First, the principle of ring pressure side pressure meter: Place the sample test fixture between the upper and lower pressure plates, and then apply the specified speed. When the lower pressure plate is compressed upward, the load on the upper end of the upper pressure plate senses the pressure and converts the pressure into a voltage signal. The output is sent to the display for analysis and the pressure value is displayed on the power display. Second, the use of standards: The design of this instrument meets the requirements of TAPPI-T472, JIS-P8126, GB/T2679.9 and other standards. Third, the characteristics of the ring pressure side pressure meter: This machine is sensitive to high-precision sensors, and the strength of the sample is digitally displayed through software analysis. Fourth, the main technical parameters of the ring pressure side pressure gauge: Capacity: 10, 20, 50, 100, 200kg; Degree of decomposition: 1/100,000; Accuracy: ≤0.5% Display mode: LCD display Press plate: 100×100mm or depending on the diameter of the flat sample; Compression spacing: 80mm; Plate parallelism: ±0.05mm Ring pressure sample: 152.4 × 12.7mm Side pressure sample: 25 × 100mm Test speed: 12.7mm/min Horsepower: 1/8HP; Dimensions: 570 × 415 × 730mm Weight: 48kg; Power supply: 1∮, AC220V, 1.5A Five, ring pressure side pressure testing machine equipment structure diagram: 1. Power sensor: When the upper platen moves downward, the inductive paper or cardboard is resistant to pressure and transmitted to the power display. 2. Upper platen 3. Lower platen 4. Moving the beam: The beam is driven by a high-precision ball screw to move the upper clamp up and down, and the force sensor is installed between the beam and the upper clamp. 5. Control panel 6. Base
