Product Introduction
Oxygen Gas Detection Transmitter - Product Overview
The oxygen gas detection transmitter is a fixed gas detection transmitter device used for metallurgical furnace oxygen deficiency and oxygen enrichment monitoring. Search keywords: oxygen gas detection transmitter, metallurgical furnace oxygen deficiency and oxygen enrichment monitoring, oxygen alarm. The transmitter can continuously detect oxygen concentration in the furnace area and convert the concentration signal into a standard signal output. In metallurgical furnace oxygen deficiency and oxygen enrichment monitoring, the oxygen gas detection transmitter can reflect furnace combustion and oxygen leakage risks in real time, helping operators adjust processes and ventilation promptly.
Oxygen Gas Detection Transmitter - Working Principle
Oxygen gas detection transmitters typically use electrochemical sensors or paramagnetic oxygen sensors to detect oxygen concentration and output electrical signals, which are converted into 4-20mA, RS485, or Modbus signals after circuit processing. In metallurgical furnace oxygen deficiency and oxygen enrichment monitoring, oxygen gas detection transmitters support remote calibration and fault self-diagnosis, and can be connected to PLC, DCS, and gas alarm control systems. The transmitter features an explosion-proof housing and a high protection rating, making it suitable for high-temperature and high-dust environments in metallurgical furnaces.
Oxygen Gas Detection Transmitter - Application Scenarios
Oxygen gas detection transmitters are widely used in heating furnaces, annealing furnaces, smelting furnaces, and heat treatment areas of metallurgical furnaces. In metallurgical furnace oxygen deficiency and oxygen enrichment monitoring, oxygen gas detection transmitters can be installed near burners, beside flues, and along personnel inspection routes. The transmitter can be linked with exhaust fans, shut-off valves, and fire protection systems to achieve automatic handling. For large metallurgical plants, oxygen gas detection transmitters can form a multi-point monitoring network and upload data uniformly to the control room.
Oxygen Gas Detection Transmitter - Technical Advantages
Oxygen gas detection transmitters have advantages such as fast response, good stability, and standard output. In metallurgical furnace oxygen deficiency and oxygen enrichment monitoring, oxygen gas detection transmitters use industrial-grade sensors and explosion-proof design, making them suitable for long-term operation. The transmitter supports remote calibration, fault self-diagnosis, and HART communication, making maintenance convenient. When selecting an oxygen gas detection transmitter, attention should be paid to detection range, accuracy, response time, explosion-proof rating, and output signal to ensure it meets the needs of metallurgical furnace oxygen deficiency and oxygen enrichment monitoring.
