The HX-ATTI-01 Attitude Measurement Instrument (hereinafter referred to as the Attitude Meter) is primarily used to determine the azimuth and inclination angles of the derrick frame. It provides an azimuth reference through north-seeking, followed by attitude measurement at specified positions, thereby obtaining the azimuth and inclination angles at those locations.
Environmental conditions for use
- Environmental temperature: (0~+40) ℃
- Average relative humidity: ≤ 95% (+25 ℃)
- Atmospheric pressure: (80-106) kPa
- Used in coal mines with methane mixtures and coal dust explosion hazards, but without corrosive gases that damage insulation
- Storage temperature: (-20~+60) ℃
Working principle and structural characteristics
The HX-ATTI-01 attitude sensor is an intrinsically safe type for mining and is an instrument based on gyroscope technology. Using a gyroscope to search north and provide directional reference; After obtaining the azimuth reference, the three-axis accelerometer, MEMS gyroscope, and signal calculation circuit are used to complete the attitude measurement at the specified position. The measurement process is as follows: place the machine horizontally stationary next to the drilling equipment to be measured, search for north, and after the north search is completed, take the machine to the drilling equipment for measurement, and obtain the azimuth and inclination of the drilling equipment, which will be displayed on the LCD.
Main specifications
Working voltage: DC 7.4 V, working voltage range: (6.4-8.4) V.DC;
The measurement range and basic error of inclination and azimuth are shown in the following table:
| Items | Measurement range | Resolution | Error |
| Inclination | -90°～90° | 0.05° | ±0.1° |
| Azimuth | 0°～360° | 0.1° | ±0.5° |
Applications
- The HX-ATTI-01 attitude measuring instrument is mainly for adjusting and measuring the drilling angle of the drilling rig, improving the accuracy of the drilling direction of the drilling rig.
