Pressure measurement cell, it comprises the tubular drop and first propulsion element, described indicating device movably is installed in the described first passage and has the indicating device outer wall that is used to indicate the mark of air cavity internal pressure by indicating of surrounding of described sleeve outer wall, this indicating device outer wall limits second channel, described first propulsion element is arranged between described sleeve outer wall and the described indicating device outer wall, thereby described indicating device is suitable for constantly being promoted outwards to move axially from described first passage under the bias effect of described first propulsion element by the pressure in the air cavity, and this causes described first propulsion element to be subjected to displacement, and this displacement is indicated corresponding to the pressure in the air cavity and by the mark that the opening from the bladders outer wall exposes;
First locking member, it can be operated between first latched position and first unlocked position, state first locking member in this first latched position place and engage with described indicating device to prevent that described indicating device from moving axially in described first passage, separate with described indicating device to allow described indicating device to move vertically owing to the pressure in the air cavity at described first locking member of this first unlocked position in separable mode;
The first elasticity charge valve is installed in the bottom that also this second channel is divided into top in the described second channel and is communicated with described air cavity formation fluid, and has first slit of energy auto-closing;
Aerating needle is installed in the described top of described second channel and has by described indicating device outer wall and surrounds and be limited with the pin outer wall that forms the first pin chamber that fluid is communicated with atmosphere, and described Aerating needle and described indicating device can move with respect to described ferrule element together; With
Second propulsion element, between described indicating device outer wall and described pin outer wall, thereby described Aerating needle can move in inflatable bladders from upper position to lower position with respect to described indicating device under the bias effect of described second propulsion element with the external force operation, wherein said Aerating needle stretches into and passes described first slit so that described air cavity is communicated with the described bottom formation fluid of the described first pin chamber via described second channel, when described Aerating needle was disengaged external force, described second propulsion element promoted described Aerating needle and is back to upper position.
