NGT-075-B Gamma Tools

NGT-075-B

Gamma Tools (.075” OD)

Our NGT-075-B gamma tools are the smallest diameter scintillator gamma tools available on the market today. With an outside diameter of only 0.75” they are ideally suited for mounting within the drill-collar wall to make superior directional gamma sensors. We offer two versions of the NGT-075-B with various protection options for the tool and its electronics.

Magnetic materials are kept to an absolute minimum to limit interference with closely mounted magnetometers.

NGT-075-B
(w/ Molded Electronics Protection)
P/N 204-200-000

The latest version of the NGT-075-B contains our new Molded Electronics Protection optimized for extreme drilling environments. Pre-molded pads cover and protect the top and bottom of the circuit boards, replacing the traditional protective silicone mixture poured over the boards. This new encapsulation method of the circuit boards improves reliability by dispatching excessive heat and minimizes the impact of shock and vibration to the electronics. The molded pads also improve serviceability by allowing easy removal to provide access to the electronics for inspection and repair.

NGT-075-B
(w/ Encapsulation Sleeve)
P/N 204-400-000

CBG’s Encapsulation Sleeve is offered as an alternative to traditional collar mounting methods that may be less effective at protecting gamma tools in harsh drilling environments. Our molded encapsulation sleeve insulates the entire NGT-075-B tool, including its electronics. It reduces shock and vibration by 50% on the NGT-075-B when mounted in a collar. The pre-molded sleeve consists of two pieces that are approximately 1.0” OD when assembled around the .075” gamma tool. Ribbing on the outside of the sleeve provides gripping and allows for thermal expansion. The inside of the sleeve contains precisely molded impressions of the top and bottom of the circuit boards for electronics protection.
