Measuring instrument and data, resistance strain gauge This test uses a phenolic resistance strain gauge with a resistance value of R=1208, a sensitivity coefficient of K=2.2, and a measurement area of ​​S=2@4mm2. Measuring instrument and measuring circuit measuring instrument is YJR-5A digital strain gauge. Pressure gauges and test methods and test data The pressure gauge used in this test has an accuracy rating of 2.5 and a range of 250 MPa. The temperature is 203e at room temperature, that is, a working piece and a temperature compensation sheet are used. The rate of expansion and contraction of the tube wall changes linearly with the pressure inside the tube, and has good repeatability. This test is conditionally limited to the use of high-precision pressure gauges, and the size of the strain gauge sensitive grid is too large, so that the accuracy of the experimental results is affected. In software programming, the DSP should be programmed periodically to provide the MAX153 with a start pulse. The frequency of the pulse should be more than twice the frequency of the input signal to ensure that the input signal can be accurately sampled and converted. After the MAX153 conversion is completed, pin 9 (INT) outputs a low level, 74LS245 is gated, and the DSP can read the data by reading the interrupt routine. When the input voltage is 0V, the obtained 8-bit data is 0000001000000000; when the input bit voltage is 5V, the obtained 8-bit data is 1111110011111111; when the voltage of 3V is input, the obtained data is 1001100110011000, and the error is not more than 1.2%. When the input is other values, the error of the obtained value does not exceed this range, and this error range satisfies the requirements of the general communication system. The MAX153 has its own low power consumption and high speed. Only one usage has been introduced, and the benefits of applying it can be seen from here, so it has been widely used in various analog/digital conversion circuits.
The Reinforcement Net have a wide scope of application as reinforce the production of industrial farics, mixed laminar , plasticand / or paper composites and for the structural sppport of polyurethane seats for cars, trains and planes, bed mattress, water filter and air filter.
The Plastic Net is made of Polyethylene (PE), polypropylene (PP), has the clear advantage of being ladder-proof and maintain high dimensional stability throughout the extruded bioriented production process.
