Tension Meter Selection FAQ 

Q1: How should the accuracy index of a tension meter be understood?

A: The accuracy of a tension meter is usually expressed as a percentage, such as ±1%. This means that within the range, the maximum error of the measurement value does not exceed 1% of the full scale (F.S.). For example, for a 1000N tension meter with ±1% accuracy, the measurement error does not exceed ±10N. When selecting, consider the actual required accuracy level; higher is not always better, it must match the application scenario.

Q2: Which is better, non-contact or contact measurement?

A: Both methods have their advantages:

• Non-contact​ (e.g., NSZ series): Does not affect the measured object, suitable for online monitoring, but accuracy is relatively lower.
• Contact​ (e.g., ATL series): High measurement accuracy, but requires contact with the measured object.
  The choice depends mainly on the required measurement accuracy and whether contact with the object is allowed.

Q3: How to determine if a tension meter needs calibration?

A: Calibration is needed under the following circumstances:

1. The specified calibration cycle is reached (usually 6-12 months).
2. The equipment has undergone severe impact or falling.
3. The measurement result shows a significant deviation from a known standard.
4. After use under extreme environmental conditions.

Q4: How should the unit of the tension meter be selected?

A: Unit selection mainly considers:

1. Industry Conventions: Different industries have commonly used units (e.g., elevators often use Kg).
2. Calculation Convenience: Choose units consistent with subsequent calculations.
3. Standardization: Use unified units within the same project to avoid confusion.
   Most tension meters support switching between multiple units and can be flexibly selected as needed.

Q5: How should I select a model when the budget is limited?

A: When the budget is limited, consider the following strategies:

1. Identify Core Needs: Focus on the most necessary functions, eliminate non-core functions.
2. Consider Cost Performance: Choose models with practical functions and moderate prices (e.g., Handheld Wire Rope Tensiometer).
3. Phased Procurement: Purchase a basic model first, upgrade later as needed.
4. Leasing Option: For short-term projects, consider leasing instead of buying.
