BS03 Multi Gas Detector For Industrial Comprehensive safety

Detailed Product Description

Fixed Gas Detector Description
BS03 is a fixed gas detector installed in a place where potential gas hazard exists to measure oxygen, toxic gas and combustible gas. It shows not only the concentration of gas but also diagnostic result of the unit itself through the LED screen and LED lights and can be connected to the control panel with a standard 4-20mA analog output.

It is applicable to explosion-proof places: Steelworks, Petrochemical plants, Shipyards, Watertreatment plants, Mines, Power plants, Food industry etc.

Fixed Gas Detector Key Feature

• Interchangeable smart sensor module
• Intrinsically safe
• Built-in sampling pump (optional)
• Visual, audible and vibration alarm
• Adjustable alarm levels and span calibration values
• Password management
• Self-test after power on
• Self-diagnostic and self-correction function
• Real-time clock

Catalytic Combustion Sensor Principle

1. Principle: The principle of using the heat released by the combustion reaction of combustible gas on its surface, that is, the temperature of the platinum wire coil increases due to combustion, and the resistance value of the coil increases. The concentration of the combustible gas can be known by measuring the change in the resistance value of the platinum wire, which is suitable for measuring low-concentration combustible gas.

2. Advantages: The performance is relatively stable. Most combustible gases can be measured by catalytic combustion sensors. The measurement is very linear and the cost is lower than that of electrochemical sensors.

3. Disadvantages: The process conditions are strict. Dust particles and droplets that affect the life and treatment efficiency of the catalyst are not allowed in the exhaust gas, and substances that poison the catalyst are not allowed to prevent catalyst poisoning.

4. Use: Mainly used to detect more combustible gases.
