Introduction: Gas alarm gas leak detection alarm device. When the industrial environment flammable or toxic gas leaks, gas When the body alarm detects the gas concentration reaches the critical point set by the explosion or poisoning alarm, the alarm will send an alarm No. to remind the work to take safety measures and to drive exhaust, cut off, sprinkler system to prevent the explosion, the fire, in Drug accidents, so as to ensure safe production. Industrial fixed gas alarm alarm controller and detector composition, control The device can be placed in the duty room, mainly for the control of the monitoring points, the detector is installed in the gas leaks most easily, its The core component is a built-in gas sensor that detects the concentration of gas in the air. Gas alarm is divided into household gas alarm and industrial gas alarm. Home gas alarm is seized Measured gas and gas leaks. Industrial gas alarm is the detection of ammonia, nitrogen dioxide and other industrial gases. Features: Test object: combustible gas in the air Detection range: (0-100)% LEL Detection method: natural diffusion Working methods: fixed continuous work The nature of the sensor: catalytic combustion Explosion-proof form: Flameproof Technical Parameters: Working voltage: AC220V ± 15% 50Hz Ambient temperature: -20 ℃ ~ +60 ℃; Humidity range: <90% RH Maximum power consumption: <3W / road Alarm point: adjustable Wiring: 3-wire system (two power lines, a signal line) Alarm mode: audible alarm (sound pressure level at 1 meter above 65dB); Alarm output: two channels per channel capacity of 2A / 250VAC normally open passive contact output Transmission distance: up to 1500m Minimum display value: 1% LEL Response time: 90% response does not exceed 30 seconds Recovery time: no more than 90 seconds (no gas back to zero time) Sensor life: generally more than two years (bad working conditions of the probe, the sensor will shorten the life) Connection method: can be directly connected with the thread explosion-proof hose or connected by simple method Connection cable: three-core cable with shielded cable (recommended shielded cable) Explosion-proof grade: ExdIICT6 (Tamb = -40 ° C to + 75 ° C);
