background :

Toxic gas alarm includes detector and alarm control host. People usually use it in the petrochemical industry where toxic gases exist, such as petroleum, gas, chemical, and oil depots. We use it to check for leaks in dangerous situations inside and outside the room. The toxic gas alarm is an important instrument to ensure production and personal safety.

When we use the toxic gas alarm to monitor the  gas, the detector converts the gas signal into a voltage signal or current signal and transmits it to the alarm surface, and the instrument shows the percentage concentration value of the lower limit of the toxic gas explosion.

We found that when the toxic gas alarm monitoring gas concentration exceeds the alarm set value, it will send out an audible and visual alarm signal. At this time, the staff on duty will take timely safety measures. Therefore, we prevent explosion accidents.

Notes on application :

Once the fixed equipment of the toxic gas alarm is in place, it is not easy to change. We should consider the following points in specific applications.

(1) We need to identify the leakage point of the monitored equipment. And then analyze factors such as leakage pressure and leakage direction.  In addition, we draw a probe position distribution map. And, users are divided into three grades: I, II, and III according to the severity of the leak.

(2) We are based on the detailed factors such as airflow, direction, and wind direction of the location. Thus, the direction of leakage of the toxic gas can be discriminated.

(3) According to the density of the leaking gas, we can form a three-dimensional movement trend map of the leakage according to the air movement trend, and make an initial set point plan in the downstream position of its movement.

(4) We can study whether the leakage is micro-leak or jet-like. If it is a slight leak, then the position of the set point should be close to the leak point. If it is a jet leak, stay away from the leak point. Based on these circumstances, the user draws up a final set-up plan. Therefore, we can budget for the quantity and type of purchases required.Accurate's carbon monoxide sensor can effectively monitor.
