WORKING PRINCIPLE

It adopts imported core control unit and uses the principle of capacitive miniature pendulum. According to the earth gravity principle, when the dip angle unit is inclined, the gravity of the earth can generate a gravity component on the corresponding pendulum, the corresponding capacitance can be changed, and the dip angle can be obtained by amplifying, filtering and converting the capacitance.

MAIN FEATURES

• Range (Roll angle ±180°, pitch angle ±90°, azimuth angle ±180°)
• Roll&Pitch Dynamic accuracy: ± 0.1°
• Static accuracy: ± 0.05°
• RS485/232/TTL output Optional
• DC 9~36V wide voltage input
• Wide temperature operation -40~+ 85℃
• IP67/IP68 Protection level Optional

INSTALLATION AXIAL

HDA446T uses the ENU coordinate system, a right-hand system. According to the rotation order of Z-X-Y, when the positive direction of the Y axis points to the front of the carrier, the angle rotated around the Z axis is the heading angle, the angle rotated around the X axis is the pitch angle, and the angle rotated around the Y axis is the roll angle.
