1、 Introduction to industrial explosion-proof split type oxygen transmitter

The BYG500-O2 industrial explosion-proof split type oxygen transmitter continuously detects oxygen gas in the atmosphere online and provides sound and light alarms. It not only controls gas concentration in special occasions, but also has a warning effect on gas leaks in dangerous sites, timely protecting the safety of life and property on various sites. Instruments are widely used in industries such as petroleum, chemical, metallurgy, fire protection, coal mining, electricity, ships, environmental protection, telecommunications, and medical care. The BYG500-O2 detector adopts imported sensors combined with high-speed and high-precision processing circuits, which have the advantages of stable signals, high accuracy, and good repeatability. It also adopts explosion-proof design and is suitable for various hazardous situations. The instrument outputs various standard signals and is compatible with various alarm systems, PLC, DCS and other control systems.
