1. The role of sf6 gas density meter and density relay
The so-called density refers to the mass per unit volume of a specific substance under specific conditions. The SF6 pressure gas in the SF6 circuit breaker is sealed in a fixed container. It has a certain density value under the rated pressure at 20℃. Within the range of various allowable conditions for the operation of the circuit breaker, although the pressure of SF6 gas changes with temperature, the density value of SF6 gas is always the same. Because the insulation and arc extinguishing performance of SF6 circuit breakers depends to a large extent on the purity and density of SF6 gas, the detection and density monitoring of SF6 gas purity is particularly important. If an ordinary pressure gauge is used to monitor the leakage of SF6 gas, it will be difficult to distinguish whether the pressure change of SF6 gas is caused by the actual leakage or the change of the ambient temperature. In order to achieve the purpose of frequent monitoring of density, SF6 circuit breakers should be equipped with SF6 gas density meters or density relays. The SF6 gas density gauge meter is for monitoring, and the density relay is for control and protection.

SF6 Gas Leakage Monitoring System - Quantitative Alarm
The SF6 gas leakage quantitative alarm system is based on the current situation in which the power system emphasizes safe production, and is an intelligent online detection system designed and developed to provide personal health and safety protection for the personnel in the power distribution device room where SF6 meter is installed. The system mainly detects the SF6 gas content and oxygen content in the ambient air. When the SF6 gas content in the environment exceeds the standard or lacks oxygen, it can alarm in real time. At the same time, the ventilation system is automatically turned on, with temperature and humidity detection, working status voice prompts, remote alarm, Historical data query and many other rich features.
YiWhip Cream Chargers and Dispenser
N2O (nitrous oxide) is a colorless non-flammable gas that is widely used as a propellant in the food industry. With its bacteriostatic properties (inhibits the growth of bacteria) and its slightly sweet odor, it is used worldwide as a food propellant especially in making Whipped Cream. This versatile gas is the key ingredient found in whipped cream gas chargers wholesale, which are essential tools for achieving that airy texture in whipped cream.
