Nautitech Mining Systems will be unveiling a new high-precision underground gas sensor among a range of specialist electronics products on Stand 2511 at AIMEX – Asia-Pacific’s International Mining Exhibition, to be held at the Sydney Showground, Sydney Olympic Park from August 20-23, 2013. According to Nautitech representative Nick Smith, it’s Ex ia (Ex ia)rated sensor has been purpose-built for coal mines and is currently undergoing the final stages of its formal certification process.
“Compared to its predecessor, it has significantly improved  ingress protection, a higher rate of precision and faster warm-up and response times,” said Smith.
“It will be available for use with new shutdown systems or as a retrofit kit for existing systems.”

A new product from Nautitech at AIMEX will be its new Spitfire power-line modem, which takes data from underground machines, such as shearers and continuous miners, and transfers it to the surface via the trailing cable – allowing improved system control and productivity analysis. “Underground testing on multiple longwall shearers in Australia has shown a link capacity that ranges from 110 Mbps for a 450 m trailing cable, up to 160 Mbps for 280 m,” said Smith. “During six months of testing, there were no communications outages; we believe this is a breakthrough in power line modem performance for mining.” Also featured will be the company’s Extreme cam – Ex d-rated infrared camera kit, which is designed to give operators of machines, such as LHDs and shuttle cars, more warning of nearby personnel. “Contrast settings can be adjusted so that, when a person is nearby, their body heat shows brightly against a dark background, immediately catching the operator's attention,” said Smith. “Nautitech has a history of creating industry firsts for products in the underground coal sector and are known for the ongoing dependability of those products,” he said.
