Robust position sensors for drilling equipment
One of the world’s largest providers of products and services to the oil and gas industries is replacing potentiometers with MacroSensors’ LVDT linear position sensors as a critical position feedback component on its down-hole drilling equipment.
Installed on a rotary steerable drilling system as part of the steering mechanism, the sensors provide feedback on radial positions of the drill bit for proper geosteering and optimum wellbore placement for faster, more accurate and safer drilling operations. Bestech Australia offers a full range of MacroSensor LVDTs to meet any specific applications.
High vibrations caused by the drill’s impact and medium to hard surfaces caused potentiometers failed prematurely to provide accurate position feedback. This leads to a frustrated situation that pots had to be replaced each time the drill was serviced, which was typically around 200 hours.
MacroSensors offer a longer life solution that provides reliable position feedback under the hostile conditions and high vibrations inherent to down-hole drilling. Using modern materials and construction techniques, these sensors withstand high vibrations up to 20g, temperatures up to 400 degrees and high pressures up to 2413 bar.
Interfacing with a conventional differential input LVDT signal conditioner, the sensors provide position feedback to operators at the surface, where drilling performance data can be continuously monitored at both the rig site and remote locations.
