The GUL79D intrinsically safe mining radar level imaging scanner uses electromagnetic waves for multi-point scanning and 3D imaging. It is a proven industrial method for measuring solid material and volume, largely independent of material type, physical properties, storage layout, and silo size, and it is built for harsh storage environments. The acoustic signal includes a self-cleaning function that limits material buildup on the inner surface, so the instrument keeps working reliably with very little maintenance. Platform software installed on a networked industrial PC collects data over RS485 or Ethernet, updates a live 3D material image, and reports level, ullage, material height, volume and trends. It can output an average level, or a 4–20 mA level signal to the customer’s requirement.

The intrinsically safe mining pressure sensor uses a diffused-silicon element and a fully digital circuit. It transmits signals over long distances, uses an all-stainless-steel body, and is easy to install. Interference and shock resistance are high. It suits coal mining, environmental protection and medical applications.

The intelligent main coal-flow AI video recognition system (KBA12(W) intrinsically safe mining image-processing camera) follows the coal-mine intelligent construction guidelines issued by the National Mine Safety Administration. Digital image processing reads the video, extracts key information, regulates coal flow across the mine and identifies belt hazards, helping mines run with fewer people, greater safety and higher efficiency.

The GUL69 intrinsically safe mining radar level sensor is a high-frequency microwave pulse instrument. A horn antenna focuses the beam so it reflects from the material surface. The antenna transmits a narrow microwave pulse downward; the echo returns to the antenna and the electronics convert it into a level signal. Because the wave travels at the speed of light, the measurement is effectively instantaneous. It is used for level measurement and control in underground and surface coal bunkers and in silos holding liquids or solids.

The GLC150/320 flameproof and intrinsically safe mining ultrasonic flowmeter is designed for long-term online measurement of liquid flow in pipes. It is widely used in water supply, heating, water conservancy, metallurgy, chemicals, machinery and energy, for production monitoring, water-balance commissioning, heat-network balancing and energy-saving checks. Measurable media include drinking water, river water, seawater, groundwater, cooling water, high-temperature water, wastewater, lubricating oil, diesel, fuel oil, chemical liquids and other homogeneous fluids.

The GWY120/10 intrinsically safe mining temperature and level sensor measures liquid level across coal, petrochemical, power, water and environmental systems. It converts changes in level and temperature into an electrical signal, or another required output, so equipment can monitor and control both. A compact structure, simple adjustment and flexible mounting make it straightforward to use.

The GLW15/6 intrinsically safe mining flow sensor monitors liquid flow in a pipe in real time and provides a current output. It can watch flow rate, detect loss of flow, or protect a pump from running dry. It is used for pipeline flow monitoring and to protect critical equipment when flow fails.

The GWP138 intrinsically safe mining temperature sensor uses a PT100 element. It is stable for long-distance signal transmission, built entirely in stainless steel, and easy to install. Interference and shock resistance are high. It measures temperature in coal, petrochemical, metallurgy, power and hydropower sites.

The intrinsically safe mining load cell uses a diffused-silicon element and a fully digital circuit. It transmits signals over long distances, uses an all-stainless-steel body, and is easy to install. Interference and shock resistance are high. It suits coal mining, environmental protection and medical applications.
