Cornell tester

Standard basis: ASTM project

The pressure applied to the mattress is read by a pressure transmitter, with a pressure range of 300KG

2. Adjust the stroke of the push rod so that the maximum force applied to the mattress is 1025N, and the minimum force is 22N

3. The stroke speed of the push rod can be adjusted, about 100 cycles per minute

4. Suitable for mattresses with a maximum size of 2.2 M X 2 M

5. The computer program compiles a complete test report based on the data from the pressure transmitter and position transmitter

6. The computer synchronizes monitoring instrument measurement data and can output Excel data reports

7. Automatic adjustment of height loss in 7 stages: 200, 6000, 12500, 25000, 50000, 75000, 100000

8. Configuration: One indentation test head, one 200kg force sensor, and one measuring tool

2、 Instrument features:

1. This mattress testing equipment complies with the latest national testing standard ASTM F1566; Users can choose between automatic and manual testing modes, which makes the testing data more accurate and greatly reduces the workload of testing;

2. The appearance is beautiful and generous, and the body is seamlessly welded with channel steel (the height measuring device adopts an aluminum alloy frame structure), and the sheet metal is electrostatically sprayed. Fully concealed wiring greatly improves safety; The bearing surface is made of stainless steel plate, which has a smooth surface and is convenient for loading mattresses; All steel plate base, no need to drill holes to fix the ground, fully ensuring that the instrument does not move or shake during operation.

3. Adopting a gantry style mechanical structure, using high-precision variable frequency motors and low-noise high-precision linear guides as transmission components, the mechanical strength and stiffness of the entire machine are improved, the service life and accuracy of detection data are increased, and the operating noise is effectively reduced

4. The instrument prints out the test results through a printer, increasing the persuasiveness of the test data.

5. Data protection: Automatic power outage saving (data can be automatically saved after power outage).

Control system:

1. The touch screen is equipped with a PLC and has a memory function for stopping and turning off power;

2. Equipped with breakpoint protection (alarm) function, deceleration motor+frequency conversion control;

3 manual pressure regulation, SMC precision pressure gauge;

4. Counter stop/power off memory function;
