|product name:||1-4CH 4-20MA alarm control host|
|Measurement object:||Gas in the air|
SK-6200 gas detection alarm has the characteristics of high stability, high accuracy and high intelligence. The external control ports are abundant. The user can freely choose the type and connection port of the connected sensor, and can perform field detection and alarm through simple settings. . The current version of the system has integrated alarm speakers, 4 channels of 4 channels alarm control normally open normally closed control terminal and 1 channel of all channels normally open normally closed control terminal (users can easily connect external power alarms or other exhaust valves and other external controls device).
SK-6200 gas detection alarm system is mainly used in situations where flammable or various toxic gases need to be detected, and the numerical indicator of the gas to be detected is displayed. When the index of a certain gas on the site does not meet the set standards, the system Will automatically perform a series of alarm actions, such as alarm, exhaust, trip, etc. (different according to different settings of the user)

1-4 way 4-20MA alarm control host application:
Petroleum and petrochemical, chemical industry, smelting plant, steel plant, mining plant, thermal power plant, pharmaceutical production workshop, environmental monitoring, fire alarm, sewage treatment, gas station monitoring, security inspection, inspection and quarantine, etc. It is mainly used to monitor the indoor and outdoor detection of gas leakage. When there is a gas leak, the detector will detect the leakage information and display the leaked gas concentration in real time, and transmit the relevant data to the controller in time. When a certain concentration is reached, the controller It will remind the user that a gas leak has been detected, and the associated equipment and related personnel take relevant measures, which are important instruments to ensure the safety of the environment, production, and life and property.
