Introduction: JSA5-Ex LPG detector is suitable for continuous online detection of LPG concentration in various industrial environments and leaks and on-site sound and light alarms. The controller technology has the advantages of stable signal, high precision and good repeatability. The explosion-proof wiring method is suitable for various dangerous places. The instrument is compatible with various control alarms, PLC, DCS and other control systems, and can realize on-site alarm and remote monitoring and alarm functions at the same time. Features: 1. The explosion-proof grade is ExdⅡCT6 2. Imported combustible gas sensor with high precision and long life 3. Automatic temperature, humidity compensation, zero point, full scale drift compensation 4. Automatic protection function against high concentration gas shock 5. Three-wire 4～20mA output 6. Two cable inlets for easy on-site installation 7. Independent air chamber structure, fast response, excellent long-term stability. Technical indicators: Detection gas: liquefied petroleum, natural gas and other gases in the air
