Area medical alert system

for medical gas

The gas alarm box is used to monitor the pipeline pressure of the medical central air supply system and respond to the pressure change through electronic equipment. When the pressure is higher or lower than the set value, the system will automatically give an alarm by means of sound and light, so as to remind the management personnel to respond to the medical center air supply system. Working principle of gas alarm box: The gas alarm device adopts the electric contact pressure gauge to provide the switch signal, that is, the electric contact pressure gauge has two contacts of the upper limit and the lower limit of pressure, and the pressure value indicated by the contact represents the maximum and minimum allowable pressure of the gas pipeline respectively. The upper and lower limit contact values of the meter can be adjusted manually. The electric contact pressure gauge is connected in series in the pressure pipeline. When the pipeline pressure is higher than the upper limit value, the pointer of the pressure gauge will contact with the upper limit contact, thus generating an electrical signal. Similarly, when the pipeline pressure is lower than the lower limit value, the pointer of the pressure gauge will contact with the lower limit contact, also generating an electrical signal, which we call the switch signal. The switch signal is connected to the circuit board of the gas alarm box to form a current pulse - when the high-voltage electric signal is connected, the gas alarm device will start the "overpressure" alarm, and at the same time,
