Brief introduction: The instrument is dedicated to detect helmets shock absorption performance and puncture resistance. Determination of helmet shock resistance, will wear a good helmet special Settings on the high sensitivity of the sensor head model, the quality and use 5 kg of hammer impact from the height of 1 m, and the high sensitivity of force sensor to measure the impact moment of force value, on the basis of judging helmet shock absorption performance. For rubber industry, plastics industry, inspection department and scientific research units to use. Features: 1. The impact hammer and puncture hammer replacement operation is simple. 2. Cardan positioning, ensure the impact hammer and puncture hammer accurately hit a fall on the helmet. 3. Professional impact sensor has high precision, range 0 ~ 20 kn, full range within the scope of plus or minus 2.0% 4. LED digital display, accurate to 1 n, automatically save the most value. Technical indicators: Die head: completely in line with GB/T 2812-2006 appendix A of the helmet test method standard. Bench: ability to hang and release of drop hammer impact hammer, puncture. Drop hammer impact hammer: quality of 5 ~ 5.01 kg, hammer head hemispherical, 96 mm in diameter, material of 45 # steel. Puncture hammer: quality for 3 ~ 3.05 kg, puncture part of the cone Angle 60 °, cone tip 1 mm in diameter, length of 40 mm, maximum diameter 28 mm, hardness HRC45. The impact of the two hammer after installation completely accords with the standard. Force transducer, measurement range 0 ~ 20 kn, frequency corresponding minimum 5 KHZ, dynamic force sensor. Base: can have impact strength, strong force transducer installation. Electricity display device: when the puncture cone die contact, form a closed loop circuit, signal sound and light alarm prompt. Drop height: 1000 mm. Working power supply: AC220v, 50 hz, 50 w. Weight: about 30 k ɡ.
