The company's laser methane concentration detector is an explosion-proof methane concentration detector developed and produced in accordance with industrial design standards.
The instrument adopts the principle of spectral absorption. When the laser light emitted by the light source passes through the methane gas in the sensor probe, the light is absorbed in the sensor probe, and the light intensity changes. The methane concentration can be detected by detecting the change of light intensity. At the same time, the instrument has unique selectivity for methane, is not interfered by other gases, water vapor and dust, has no sensor poisoning, and does not need calibration, which greatly reduces the maintenance cost of customers.
The detector can be directly installed in zone 1 and zone 2 of the hazardous area; It has excellent performance, high stability and convenient installation and maintenance. It is widely used in indoor chemical workshop (chemical factory, pharmaceutical factory), chemical and pharmaceutical warehouse, cable and cosmetic factory, food factory, distillery, laboratory, coal mine, substation and other places. Its characteristics and advantages are as follows:
● ultra high measurement range: 0-100% vol range;
● selectivity: it has unique selectivity for methane and is not interfered by other gases, water vapor and dust;
● no poisoning: using the optical detection principle, the sensor will not be poisoned;
● the data is stable for a long time without calibration;
● design life: 5 years;
● fast response speed and high measurement accuracy;
● strong shockproof, waterproof and dustproof performance;
● aluminum alloy explosion-proof shell, strong and durable;
● support 24-hour continuous online monitoring;
● DC 12 ~ 30V wide voltage power supply;
● RS485 / 4-20mA / Hart multiple communication modes are optional;
● it is equipped with multiple cable outlets to facilitate on-site wiring construction;
