CA-2100-type combustible gas alarm, combustible gas alarm device
CA-2100 series of combustible gas alarm, combustible gas detection alarm by the CA-2100-type combustible gas alarm controller supporting CA-217A-B-type point type for use with flammable gas detectors; the use of advanced computer processing technology;. Inspection work the way; four bus signal transmission: power positive, negative power supply, communication lines LA, communication line LB; real-time rolling circle shows the concentration; Chinese color LCD display, touch keyboard; real-time clock display, power-down can not afford to lose; alarm priority fault , detector fault alarm; alarm to maintain, the first alarm access instructions; using RS485 industrial field bus, lightning protection.
CA-217A-B-type point type combustible gas detectors adopt advanced imported catalytic combustion sensor; performance is stable, sensitive, reliable, long life; anti-toxic properties, anti-jamming; automatic correction of zero, to avoid long-term work measurement error caused by zero drift; concentration of signal output, the controller will issue a warning sound and light alarm.
