Fixed sulfur dioxide detection alarm

The SA-3000 series fixed toxic gas detection alarm is an intrinsically safe detection alarm with on-site concentration display (optional) and built-in sound and light alarm device (optional), which realizes 24-hour online monitoring. It is mainly used to detect the concentration of toxic and harmful gases in open or closed environments, and the on-site concentration values can be reflected in real-time to the remote monitoring system.

Characteristics of sulfur dioxide products:

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

On site concentration display with sound and light alarm, two-level alarm can be set 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 explosion-proof rating of Exd II CT6 and protection rating of IP65;

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

There are two output signals to choose from: three wire system (4-20) mA and RS485, compatible with various gas detection and alarm controllers, PL PLC, DCS and other control systems to achieve remote monitoring.

Application areas of sulfur dioxide:

Petrochemical, industrial production, smelting and forging, power, coal mining, tunnel engineering, environmental monitoring, sewage treatment, paint spraying, solid waste treatment

Paper making, biopharmaceuticals, warehousing and logistics, brewing and fermentation, fire protection, gas, waste treatment plants, school laboratories, research centers
