About HMI Based Back Strength Test Panel
Chair Back Strength Tester Panel Working Description
A Chair Back Strength Tester is used to test the strength and durability of a chair backrest by applying a specified force repeatedly or for a fixed duration, as defined in standards such as ANSI/BIFMA X5.1. The machine typically uses a PLC, HMI, load cell, servo motor or pneumatic cylinder, and safety sensors to automate the test process.
Main Functions of the Control Panel
The HMI/Panel usually includes the following settings and indicators:
Test Parameters
- Set Load (N or kgf) Required force to apply to the chair back.
- Hold Time (sec) Duration to hold the force during static testing.
- Cycle Count Number of cycles for durability testing.
- Test Speed Cycles per minute.
- Stroke Length Forward movement distance of actuator.
- Return Delay Delay before returning to home position.
