To increase the connection concentricity and the torsion bearing capability of the cylindrical tension/compression force sensor

a new high-concentricity cylindrical force sensor is developed.In this sensor

screw structure and adapted rod and hole are used to connect with the corresponding joined components

the adapted rod and hole are grinded to assure the high-concentricity of the connection.Two guide pins mounted between the shell and the elastic element

the axial sliding of the elastic element is guides and the torsion that otherwise exerts on the elastic element is avoids.The rating load of the sensor is 5 000 N

the utmost overload is 120 %

the sensitivity is better than 1.0 mV/V

and the service temperature is room temperature.Calibration on the sensor indicateds that the gross error of the sensor is below 0.2 % of the rating output.
