In the complex and ever-changing environment underground in coal mines, precise monitoring of fluid (water, gas, emulsion, etc.) flow is not only the key to optimizing production, but also the lifeline to ensure operational safety and prevent disasters! Today, let's get to know this "safety guard" who silently guards the underground fluid system - the intrinsically safe flow transmitter for mining.

1、 What is' intrinsic safety type '? Safety is the cornerstone of coal mines!

Intrinsic safety type ", also known as intrinsic safety type, is one of the most important explosion-proof types of electrical equipment in coal mines. The core concept is:

Energy limitation: The device's own circuit is designed to strictly limit electrical energy to extremely low levels (even in fault states such as short circuits and open circuits).

Eliminate sparks: Even in hazardous gas environments such as gas and coal dust, the electrical sparks or thermal energy generated inside the equipment are not sufficient to ignite explosive mixtures.

Double protection: usually needs to be used in conjunction with associated safety barriers to further ensure absolute energy safety when entering hazardous areas.

The intrinsically safe flow transmitter for mining is designed and manufactured based on this highest safety standard, and is used for flow monitoring in flammable and explosive environments underground in coal minesAn'sSelect all options.

2、 Core Value: Why is it necessary?

Safety and explosion prevention, life first:

holdNational Authority MachineThe mining product safety mark certificate (MA mark) issued by the organization is the "pass" to enter the coal mine underground.

Meet the explosion-proof level requirements of mining intrinsic safety types such as Ex ia I Ma or Ex ib I Ma.

Fundamentally eliminate the risk of electric spark explosions caused by flow monitoring equipment, providing solid guarantees for the safety of miners' lives and mine facilities.

Accurate measurement, optimized production:

Adopting advanced sensing technology to achieve high-precision and high stability measurement of fluid flow rate.

Real time monitoring of key parameters such as water supply and drainage, ventilation system air volume, and hydraulic support emulsion flow rate, providing reliable data support for production scheduling, energy management, and equipment protection.

Durable and adaptable to harsh environments:

The protection level of the shell usually reaches IP65/IP67 or even higher, dustproof and waterproof, and resistant to underground moisture, water spray, and dust pollution.

The key components are made of corrosion-resistant and impact resistant materials to ensure long-term stable operation in underground environments with vibration, impact, high humidity, and high dust.

Stable and reliable, worry free maintenance:

The intrinsic safety design itself reduces the number of failure points and improves the overall reliability of the system.

Modular design facilitates installation, debugging, and maintenance.

Low power design, suitable for underground power supply conditions.

Intelligent interconnection, helping smart mines:

Output standard signals (4-20mA, RS485 Modbus, etc.), seamlessly integrated into mine automation control systems (DCS/SCADA) or integrated monitoring platforms.

The remote monitoring, real-time alarm, historical recording and analysis of traffic data are important perception units for building smart and transparent mines.

3、 Typical application scenarios

The intrinsically safe flow transmitter for mining is widely used in underground coal mines and is the key "ear and eye" to ensure the safe and efficient operation of various systems

Mine water supply and drainage system: Monitor the flow of water in the main drainage pump room, mining area water pump room, and working face to prevent water disasters.

Fire prevention and extinguishing system: monitor the liquid/gas flow of grouting, nitrogen injection, spray dust suppression and other systems to ensure the effective implementation of fire prevention and extinguishing measures.

Comprehensive mining face: Monitor the supply flow rate of hydraulic support emulsion pump station to ensure the support performance of the support.

Pressure air self rescue system: Monitor the flow rate of the pressure air pipeline to ensure sufficient gas supply in emergency situations.

4、 Key points for selection: Safety and compliance are prerequisites

When choosing intrinsically safe flow transmitters for mining, it is important to remember:

MA certification is a red line: without a valid mining product safety mark certificate, it is strictly prohibited to go underground!

Match explosion-proof level: Confirm that the explosion-proof mark of the equipment (such as Ex ia I Ma) meets the requirements of the place of use.

Selection is key: choose the appropriate measurement principle and model based on the measured medium (water, gas, emulsion, etc.), flow range, pipeline size, pressure and temperature, accuracy requirements, output signal, etc.

Regular channel procurement: Choose suppliers with good reputation, comprehensive after-sales service, and technical support.

5、 Conclusion: Safe investment, infinite value

The intrinsically safe flow transmitter for mining is not only a measuring instrument, but also an important safety barrier and efficiency engine in the coal mine safety production system. Its value far exceeds its own price:

Ensuring life safety: preventing major accidents caused by equipment failure and explosion.

Avoiding production downtime losses: Accurate monitoring ensures stable system operation and reduces unplanned downtime.

Optimize resource allocation: Accurate measurement provides a basis for energy conservation, consumption reduction, and cost control.

Improving management level: data-driven decision-making to assist in the intelligent upgrading of mines.
