Product details
BK-4A spoke type force/weight sensor

·The elastomer is a spoke, spoke, and hard core flat membrane structure with a low external height, used for measuring tensile and compressive forces, and has strong resistance to deflection and lateral forces.
·High precision, good symmetry of tension and compression output, stable and reliable performance, wide range of measurement, easy installation and use.
·Tension compression bearing.
·Suitable for testing various load forces, various tensile and compressive tests, electronic scales, and industrial automation measurement and control systems
