Advantages of Mining Sensors
Intrinsically safe design, suitable for high-risk scenarios
Operates entirely within intrinsic safety circuit parameters, posing no risk of igniting gas. It can be directly installed on equipment located in high-gas areas, such as belt conveyors and winches, serving as a core component for underground equipment speed protection.
Multiple detection types, wide compatibility
Supports two detection methods: Hall effect (detects magnetic steel) and photoelectric effect (detects reflective markers). The hall type is suitable for dusty, dimly lit belt roadways with strong anti-interference capability. The photoelectric type is suitable for cleaner winch motors with higher detection accuracy.
Rapid response, timely warning
Response time ≤100 ms, enabling quick detection of sudden speed changes (e.G., sudden belt slippage, unexpected winch acceleration). This is 5 times faster than traditional mechanical speed switches, providing valuable shutdown time for equipment protection systems and preventing incident escalation.
Easy installation and maintenance, low cost
Compact and lightweight, installation time ≤20 minutes. Routine maintenance only requires quarterly cleaning of the detection end (removing dust) and checking the installation gap.

Origin |
China |
The mine speed sensor is an intrinsically safe detection device used in underground coal mines for real-time monitoring of the speed of rotating or linear motion equipment. Its core components include an intrinsically safe enclosure, a hall effect detection module (or photoelectric detection module), a signal processing circuit, and a 12v dc intrinsically safe power interface.
It is widely compatible with key underground equipment such as belt conveyors, scraper conveyors, winches, and motors. Its working principle involves detecting magnetic steel or reflective markers on rotating components of the equipment (e.G., belt conveyor rollers), converting mechanical speed into electrical signals, which are then processed to output switching or frequency signals.
Application of Mining Sensors
Collision avoidance
Ultrasonic sensors prevent machine collisions with material stacks or other equipment.
Vehicle automation
Ir and depth sensors aid autonomous vehicle navigation and operation.
Hydraulic systems
Pressure sensors monitor hydraulic/pneumatic systems for potential failures.
Gas monitoring
Pellistors and other sensors detect toxic/flammable gases (co, methane) and low oxygen levels.
Dust monitoring
Handheld and fixed sensors measure particulate matter (pm) to protect worker respiratory health.
Health monitoring
Vibration sensors (accelerometers) on conveyors, drills detect early wear.
Components of Mining Sensors
Sensing element: The part that interacts with the environment (e.G., a thermistor for heat, a crystal for pressure).
Gas sensors (e.G., methane, co2): Light source, sample chamber, optical filters, detector, sensing material.
Vibration/motion sensors (accelerometers): Piezoelectric elements or mems to detect movement/shaking.
Position/navigation sensors: Gps/glonass receivers, rfid readers, inertial measurement units (imus).
Transducer: Converts the physical change detected by the element into an electrical signal (e.G., voltage, resistance).
Microprocessor unit (mpu): Manages sensor functions, conditions signals, performs self-diagnosis, and runs algorithms.
Pressure sensors: Piezoresistive or piezoelectric diaphragms.
Temperature sensors: Thermistors, thermocouples, rtds.
Environmental sensors: Humidity (capacitive), sound, light sensors.
Memory: Stores data, settings, and calibration information.
Communication module/transceiver: Transmits data wirelessly (wi-fi, lora) or via cable.
Power source: Battery or energy harvesting unit.
