Part is connect by signal wire with circuit board.
As a further improvement of the above technical scheme, the display device includes thermometer and vacuum meter, the temperature
Degree table and vacuum meter pass through conducting wire respectively and connect with circuit board.
As a further improvement of the above technical scheme, it is set between the vacuum air inlet pipe and outer housing and vaccum case
There is sealing device.
As a further improvement of the above technical scheme, waterproof insulating layer is equipped with outside the circuit board.
As a further improvement of the above technical scheme, it is recessed to be equipped with a-circle-by-a-circle annular for the outside of the vacuum air inlet pipe
Slot, the junction of two annular groove are equipped with the sealing ring of sheet.
As a further improvement of the above technical scheme, the outer housing uses aluminium alloy or stainless steel material.
The beneficial effects of the utility model are: annular groove and its flap seal circle in vacuum air inlet pipe with connection
Play the role of sealed connection between equipment, prevent gas leakage, pressure sensor experiences pressure, is transmitted on circuit board, as a result shows
Show on vacuum meter, the temperature element inside vaccum case, temperature sensing can be carried out to the temperature change of sensor, and pass through
Temperature results are reacted on thermometer by circuit board, and stability height and the accuracy for improving sensor are high, vacuum meter and temperature
It spends table and shows testing result, it is as a result more intuitive, it uses more convenient.
