Embodiment Construction
[0034] The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0035] The invention provides a device with a pressure sensor for testing the compressive stress relaxation of rubber at room temperature and high temperature, such as figure 1 As shown, it mainly includes the following parts: lower plate 1 , limiter 2 , upper plate 3 , pressure sensor 4 , sensor lead 5 , indenter 6 and flange 7 .
[0036] like figure 1 As shown, the upper plate 3 is placed flat above the lower plate 1 , and the lower plate 1 and the upper plate 3 are fixed together by the left and right limiters 2 . The pressure sensor 4 is located between the lower plate 1 and the upper plate 3 , one end of the pressure sensor 4 is fixed at the center position of the downward face of the upper plate 3 , and the other end is fixed with a pressure head 6 . The pressure sensor 4 is connected with the external data display instrument through the sensor ...
