Product Overview
The Intrinsically Safe Mining Level Sensor is a liquid-level monitoring device for complex underground coal-mine environments, used for accurate measurement of key locations. It adopts a submersible measurement method for direct placement into pump-room sumps and similar liquid-storage areas, with a maximum range of 0–10 m and standard 4–20 mA output.
Product Description
Underground pump rooms depend on accurate water-level measurement: pumps must start before sumps overflow and stop when levels fall, and the sensors providing these readings must be safe in a gassy environment. The Intrinsically Safe Mining Level Sensor is a liquid-level monitoring device designed for complex underground coal-mine environments, used for accurate measurement at key locations such as sumps and water-storage areas.
The sensor adopts a submersible measurement method and can be placed directly into underground pump-room sumps and similar liquid-storage areas. Its maximum range reaches 0–10 m, covering the depth of most underground sump monitoring requirements. The measured level is output as a standard 4–20 mA current signal, giving reliable transmission to pump control and monitoring systems over long cable runs without signal degradation.
The intrinsically safe design permits installation inside hazardous underground areas, directly where the measurement is needed. By providing an accurate, submersible and intrinsically safe level measurement, the sensor supports automatic pump control, overflow prevention and water management in the most demanding underground installations.
