Turn on 220V AC power, at this time the power indicator light, yellow light flashes, about 2 minutes, the yellow light goes out, indicating that the flammable gas alarm warm-up end, began to monitor the environment, this time the safety valve is in the open state, When the gas leak reaches the alarm concentration, the red light of the alarm is on, the buzzer starts to sound and the safety valve is closed, and the air source is cut off; when the indoor gas concentration is lower than the alarm concentration, the red light goes out and the alarm sound stops. After the leak has been removed, lift the handle on the upper end of the safety valve to lift the safety valve in the open state and restore the air supply. The alarm will be monitored again.
In terms of sensors, one of the frequently asked questions is: "What sensor is good?" Of course, this question cannot be clearly stated in a sentence or two. Each sensor has its own performance and limitations, so the adaptability of a given sensor depends heavily on the application during use. Therefore, in order to select a correct sensor, it is first necessary to determine the application requirements. The manufacturer provides a rough calibration of the sensor. 1. The sensor will be designed as a small, coarse-looking small box. The sensor must be suitable for hazardous locations and harsh environments, and it must be explosion-proof. The sensors must be cost-effective, designed for use within industrial production areas, and the cost of placement is reasonable. 2. For portable instruments, the instrument has reasonable energy consumption, and the power source selected by the instrument is a battery that is easily available on the market. The instrument is small, convenient and easy to carry. It is very safe to use in an industrial environment. Due to use in hazardous areas, the instrument must have a safety certificate.
