online toxic gas detector KB-501SG

Gas detector KB-501SG is a new type toxic gas detector which used advanced electrochemical sensor and microcontroller, employed sophisticated SMD technology. It has following advantages: good repeatability,high resistance to humidity-temperature jamming, long performance life and simple operation. It is applied to inspection for toxic gas concentration in industrial environments.KB-501SG can translate the appointed gas concentration signals into digital signals display. Three-wire system 4 20mA electric current signals output, with long-distance transmission and high anti-interference capacity. In addition, it has two-stage alarm function with acoustic and light signals.Common applications is gas safety inspection and alert for industrial scene, such as petroleum refinery, chemical plants, LPG stations, boiler rooms, gas stations, paint spray booths, etc.Features• Imported electrochemical sensor;• Intrinsically safety circuit design;• High brightness LED digital display, clear and direct;• Timely alert with acoustic and light alarm signals;• Three-wire system 4 20mA standard signals output and long-distance transmission;• Possible to connect to DCS system directly;The probe has following advantages: high sensitivity, quick-response capacity, long performance life and short polarization time.• With a manual controller (optional units) used for adjustment of parameter;• Function of infrared remote control operation (remote-control is optional units).Technical SpecificationsApplicable Gas Toxic gas (CO, H2S, etc) Detecting Range Refer to the gas parameter list Alarm Threshold Refer to the gas parameter list Working Current ≤32mA Working Voltage 16 30V DC Power Consumption <1 W Display High brightness LED display Output Signals Three-wire system 4 20mA standard signals output Alarm Signal Acoustic and light signals alert Installation Means Wall mounted Transmission Distance ≤1000m Explosion-proof Type Explosion insulating Explosion-proof Index Ex d IIC T6 Protection Grade IP65 Gas Parameter listGasProductDetecting RangeResolutionAlarm Threshold (two-stage)Low / HighNH3NH3 detector(0 100)PPM1 PPM25 PPM / 50 PPMO2O2 detector(0 30)%VOL0.1%VOL19.5%VOL / 23.5%VOLCOCO detector(0 1000) PPM1 PPM35 PPM / 200 PPMH2SH2S detector(0 100)PPM1 PPM10 PPM / 15 PPMH2H2 detector(0 1000) PPM1 PPM35 PPM / 250 PPMCl2Cl2 detector(0 20) PPM0.1 PPM5 PPM / 10 PPMNONO detector(0 1000) PPM1 PPM25 PPM / 50 PPMClO2ClO2 detector(0 10) PPM0.1 PPM0.5 PPM / 1.5 PPMHCNHCN detector(0 100) PPM1 PPM5 PPM / 10 PPMSO2SO2 detector(0 500) PPM1 PPM10 PPM / 50 PPMC2H40C2H4O detector(0 100) PPM1 PPM5 PPM / 10 PPMC3H3NC3H3N detector(0 100) PPM1 PPM5 PPM / 15 PPM
