Intelligent Ammonia NH3 Gas Sensor

The Bestian Intelligent Ammonia NH3 Gas Sensor is an intelligent sensor launched primarily 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 types of toxic and harmful gases. Moreover, the production and replacement processes are simple, requiring no re-molding, which significantly reduces 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 operation, making it suitable for different requirements of industrial field or laboratory measurement. The sensor features simultaneous voltage and serial output, facilitating customer debugging and usage.

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 been calibrated and tested before leaving the factory; customers can directly collect and use the signal. Meanwhile, it features a small package volume, supports many types of gas detection, and has a unified structure, facilitating customer needs for direct use or secondary development.

The Intelligent Ammonia NH3 Gas Sensor is a product launched to adapt to current gas detection needs. The sensor processes the output signals of sensors with various detection principles through professional high-precision amplification circuits, noise-free processing, 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 cumbersome gas detection principles, detection types, or calibration difficulties; they can directly use the gas sensor and read accurate gas concentration information.

Sensor Installation:

The Intelligent Ammonia NH3 Gas Sensor is designed to be installed on a sensor socket using a plug-in method. To ensure reliable connection, dedicated sockets should be selected. The socket should be arranged according to the pin correspondence and installed vertically with firm soldering. According to special user requirements, the pin plug-in method may not be used, and an external lead wire method may be adopted instead; the wire length generally should not exceed 150mm. In non-explosion-proof areas, hot-swapping is allowed. In work sites with explosion-proof requirements, the power supply to 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, and underground parking lots. In recent years, it has been mainly used in fields such as environmental data collection, gas monitoring, the Internet of Things (IoT), drones, industrial robots, gridded atmospheric environmental monitors, and micro air quality monitoring stations. Its monitoring effectiveness has been widely recognized by users.
