SlideMinder extensometers can be customized to transmit data using 900MHz spread spectrum radio modems configured to comply with regional communication regulations and/or the local Wi-Fi network.
The FOGLight (Fall of Ground) indicator is an early warning device designed to detect and warn mining crews of separation in the rock above, helping to prevent losses and providing a safer work environment underground. The FOGLight is simple to install, manufactured of tough material, is intrinsically safe and has a highly visible flashing LED indicator to highlight potentially unsafe movement in the hanging wall. The DUAL FOGLight includes the LED functionality of the standard version but includes a second and independent mechanically activated trigger.
Radio Repeaters & Remote Warning Strobes
900MHz Repeater units are available in Standard and International frequency ranges to accommodate extended distances or line-of-site obstructions. (Not needed with all systems.) Remote Warning Strobe units are available for increased warning visibility.
The FOGStick is an early warning device designed to detect and warn mining crews of closure of the roof above a working area. Upon installation the device is spring loaded between the roof and the floor to monitor closure in an excavation.
