The F15L-1 annular strain force sensor is designed as a hollow structure with a central through-hole diameter of 15mm for shaft insertion. It can be connected through threads on both sides, making integration very easy. It adopts special strain gauge technology, covering a wide range of angles, so it is insensitive to bending moment height and has high stiffness, making it suitable for both high dynamic and static measurement tasks. The F15L-1 force sensor is made of high-quality stainless steel or alloy steel, with high strength, good rigidity, and strict processing technology to ensure durability and high load-bearing capacity. The use of high flexibility, tensile strength, anti-interference cables and sensor internal design for anti-interference can greatly prevent electromagnetic interference.
