Product Name: Electronic Alarm Pressure Gauge Application: Marine Type: General Pressure Gauge Accuracy: 4 Display: Digital Structure: Spring Pressure Gauge Connection Type: Radial Direction Function: Electric Signal-Controlled Installation Structure: Direct Mounting Features of Measurement Medium: General Pressure Gauge Indicating Pressure Reference: General Pressure Gauge Measuring Range: Air Pressure Guage Trademark: zhengze Transport Package: Carton Origin: China Product Description Air breathing apparatus is an important equipment used by fire rescue personnel in dangerous situations. The traditional air respirator air pressure display device is a pointer pressure gauge. When the remaining air volume of the air pressure is lower than 6MPa, the mechanical low-pressure alarm whistle will sound to remind the rescuers of the remaining air volume of the cylinder and need to be evacuated immediately.The intelligent electronic system of air breathing apparatus (ZHD-S3000) not only displays the pressure of the gas cylinder by the traditional pointer, but also dynamically displays the pressure of the gas cylinder through sound and light. You can know the gas volume of the gas cylinder without looking at the pointer. When the gas volume in the gas cylinder is greater than 10MPa, the green light on the front of the pressure gauge lights; when the pressure value is between 6MPa and 10MPa, the yellow light on the front of the pressure gauge lights; when the pressure gauge value is less than 6MPa, the red light and surrounding lights start Blinking, you can see the alarm light in every direction, and at the same time, the high-decibel alarm sound begins to sound to remind the user that there is insufficient air in the cylinder.Features:Convenient installation, small size, and one-handed: just remove the pressure gauge of the original respirator and replace it with ZHD-S3000. The installation can be completed within ten seconds, and the alarm whistle of the original respirator can be retained as needed. The size is the same as the original pointer pressure gauge, so it is comfortable and convenient to wear.Powerful functions: integrated gas cylinder remaining gas volume alarm, fall call for help, temperature alarm (removed), HUD head-up visual wireless transmission, several functions in one.Humanized design, simplified operation: In order to reduce the on-site tedious operation, the product is designed with an intelligent pressure sensing function. The gas cylinder pressure valve opens the gas supply, and the ZHD-S3000 part starts to work without any buttons. At the same time, the optional HUD unit also starts to work within 10 seconds.Low power consumption and long standby time: use one CR123A battery, can stand by for more than 12 months, continuous alarm working time 30 hours.Waterproof and explosion-proof: ExiaIICT4, protection grade IP67.
