Carbon dioxide detector has three output modes
The carbon dioxide detector adopts advanced single-chip microcomputer technology and non-dispersive infrared gas sensor (NDIR) technology. It has the characteristics of high measurement accuracy, long service life, fast response speed and convenient operation. It is suitable for detecting carbon dioxide gas concentration in various working environments.
The research and development of the carbon dioxide detector is in line with the current policy of the country to reform and rectify the deteriorating environmental problems. It can be said that the application of the carbon dioxide detector will have a large market in the next few years. The application of the carbon dioxide detector can not only prevent people from Health is threatened due to excessive carbon dioxide concentration, and at the same time, the high concentration of gas can be effectively used to control the output of the instrument, which can be said to kill two birds with one stone.
The carbon dioxide detector has three output modes:
1. Switch value/relay output: When the carbon dioxide concentration reaches the preset alarm value, the indicator light of the detector changes from green to red and flashes, and the relay is closed at the same time, and the corresponding ventilation equipment is turned on; when the carbon dioxide concentration is lower than the preset When the alarm value is reached, the indicator light turns green, the relay switch is disconnected, and the ventilation equipment is turned off.
2. 4-20mA current analog output: convert the collected carbon dioxide concentration signal into a 4-20mA current corresponding to the range and send it to PLC/DCS and other analog acquisition and control systems.
3. RS485 bus communication output: transmit the collected carbon dioxide concentration data to the control system, and can network multiple 485 devices and support Modbus communication protocol.
The carbon dioxide detector is an intrinsically safe device that continuously detects the concentration of carbon dioxide gas in the air. It adopts imported non-dispersive infrared sensors, which can accurately and quickly detect the concentration of carbon dioxide, effectively ensuring the safety of staff. The alarm function greatly meets the requirements of high reliability of equipment for industrial field safety monitoring. The professional and beautiful portable design is convenient for mobile use. This product is widely used in petroleum, chemical industry, metallurgy, refining, biopharmaceutical, household environmental protection, school laboratory and other fields.
As a gas detector in the new era, the carbon dioxide detector was born with its small and exquisite appearance, fast and accurate detection quality. In the next one to two years, the carbon dioxide detector will surely occupy the entire instrumentation industry and construction industry. Some People don't understand why carbon dioxide detectors have such a big market in the construction industry. The reason is that this kind of gas detector conforms to the needs of social development and environmental requirements. Air quality is getting more and more attention from the country. Then, carbon dioxide detectors will definitely have their place, and future buildings will definitely have the standard of gas detection. . For the healthy life of you and your family, welcome to buy a carbon dioxide detector.
