The measurement accuracy of the force sensor is highly dependent on the installation conditions. Improper installation conditions can adversely affect measurement accuracy, dynamic performance of the measurement chain, and sensitivity of the electromagnetic field.
How to properly install the force sensor

In general, load cells cannot be calibrated in the application, while force sensors do not. In order to obtain better and more reliable measurement results, the most important thing is to achieve the calibration installation conditions as much as possible in actual use, and the deviation range should be within the technical requirements.

1. The force in the force direction The force on the sensor needs to be applied as much as possible in the direction of measurement. First, once the applied force and force sensor measurement directions are inconsistent, the measurement error will increase. There is an angle between the force measurement direction and the applied force, and the sensor generally does not measure the lateral force.

2. Influence of lateral force, bending moment and torque
a. Lateral force The lateral force is perpendicular to the force applied in the direction of measurement. These lateral forces are generally due to their own weight or due to the application of an angle to the load. And a bending moment is formed (because little lateral force acts on the mounting height of the strain gauge). An additional error will result depending on the lateral sensitivity. If the lateral force is 10% of Fz, the direction of measurement is generally less than 1% of Fz.

b. bending moment China Hardware Business Network
When the sensor is installed horizontally, its own weight and mounting accessories will produce bending moments. In addition, eccentric loading will also produce bending moments. The rotationally symmetric force sensor compensates for bending moments at multiple measuring points distributed around it and is therefore very insensitive to bending moments. The force sensor U10M uses a bending moment queuing technique with a bending moment effect of only 0.01%.

An oversized bending moment damage force sensor. In addition, bending moments tend to occur along with lateral forces, which can add additional load to the sensor.

c. Torque For the internal thread of the tension force sensor or the bolt structure sensor installation process, it is very important to connect with the appropriate torque. However, the maximum torque cannot be exceeded because the sensor will be damaged if the limit is exceeded.

d. Interaction of Torque, Lateral Force and Moment The ultimate load is associated with the rated load of the sensor. The sensor may be affected by a parasitic load or by multiple parasitic loads. If they work at the same time, the sum cannot exceed 100%. For example: 50% allowable torque, 40% allow bending moment plus 10% allow lateral force.
