Product Name: Zhd-X20 Respirator Backplane Hud Launcher 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 product description:Without changing the configuration of the pressure gauge for air calling, the electronic pressure sensor is used to change the pressure signal into an electrical signal, and the current pressure range of the gas cylinder is displayed in the form of light, and the data is wirelessly transmitted to the placed in the mask Pressure head-up display device (HUD) device, HUD displays the usage of the gas volume of the gas cylinder through LED lighting, and promptly informs rescuers to avoid dangerous situations caused by rescuers who cannot hear the alarm sound under complex scene conditions .Features:Powerful functions: integrate digital pressure data collection, temperature data collection, HUD data wireless transmission and other functions in one.Humanized design simplifies operation: In order to reduce on-site tedious operations, the product is designed with an intelligent pressure sensing function. The gas cylinder turns on the gas supply, and the automatic start-up work does not require buttons. At the same time, the equipped HUD unit starts working within 10 seconds.Low power consumption and long standby time: use 2 batteries of size 7, stand by for 1.5-2 years, work continuously for more than 100 hours (when connected to HUD)
