It may also be a pressure sensor which signals the deviation of the set pressure predetermined by the shield control device from the measured actual pressure in the form of a deviation signal. Signaling can be acoustic or optical. | 05-03-2012 |
20120170981 | HYDRAULIC CIRCUIT FOR LONGWALL SUPPORT - A hydraulic circuit for longwall support for use in underground mining for supporting a longwall by means of a plurality of support shields comprises in the annular piston line of each cylinder/piston unit a pressure sensor. Said pressure sensor upon reaching a predetermined maximum pressure activates a pressure deviation signal, which causes the entire longwall to be depressurized by means of a longwall shut-off valve. The pressure deviation signal is blocked for one of the hydraulic valves against each triggering signal. | 07-05-2012 |
