Single NH3 gas sensor

Intelligent Ammonia NH3 Gas Sensor

The Besian Intelligent Ammonia NH3 Gas Sensor is an intelligent sensor mainly launched for gas equipment manufacturing enterprises, including industrial process gas control equipment, environmental monitoring gas equipment, gas analysis instrument equipment, etc.; it is developed and produced mainly to solve problems such as the wide variety of gas detection types, incompatibility of gas sensors, complex production calibration, and limited development and replacement.

By adopting the intelligent Hydrogen Sulfide H2S sensor module developed by our company, you only need to develop one product to meet the monitoring needs of more than two hundred kinds of toxic and harmful gases, and the production and replacement processes are simple, without the need for re-molding, greatly reducing the enterprise's R&D costs, production costs, and after-sales costs.

At the same time, this sensor is easy to operate, accurate in measurement, and reliable in work, suitable for different requirements of industrial field or laboratory measurement. The sensor features simultaneous voltage and serial output, facilitating customer debugging and use.

The Intelligent Ammonia NH3 Gas Sensor is based on high-precision gas-sensitive elements, converting the weak output signal of the sensor into standard signals that are easier for customers to apply, such as 0~5V, 4~20mA, TTL, RS485, etc. The intelligent gas sensor has completed calibration and testing before leaving the factory, and customers can directly collect signals for use; at the same time, the package volume is small, the types of detected gases are many, and the structure is unified, facilitating customer direct use or secondary development needs.

The Intelligent Ammonia NH3 Gas Sensor is a product launched to meet current gas detection needs. The sensor processes the output signals of sensors with various different detection principles through professional high-precision amplification circuits without noise, temperature compensation, high-purity gas calibration, and other steps, converting gas concentration signals into standard digital and analog signals. Users do not need to deal with complex and tedious gas detection principles, detection types, calibration difficulties, and other problems, and can directly use the gas sensor to read accurate gas concentration information.

Sensor Installation:

The Intelligent Ammonia NH3 Gas Sensor is designed to be installed on the sensor socket in a plug-in manner. To ensure reliable connection, dedicated sockets should be selected. The sockets should be arranged according to the pin correspondence method and installed vertically with firm soldering. According to user's special requirements, the pin plug-in method may not be used, but an external lead wire method may be adopted instead; the wire length generally does not exceed 150mm. In non-explosion-proof places, hot-swapping with power on is allowed. In work sites with explosion-proof requirements, the power supply of the equipment connected to the sensor must be turned off before installation.

Application Market

The Intelligent Ammonia NH3 Gas Sensor is inseparable from fields such as petroleum, petrochemicals, metallurgy, chemical industry, electric power, telecommunications, gas, mining, pharmaceuticals, municipal sewage treatment, indoor environment, atmospheric environmental protection, transportation equipment, transportation, tunnel safety, underground parking lots, etc. In recent years, it is mainly used in fields such as environmental data collection, gas monitoring, Internet of Things, drones, industrial robots, gridded atmospheric environmental monitors, and micro air quality monitoring stations. Its monitoring effect has been widely recognized by users.
