Type: DSJYB-1


The combination of a high-voltage gauge and a residual alarm can both indicate the air supply pressure of the cylinder and give an audible alarm when the cylinder reaches the design approval pressure. The gauge range is 0-40MPa, the working pressure of the cylinder is 27-30MPa and the alarm pressure 5-6MPa is marked with green and red areas, respectively. When the pressure of the cylinder drops to 5±0.5MPa, the residual gas alarm will emit a continuous sound of 90dB to remind the user that the gas source will be used up and it is necessary to evacuate the site as soon as possible. For a cylinder with a volume of more than 5L, the gas source for the cylinder can be used by the wearer for 5-8 minutes.  


Clear display

The pressure gauge data is clear and has night vision function. It can be clearly checked even at night.

Rubber protective cover

The thick rubber protective layer can avoid accidental collision or damage.

Sound alarm

The pressure gauge is connected with the alarm whistle. When the cylinder pressure reaches the alarm value of low pressure, the mechanical pressure gauge will give a sound alarm.

Simple maintenance

Seismic protection and specially designed solid enclosures enhance the safety factor of mechanical pressure gauges in transportation and operation.
