A round force sensor from Seeed Studio is a durable, precise, and compact force sensing solution for applications where contact needs to be made with curved surfaces. This force sensor features precise measurement, high accuracy, and linearity. It provides an analog output, allowing the user to measure pressure between 0-10V or 4-20mA. This range can be increased by multiplying the output. The force sensor is suitable for use in applications such as robotics, measuring police baton force, and manufacturing. It supports a variety of shapes and materials, and can provide quick detection and reaction times.
