Project Description：China First Automobile Group Corporation referred to as "China FAW" or "FAW", large state-owned automobile manufacturer. Production environment in the air, the process with the cleanliness of pure gas and liquid and other air parameters (temperature / humidity, wind speed, pressure) of the plant has a crucial role. Using portable or vehicle-mounted air particle counter for clean room cleanliness regular manual inspection there is a disadvantage to this, in order to overcome the shortcomings of manual testing, using real-time monitoring system for environmental monitoring of clean rooms. Depending on the clean room requirements, different regions should clean design appropriate environmental monitoring system, both to meet the monitoring requirements and reducing sampling costs.

Introduction：Plant area dust sensors, smoke sensors, humidity sensors, nitrogen oxide sensor and a temperature sensor and other sensors collect information on the plant environment, the amount of current is converted to 4-20mA signal, through easy control of the amount of current fiber optic repeater YOA series 4- 20mA current amount information is converted to fiber-optic long-distance communications, uploaded to the control room, and then by the control center based on specific environmental data received to adjust treatment to improve the quality of the work environment.

Applications:YOA4-S-ST Industrial amount of current fiber optic repeater, 4 the amount of current, single-mode, ST connector. It supports two-wire, three-wire, four-wire sensors or transmitters
