Fengyun brand DYM3-2 mining air box pressure gauge 920-1340hpa Working principle of empty box pressure gauge:The working principle of an empty box pressure gauge is to use an empty box group that moves axially with changes in atmospheric pressure as the sensing element. It drives the pointer through a rod and transmission mechanism to indicate the atmospheric pressure value at that time.
3、 Empty box pressure gaugeUsage:
1Please place the empty box pressure gauge horizontally when using.
2Please lightly tap the outer shell or surface glass of the empty box pressure gauge with your fingers to eliminate friction in the transmission mechanism.
3When observing, the pointer overlaps with the mirror pointer, and the value pointed by the pointer is the air pressure indication value, with the reading accurate to one decimal place.
4Read the temperature reading on the empty box pressure gauge to one decimal place.
