Ns-DMA/B Electronic Inclinometer for Borehole Drilling ±0.1° Precision

Ns-DMA/B Electronic Inclinometer for Measuring the inclination angle, orientation of borehole drilling

Ns-DMA/B Electronic Inclinometer

Product Description
NS-DMA/B Electronic Inclinometer

1.1 Functions and Application

Measuring the inclination angle, orientation of magnetic operating face and orientation of high side operating face of at the end of the drilling hole or a specific position while drilling.

Widely applied for survey of well-hole drilling in the fields of petroleum, coal mine, irrigation establishment.

1.2 Features

Ø For various operational purposes:
Satisfying various survey purposes either for suspending measurement or self-floating measurement once equipped with different external protectors.
Ø High precision and reliability:
As the key part of inclinometer, acceleration sensor with a shockproof accelerometer have characteristics of high linearity,little temperature drifting and good recurrence, etc.
Ø Power-off protection:
Power failure caused by shakes or pressures would not result in operational disruption or data loss.
Ø Dynamic performance:
Excellent data collecting and processing in either dynamic or static performance.
Ø Shock and impact-resistance:
External multi-vibrate-resist buffer, both radial and axial.
Ø Low temperature environment suitable: Normal performance at -40ºC
Ø Deep-well measuring:
Equipped with heat insulation protector, normal working at 250ºC, under 125MPa
