Force Sensors

Force Sensors are specialized devices designed to detect and react to the presence or changes in pressure applied to their actuator. These actuators can take various forms, such as a ball, button, diaphragm, flat membrane, plunger, or pushbutton. The sensors employ different technologies, including force sensing resistors, load cells, and resistive sensors, to accurately measure the force exerted on them.

Force Sensing Resistors (FSRs) are flexible sensors that exhibit changes in resistance when subjected to pressure. By measuring the variation in resistance, FSRs can determine the force applied to the actuator. Load cells, on the other hand, are robust sensors that directly measure the force. They employ strain gauges that deform under the applied force, causing a change in electrical resistance that is converted into an output signal. Resistive sensors encompass various principles, such as piezoresistive or capacitive, and utilize resistance changes to detect force.

Force Sensors have operating force ranges spanning from 0 to 1500 newtons (N), 0 to 22,680 kilograms force (kgf), or 0 to 50,000 pounds (lbs.). This broad range ensures compatibility with diverse applications. The sensors offer multiple output options, including analog voltage, resistive, ratiometric, and voltage outputs. The choice of output depends on the specific requirements of the system and its integration with other components.

These sensors are primarily used in industrial settings, where precise force detection is crucial. They find application in various industries, including manufacturing, robotics, automation, aerospace, and automotive sectors. Industrial Force Sensors play vital roles in process control, quality assurance, safety monitoring, and accurate force measurement tasks. Their reliability, accuracy, and compatibility contribute to enhanced operational efficiency, productivity, and safety in industrial environments.
