NBM-19B Near Bit Continuous INC Module
The NBM-19B is an Ultra-small (0.75” x 6.0” Nom.) Dynamic Inclination Module delivering ‘next-level’ Continuous INC accuracy. The sensor employs 3-axes of highly ruggedised MEMS devices and 24-Bit data acquisition to delivery industry leading Continuous INC precision. Azimuth’s proprietary dynamic algorithm has been honed for high shock (up to 50G rms) and high torque applications at any angle from vertical to horizontal.
The module provides fully computed outputs or raw axes if required. Communications mode and data frequency is fully user configurable and the unit is fully supported with an accompanying PC Software application. The NBM-19B module is qualified and tested under the same rigorous conditions expected of all Azimuth sensors.
