BIFMA X5.4 EN1728 Chair Seat and Back Durability Tester Comprehensive Durability Test Machine

Product Introduction

The machine is designed to test seating and back by specified load block with setting force and speed, to assess chair seating and back durability.Suitable for testing seat products, such as office chair, Single Seat, stool, etc.

Product Feature

1, The 2-channel pneumatic closed-loop single-chip microcomputer control system developed by the factory can optionally control the output force or displacement mode of the cylinder, and the optional two-channel cylinder to do synchronous or asynchronous working mode according to the timing.
2, In the selection of cylinder output force control mode, the force is closed-loop control.
That is, the delay is triggered only when the current value of the loading force reaches 95% of the set value (which can be modified in the background), and the current value can be kept within ±3% of the set value (the standard requirement is ±5%).
3, In the mode of selecting the cylinder output position, the displacement is controlled by moving a magnetic sensor attached to the cylinder surface.
4, Touch screen input test parameters and output test results, real-time display and track each section of force ~ time values and curves.
5. The system has low pressure detection and breakpoint stop function, stop and power memory function.
