Frequently Asked Questions about Force Sensors

Q1：What is a shaft pin sensor and where is FA9133 used?

A: A shaft pin sensor replaces traditional pins in mechanical structures to directly measure force. The FA9133 is widely used in cranes, port machinery, industrial automation, marine, and aerospace applications.

Q2：Does FA9133 support unidirectional or bidirectional measurement?

A:The FA9133 supports bidirectional force measurement, allowing detection of both tension and compression.

Q3：What is the accuracy of FA9133?

A:The combined accuracy is ≤0.03%, with excellent linearity (≤0.03%), repeatability (≤0.03%), and hysteresis performance.

Q4：What is the protection rating and environmental capability?

A: The FA9133 has an IP65 rating and operates reliably in temperatures from -20°C to 60°C, suitable for harsh environments.

Q5：What should be considered during installation?

A:

• Ensure proper alignment with mounting holes

• Avoid side loads and impact forces

• Install according to load direction

• Secure properly to prevent loosening
