Purpose:
The instrument is a small instrument used to determine inclination of borehole. It is suitable to determine dip angle and azimuth angle in multi-point mode in non-magnetic borehole, which is more than 46 mm in diameter. The instrument determines dip angle and azimuth angle of borehole using lead hammer principle and magnet needle direction principle. The reading of azimuth angle and dip angle can be obtained from controlling case. The instrument is simple, and convenient to be operated. It is with the same accuracy with that of large bore instrument.
Technical parameters:
1. Azimuth angle:
(1) Measurement range: 4°～356°;
(2) Measurement error: ±4° (When the dip angle is 3°～ 50°);
2. Dip angle:
(1) Measurement range: 0～50°;
(2) Measurement error: ≤±30′;
3. Power supply: DC 12V (when not connect to cable);
4. Airproof performance: it can endure pressure of not less than 15 MPa;
5. Maximum working temperature for inclinometer probe: 50 ℃;
6. Maximum accelerating speed for inclinometer probe;
7. Instrument size:
(1) Controlling case: 300×210×85mm, 1.5 kg;
(2) Inclinometer probe: Φ40×1260 mm, 6 kg;
(3) Extending tube: Φ40×570 mm, 2 kg;
