Fixed oxygen detection alarm

Adopting advanced imported electrochemical sensors with stable performance, sensitivity and reliability, and on-site display, it helps on-site personnel understand the situation in a timely manner. It has a long service life, small size, over limit current protection, reverse polarity protection, and can work continuously for a long time. It has good resistance to poisoning and strong anti-interference ability, and can output 4-20mA standard signals. It can be used in conjunction with various SA series alarm controls produced by our company, and can also be directly connected to DCS systems with a first level switch quantity. It can be directly connected to the fire control system with a protective circuit at the connection end to prevent misconnection

The fixed toxic gas detector is a detector with no concentration display and sound and light alarm field on site. The detector is mainly used to detect the concentration of toxic gases in open or closed environments, and the on-site concentration values can be reflected in real-time to the remote monitoring system.

• Two power supply modes, DC24V or AC220V, can be selected to meet different on-site requirements;

• There is no concentration display with sound and light alarm on site, and two-level alarm can be set up by oneself;

• Adopting imported electrochemical sensors with high sensitivity, good linearity, long lifespan, and stable performance;

• Circuit optimization design, equipped with reverse polarity protection and current limiting protection, can effectively prevent unnecessary damage caused by wiring errors;

• There are one or two passive relay contacts that output signals to drive external devices such as fans and solenoid valves;

• Having an explosion-proof rating of Exd I 丨 CT6 and a protection rating of 丨 P65;

• Shell material: die cast aluminum+304 stainless steel (sensor cover);

• There are two output signals to choose from: three wire<4~20) mA and RS485, compatible with various gas detection and alarm controllersControl systems such as PLPLC and DCS enable remote monitoring
