Pressure gage & Alarm whistle

Mounted on the chest, it ≥90 dB alarm sounds, the user can easily hear the alarm sound in a noisy environment, night vision gauge with explosion-proof 、waterproof and shockproof function.


Main performance

Pressure gage reading: 0-40MPa, with safety opening.

With fluorescence function, the area of 0-5MPa marked in red.

Working pressure: 30MPa

The thimble in the alarm whistle is fixed in the spring by the high pressure air, which is transported by pressure regulator and high-pressure pipelines, when opening the valve of gas cylinder. The thimble is for sealing, it can prevent the medium-pressure air into the alarm whistle and hence, the whistle won’t alarm.

When the pressure in the gas cylinder is below 5.5±0.5MPa,the thimble detach the sealing position

under the action of the string, the medium-pressure air enter into the alarm whistle at the speed of 5 L per minute. And then, the whistle alarms.

Work function

Work pressure of the alarm whistle: 5.5±0.5MPa

The whistle will alarm until the air exhaust.

Air consumption: 5 L/ minute

Sound level: 90db

Frequency: 3800HZ
