The intrinsically safe smoke sensor is suitable for coal mine environments that contain explosive gas mixtures such as methane and coal dust. It is used in conjunction with the host of the comprehensive protection device for coal mine belt conveyors or the host of the mine-use automatic water-spraying dust reduction device. Integrated into an intrinsically safe system signal device, the sensor detects smoke produced by the belt conveyor due to frictional heating or other causes. When the smoke concentration reaches a predefined level, the smoke sensor outputs a signal to the host.
Technical Parameters
- The sensor should actuate when the smoke concentration reaches 5% obs/m, and the response time should not be more than 20 seconds.
- Working voltage: DC12~24V; working current should not be more than 200mA.
- Switch quantity signal output: In the absence of smoke, the contact is open; in the presence of smoke, the contact closes.
Advantages
The Intrinsically Safe Smoke Sensor is designed with safety and stability in mind, typically constructed from materials that resist high temperatures and corrosion to withstand harsh environments.
It features waterproof and dust-proof properties, ensuring normal operation under diverse conditions.
Equipped with automatic calibration and self-test functions, the sensor consistently maintains an efficient working state.
Integration with monitoring systems allows for remote monitoring and alarms, enhancing the efficiency of fire emergency responses.
Installation Precautions
1. When installing the Intrinsically Safe Smoke Sensor, follow the instructions in the product manual strictly.
2. Choose an appropriate installation location to ensure effective smoke detection.
3. Consider the installation height, angle, and other parameters critically to optimize detection performance.
4. During installation, ensure the wiring is correct and secure to prevent issues such as poor contact.
5. Ensure proper grounding of the sensor to guarantee safety and reliability.
