FAQ
1. Q: Which benefit of the 20mm diameter design is the greatest?
A: The compact 20mm button-style design of the sensor makes it possible to install it in very tight places where there is no room for a regular load cell. Therefore, it can be embedded in machinery and test fixtures.
2. Q: For what type of applications can the use of the <0.03mm deflection feature be anticipated?
A: Minimizing deflection is very critical for such applications as the precision assembly, robotic end-effectors, and testing jigs, where the large displacement may lead to process or measurement errors.
3. Q: Which capacity should I choose between 10N and 10kN?
A: It should depend on your maximum force: 10-100N for delicate assembly; 500N-2kN for normal industrial monitoring; 5-10kN for heavier press and machinery.
4. Q: What are the reasons why the natural frequency >10kHz is so important?
A: The high natural frequency allows the sensor to be applied for accurate dynamic force measurement, and it will not have resonance problems during high-speed, impact testing, and automation applications.
5 Q: How do we interpret the wide temperature operating range (-40°C to +120°C)?
A: It means that the sensor is suitable for use practically anywhere. Moreover, it is able to endure weather conditions, for example, outdoor, automotive testing, and industrial processes with temperature changes.
