The carbon monoxide detector uses a carbon monoxide sensor to convert the concentration signal of carbon monoxide gas in the air into a weak current or voltage signal, and then amplifies one or two stages of the signal, and sends it to the single-chip microcomputer for signal comparison and processing. The single-chip microcomputer emits a sound when the predetermined threshold value is exceeded. Light alarm signal, drive LED light, horn or buzzer.
Features 1. Designed as an independent air chamber, which can reduce response time, improve measurement accuracy, buzzer does not interfere with sensor detection, air intake uses shutter, reduces the direct influence of dust and fumes on the sensor, sound and light alarm and Automatic signal output, easy to control external equipment 3, custom sensors: do cover film processing, equivalent to a very fine filter, can block the entry of granular material, high sensitivity, good selectivity, reduce the false positive rate.
4, sensor failure automatic detection 5, after the alarm, when the gas concentration is lower than the alarm set value, the detector automatically reset
Precautions for installation (1) The alarm probe is mainly a detection element that contacts the combustion gas sensor. The platinum wire coil is coated with alumina and a binder to form a sphere. The outer surface is accompanied by platinum, palladium and other rare metals. Therefore, be careful when installing to avoid damaging the probe.
(2) The installation height of the alarm should generally be 160-170cm, so that maintenance personnel can carry out routine maintenance.
(3) The alarm is a safety instrument, sound and light display function, and it should be installed in the place where the staff can easily see and hear, so as to eliminate the hidden trouble in time.
(4) There must be no strong electromagnetic fields (such as high-power motors and transformers) that affect the operation of the instrument around the alarm.
(5) The density of the gas to be measured is different, and the installation position of the indoor probe should also be different. When the measured gas density is less than the air density, the probe should be installed 30cm away from the roof and downward; otherwise, the probe should be installed 30cm away from the ground and upward.
