Product Introduction

Methane detection alarm chemical tank farm leakage safety monitoring - Product overview
Methane detection alarm is a gas detection device used for chemical tank farm leakage safety monitoring. Search keywords: methane detection alarm, chemical tank farm leakage safety monitoring, methane alarm. The alarm can continuously detect methane concentration in the tank farm. When the concentration exceeds the set value, it emits sound and light alarms and links ventilation and shut-off equipment. In chemical tank farm leakage safety monitoring, the methane detection alarm can reflect methane changes in tank breathing valves, pipelines, and pump areas in real time, preventing leakage and explosion accidents.

Methane detection alarm chemical tank farm leakage safety monitoring - Working principle
The methane detection alarm uses a catalytic combustion sensor or infrared sensor to output an electrical signal by detecting methane concentration, and after circuit processing determines whether to alarm. In chemical tank farm leakage safety monitoring, the methane detection alarm supports 4-20mA, RS485, and Modbus outputs and can be connected to PLC, DCS, and gas alarm control systems. The alarm has an explosion-proof housing and a high protection rating, making it suitable for outdoor and explosion-proof environments in chemical tank farms.

Methane detection alarm chemical tank farm leakage safety monitoring - Application scenarios
Methane detection alarms are widely used in storage tanks, pump rooms, loading and unloading platforms, and pipeline areas of chemical tank farms. In chemical tank farm leakage safety monitoring, methane detection alarms can be installed near breathing valves, at pump outlets, and along personnel inspection routes. The alarm can be linked with exhaust fans, shut-off valves, and fire protection systems to achieve automatic handling. For large chemical tank farms, methane detection alarms can form a multi-point monitoring network and upload data uniformly to the control room.

Methane detection alarm chemical tank farm leakage safety monitoring - Technical advantages
The methane detection alarm has advantages such as fast response, good stability, and convenient linkage. In chemical tank farm leakage safety monitoring, the methane detection alarm uses industrial-grade sensors and explosion-proof design, making it suitable for long-term operation. The alarm supports sound and light alarms, remote output, and fault self-check, and is easy to maintain. When selecting a methane detection alarm, attention should be paid to detection range, accuracy, response time, explosion-proof rating, and output signal to ensure it meets the needs of chemical tank farm leakage safety monitoring.
