Product Introduction
Oxygen leakage alarm sensor module - Product overview
The oxygen leakage alarm sensor module is a gas detection module used for hypoxia monitoring in sewage treatment biogas areas. Search keywords: oxygen leakage alarm sensor module, hypoxia monitoring in sewage treatment biogas areas, oxygen alarm. This module can continuously detect the oxygen concentration in biogas areas and output standard signals or switching values. In hypoxia monitoring in sewage treatment biogas areas, the oxygen leakage alarm sensor module can reflect in real time the oxygen changes in digestion tanks, biogas holders, and pipeline areas, preventing personnel from hypoxia and suffocation and the risk of biogas explosions.
Oxygen leakage alarm sensor module - Working principle
The oxygen leakage alarm sensor module uses an electrochemical sensor to output an electrical signal by detecting oxygen concentration, which is converted into RS485, 4-20mA, or switching value output after circuit processing. In hypoxia monitoring in sewage treatment biogas areas, the oxygen leakage alarm sensor module supports the Modbus protocol and remote calibration and can be connected to PLCs, DCSs, and gas alarm controllers. The module has an explosion-proof housing and a high protection rating, making it suitable for humid, corrosive, and explosion-proof environments in biogas areas.
Oxygen leakage alarm sensor module - Application scenarios
The oxygen leakage alarm sensor module is widely used in digestion tanks, biogas holders, biogas generator rooms, and pipeline areas of sewage treatment plants. In hypoxia monitoring in sewage treatment biogas areas, the oxygen leakage alarm sensor module can be installed near digestion tanks, biogas holders, and personnel inspection passages. The module can be linked with exhaust fans, shut-off valves, and fire protection systems to achieve automatic handling. For large sewage treatment plants, the oxygen leakage alarm sensor module can form a multi-point monitoring network and upload data uniformly to the control room.
Oxygen leakage alarm sensor module - Technical advantages
The oxygen leakage alarm sensor module has advantages such as small size, easy integration, and flexible output. In hypoxia monitoring in sewage treatment biogas areas, the oxygen leakage alarm sensor module uses industrial-grade sensors and an explosion-proof design, making it suitable for long-term operation. The module supports audible and visual alarms, remote output, and fault self-diagnosis, and is easy to maintain. When selecting an oxygen leakage alarm sensor module, attention should be paid to the detection range, accuracy, response time, explosion-proof rating, and output method to ensure reliable and effective hypoxia monitoring in sewage treatment biogas areas.
