RDS-M Mine Radar Sensor, Special Explosion-Proof

The RDS-M mine radar sensor, special explosion-proof, is designed for continuous non-contact measurement of the level of bulk and liquid media in bunkers, ore passes, and water sumps, for measuring distances to various surfaces and objects, for measuring the height and profile of stockpiles, and for detecting the presence of objects in a specified zone. The radar sensor is suitable for use in underground workings of mines, ore mines, and their surface structures, including those hazardous due to gas and/or dust, in accordance with the assigned explosion protection marking and the requirements of industry safety regulations.

Advantages:

mine special explosion-proof design ensuring safe operation in underground workings of mines and ore mines hazardous due to gas and dust with constant presence of an explosive atmosphere
user-friendly interface
flexible configuration allowing the equipment to be used in various project solutions
quick installation
