Embodiment Construction
[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0026] Such as figure 1 As shown, a calibration device for an ultra-high temperature pressure sensor includes an ultra-high temperature temperature control device 5, a high temperature resistant pressure tube 4, a pressure controller 8, a mechanical pump 9, a nitrogen cylinder 10, a sensor tool 3, a heat dissipation tool 2, an acquisition System 11, temperature measuring part 12;
[0027] The temperature control of the ultra-high temperature pressure sensor calibration device is achieved by passing the high temperature resistant pressure tube 4 through the ultra high temperature temperature control device 5, that is, the pressure controller 8 connected to one end of the high temperature resistant pressure tube 4 is located in the ultra high temperature temperature control device 5, and is at room temperature; the sensor tooling 3 connected to the other end o...
