Product introduction:
QB2000F wall-mounted gas detector (hereinafter referred to as the detector) is a fixed instrument that can continuously detect the concentration of gas in the operating environment.Applicable to power, electronics, metallurgy, chemical industry, petroleum, coal, mines, railways and medicine and other occasions where gas leakage may occur.
The detector is a free diffusion method to detect the concentration of gas, using imported sensors, with excellent sensitivity and repeatability;Large LCD screen displays the concentration value of the leakage gas in real time, and immediately starts the acousto-optic alarm signal or drives the exhaust air system beyond the preset alarm point; MA signal of international standard (4~20) can be directly connected to the DCS system of the factory. RS485 digital signal is connected to the upper computer of the factory.The instrument adopts embedded micro-control technology, the whole Chinese menu operation is simple, the function is complete, the reliability is high, the entire machine performance is reliable.
The detector can be divided into explosion-proof type and non-explosion-proof type according to the application situation. Explosion-proof type: the machine did explosion-proof processing, has reached the Exd Ⅱ CT6 Gb level, can be directly connected explosion-proof bobbin, installed in the presence of the places where explosive dangerous gas and steam. Non-explosion-proof type: it is forbidden to install in the place where there is explosion risk, using plug + gasket + rubber sleeve lead.
