Absolute robustness for maximum reliability
Deep underground there are high temperatures, extreme vibrations and shocks. Durable and resistant technology is a must when it comes to withstanding these conditions. Our robust, wear-free and high-precision position measurement systems are particularly well suited for work under extreme conditions. With 25 years of relevant experience in position measurement in mining and maximum precision, Balluff's systems provide workers with maximum security.
Shields with hydraulic cylinders are used to protect miners in tunnels from falling rocks. BTL magnetostrictive linear position sensors of the K series integrated into the hydraulic cylinders allow exact positioning and secure monitoring of the shields.
When blast holes are drilled under ground, our BTL profile magnetostrictive linear position sensors installed outside of the cylinders monitor the drilling depth. The highly robust position measurement systems also operate reliably under extreme conditions. And ensure the necessary safety in tunnels as well as efficient mining of raw materials.
When searching for new raw material supplies, mobile drillers take soil samples to confirm potential deposits. Our BTL PF magnetostrictive linear position sensors are distinguished by their flat design and reliably ensure the correct drilling depth. So that you always know where the driller is.
In tunnel construction, boring machines remove rock centimeter by centimeter. Pushing cylinders, which continuously force the drill head into the rock, provide the strength needed for this. Our vibration-resistant BTL magnetostrictive linear position sensors correctly report the piston position with precision ( even under extreme conditions) and permit a smooth drilling process.
