltage proportional to the amount of force being applied. This voltage can then be measured and used to calculate the force or weight being measured. Piezoelectric sensors are most often used in vibration and pressure tests.

Load cells are more suitable for applications where high accuracy is required, as they are more sensitive than piezoelectric sensors in detecting smaller changes in force. Load cells are characteristically more robust and can withstand higher loads without being damaged. Piezoelectric sensors, on the other hand, can be more fragile and may require more careful handling to avoid damage.

Load Cell Advantages

  • Higher accuracy: Load cells are more accurate than piezoelectric sensors, especially when measuring low loads. Load cells can provide precise and reliable measurements with minimal error, making them ideal for applications that require high accuracy. Read: Specifying Accuracy Requirements When Selecting Load Cells
  • Lower sensitivity to temperature changes: Load cells are less sensitive to temperature changes than piezoelectric sensors. This means that load cells can maintain their accuracy even when the temperature changes, while piezoelectric sensors may need to be calibrated frequently to maintain accuracy. Read: Understanding Load Cell Temperature Compensation
  • Better linearity: Load cells have a more linear response than piezoelectric sensors, which means that their output is more predictable and easier to calibrate. This is particularly important in applications where accurate and repeatable measurements are critical.
  • Higher durability: Load cells are more robust and can withstand higher loads without being damaged. This makes them suitable for applications where high loads are present, such as in heavy machinery or construction.
  • Lower cost: Load cells are often less expensive than piezoelectric sensors, making them a more cost-effective choice, especially for OEM use cases.

Piezoelectric sensors are used in a wide range of applications that require the measurement of vibration or acceleration. For example, piezoelectric sensors can be used in machinery and equipment to monitor vibrations and detect potential problems, such as imbalances or misalignments. They are the sensors used in cars to measure pressure, such as in tire pressure monitoring systems or fuel injection systems. Piezoelectric sensors are found in ultrasound imaging to generate and detect sound waves and in musical instruments, such as electric guitars or electronic drum kits, to convert vibrations into electrical signals for amplification.

Collaborative Robots Using Interface Sensors

/0 Comments/in , /by

Industrial evolutions continue to find new and innovative ways to use technologies, from AI to advanced robotics. What is not changing over time is the unique ability for humans to solve challenges and create new solutions. Pairing human ingenuity with machines to increase efficiencies and productivity is what we see today with the fast growing use of collaborative robots.

A cobot, short for collaborative robot, is a type of robot designed to work alongside humans in a shared workspace. Unlike traditional industrial robots, which are typically separated from human workers, cobots are designed to be safe and easy to use working side-by-side people. This interactivity is often referenced as part of moving from Industry 4.0 to Industry 5.0.

Cobots are typically equipped with sensors technologies that allow them to detect the presence of humans and react accordingly. This can include slowing down, stopping, or changing direction to avoid collisions or other safety hazards. Cobots are often used in tasks that are repetitive, dangerous, or require a high level of precision, such as assembly, packaging, or inspection.

One of the main advantages of cobots is their flexibility and ease of use. They can be quickly reprogrammed or taught new tasks, making them a cost-effective solution for many distinct types of manufacturing and assembly operations. Additionally, because they can collaborate with human workers, they can help to improve efficiency and productivity while also reducing the risk of injury or accidents.

In our new case study, Advancements in Robotics and Cobots Using Interface Sensors, we explore how are force measurement sensors used for cobots.

Force measurement sensors are often used in collaborative robotics to provide feedback on the force being applied during a task. This information can be used to ensure that the cobot is performing the task correctly and to detect any issues or errors that may occur. There are several types of force measurement sensors that can be used in cobots.

  • Strain gage sensors: Interface uses proprietary strain gages in our load cells. Use of this type of sensor helps to measure the deformation of a material in response to applied forces. They are commonly used in cobots to measure forces applied to a gripper or end effector.
  • Miniature load cells and load cell load buttons: Interface load cells of all sizes are used for both testing during design as well as embedded into the actual cobot for continuous monitoring. These types of sensors measure the force applied to a structure, such as a robotic arm or a part being manipulated by a gripper. Load cells can be used to ensure that the cobot is applying the correct amount of force to the part being worked on. Our smallest load cells are often used in the production and design of cobots.
  • Torque transducers: Interface transducers are utilized to measure the movement of robots, in rotation and for pivotal activity. These are critical in tasks on production lines, as well in unique industry cobots, such as entertainment.
  • Tactile sensors: These sensors measure the pressure or force applied to a surface. They are commonly used in cobots for tasks that require a high level of sensitivity, such as grasping and manipulating fragile objects.

Advancements in Technology Leads to Multi-Axis Sensors and Cobots

As use of cobots grows, so do the demands for using more data to define precision measured responses and actions. Multi-axis sensors can provide several benefits for cobots, as they allow for more accurate and precise sensing of the robot’s position, orientation, and movement. Here are some ways that cobots can benefit from multi-axis sensors:

  • Improved accuracy: Multi-axis sensors can provide more accurate readings of a cobot’s position and orientation, allowing it to perform tasks with greater precision and accuracy. This can be particularly important for tasks that require precision accuracy, such as assembly or inspection.
  • Enhanced safety: Multi-axis sensors can help to improve the safety of cobots by detecting when the robot is approaching an object or a person and slowing down or stopping to prevent collisions. This can be particularly important when cobots are working near human workers.
  • Greater flexibility: Multi-axis sensors can allow cobots to perform a wider range of tasks, as they can adapt to changes in the environment or the task at hand. For example, a cobot with multi-axis sensors can adjust its position and orientation to grip an object from a variety of angles, or to perform a task in a confined space.
  • Faster response time: Multi-axis sensors can provide real-time feedback on the cobot’s movement, allowing it to adjust more quickly and with greater accuracy. This can help to improve the speed and efficiency of the cobot’s performance.

Cobots are being used in a wide range of industries, as they offer benefits such as improved efficiency, precision, and safety. Some of the industries that are currently using cobots include:

  • Automotive: Cobots are being used in the automotive industry for tasks such as assembly, material handling, and inspection.
  • Electronics: Cobots are being used in the electronics industry for tasks such as assembly, testing, and inspection.
  • Food and beverage: Cobots are being used in the food and beverage industry for tasks such as packaging, sorting, and palletizing.
  • Medical: Cobots are being used in the medical industry for tasks such as assembly, inspection, and material handling.
