工业气体controler系统

industrial gas controler system The ZX-730 flammable gas examination warning controller (hereafter refers to as controller) as the intelligence warning controller, it with has the explosion-proof performance SC610 combustible gas detector (to hereafter refer to as detector) to coordinate the use. The controller is being advantageous for the observation and the maintenance place of safety, the detector signal gives the controller through 485 main line way transmission, the controller may demonstrate the current channel number, conditions and so on channel density as well as warning or expiration. When the density value surpasses the warning predetermined value, the controller may send out the acousto-optic warning, and sends out the control signal, prompts the operators, thus avoids having each kind of safety incident. The ZX-730 flammable gas warning controller widely uses in chemical, the petroleum, the metallurgy, the fuel depot, the liquid gas station, the painting work, the fuel gas losing matches and so on flammable gas to have, the storage, the use and so on indoor outside easy spillage risk place. the Z X-212 flammable gas warning controller's design, the manufacture conform to GB16808-1997 "Flammable gas Warning Controller Specification And Testing method" People's Republic of China national standards and corresponding regulations. type ZX-730 range of using voltageAC 220V±20% channel capacity /pipe capacity100 wire system485bus-mode temperature -10°C 55°C relative humidity 93%RH range of sound pressure>75dB/m preparation electricity working time >2 hours concentration of alarm25%LEL 50%LEL concentration of alarm error < ±3%LEL alarm method sound and light alarm, liquid crystal Structural Dimension 520mmX360mmX100mm perform standard GB16808-1997 MPU with kind of functions: real-time check of data,fault detecting,power management,alarm display,alarm indication ,relay outputs etc,1 signal for RS-485 with capacity of 16pcs digital detectors, simulate for channel and digital channel can be used togetther,It can manage different gas detectors,different level and diffferent digital unit detectors,Intelligent system:easy zero calibration,free relay output,4 passive relay contact output ,linkage programmer ,easy to install w
