When a flex sensor (also known as a bend sensor) is placed on an object, we can measure how much that object bends. Choosing the right flex sensor is critically important if you're working on a project that requires them. In this tutorial, we will see the types of flex sensors, factors to consider when selecting a flex, how to tailor the flex to your project requirements, how to compare accuracy vs sensibility in flex sensors and tips for their installation and calibration.
Types of Flex Sensors
Flex sensors come in a variety of types. These are usually single-axis, dual-axis, and multi-axis flex sensors. Single-axis sensor: Flex sensors which measure flex only in one direction. Dual-axis flex sensors are sensors that can measure bending in two directions. Multi-axis flex sensor sense flexing in multiple directions. When you select a flex sensor, consider about how much bending it would require to measure.
Choosing a Flex Sensor
When selecting a flex sensor for your project, it is important to keep a few key factors in mind. To begin, consider the range of motion. You should know how many degrees the sensor needs to detect bending. Also, reflect on how strong the sensor is and how well it’ll hold up over time. Check that the sensor is the right size and that it is compatible with the other parts of your project. Considering These Things Helps You Find The Best flex sensor For You
Taking Some of the Guess Work out of Choosing the Sensor for Your Project
The flex sensor that is used must match what is required for your project, so it is vital. Consider which materials you are using, and where will the sensor go. If you are bending metal items, you may need a more durable flex sensor, for instance. It might be helpful to know that if you use softer and more flexible materials, you may want to go with a more flexible and sensitive sensor. Ensuring you have the right sensor for your project will allow you to get the best performance.
Accuracy vs. Sensitivity
When comparing flex sensors it is important for them to be accurate and sensitive. Accuracy refers to how closely the sensor measurements track the actual bending of an object. Much more accurate measurements with a very accurate sensor. Sensitivity indicates the degree of response by the sensor to bending changes. Right towards this issue, a sensitive sensor will detect even a little movement. A flex sensor should be a trade of accuracy and sensitivity depending on your project's requirements.
Installation and Calibration — Tips
Flex sensors only work properly when they are installed and calibrated correctly. Note: When you install a flex sensor, ensure that it is securely attached to the object you intend to measure. Steer clear of anything that may obstruct or affect the sensor’s readings.” It is important to calibrate and obtain accurate measures as well. Calibrate the sensor according to the manufacturer's guidelines and adjust as necessary. It will last longer and run smoother with routine maintenance and calibrations.
