[Instrument Features] What are the core advantages of the Mattress Breathability Tester? — Professional Explanation by HUST TONY

Digital closed-loop control, high-precision testing

Dongguan HUST TONY Instruments Co., Ltd.’s Mattress Breathability Tester features a high-resolution digital controller forming a closed-loop control system. The cylinder’s force output end is equipped with a fatigue-grade tension-compression sensor, and the pneumatic pressure control uses imported SMC electro-pneumatic proportional valves. Control parameters can be directly input via touchscreen to set the cylinder’s output force, enabling precise force loading and stable control. The tester delivers excellent repeatability and high accuracy in test data, meeting multi-level requirements for quality inspection and scientific research.

Real-time force-time curve, with traceable process

The instrument is equipped with a real-time force-time curve display function. During the testing process, the pressure change curve is dynamically presented on the touch screen. The data can be traced throughout the entire process. This not only facilitates technicians to monitor the testing status in real time, but also provides an intuitive and reliable original record for issuing test reports and conducting quality analysis.

Frame-style structure design, with convenient and efficient operation

Dongguan HUST TONY Instrument Co., Ltd.’s mattress air permeability tester adopts a frame-type structure design. The main frame is made of custom thickened aluminum profiles, which is structurally stable and has an attractive appearance. All cylinder groups adopt a sliding movement design, allowing for single-person operation without any auxiliary tools. The frame adjustment part introduces a pulley structure combined with guide rails and bearings, making the adjustment of the loading position smooth and convenient, enabling quick adaptation to different specifications and sizes of test samples, significantly improving the detection efficiency.

Independent control, stable and reliable

Each loading group of the instrument can be independently adjusted and controlled. High-precision force sensors are configured to immediately sense the force values. The air pressure adjustment uses precise SMC proportional valves to precisely control the air pressure and thereby change the loading force values. The independent control of multiple groups ensures that the force values at each loading point are stable and consistent, without interfering with each other. This provides a reliable data foundation for the comparative tests of mattresses of different specifications.

Continuing the race even after power loss, ensuring data security

In actual testing operations, situations such as sudden power outages or emergency shutdowns by humans occur frequently. The mattress air permeability tester produced by Dongguan HUST TONY Instrument Co., Ltd. has a power-off continuation running function: After the power is restored or the machine is restarted, the instrument can continue to operate according to the parameters set before the power outage, and the test data will not be lost due to the interruption of power supply in the middle, ensuring the continuity of the test and the integrity of the results.

Multiple security protection mechanisms

The instrument is equipped with multiple safety protection functions such as cylinder stroke limit protection and sensor force value protection. When the loading exceeds the set range or an abnormal state is detected, the system will automatically trigger the protection action, effectively preventing equipment damage and operational accidents, and ensuring the dual safety of the operators and the instrument.

Flexible and capable of adapting to various sample specifications

For the Mattress Air Permeability Tester manufactured by Dongguan HUST TONY Instrument Co., Ltd., the bottom fixing block can be adjusted freely in position. The electric lifting device enables multi-angle load testing on samples of varying heights. The frame loading position can be easily adjusted to accommodate a wide range of testing scenarios, from small specimens to full-size mattresses. Specification switching can be achieved without replacing main components, meeting the different requirements of incoming material inspection and finished product testing.
