Fiber optic gyroscope VG 071PT - is modified VG 071P with embedded TMP36 - sensor of internal temperature. It is designed to operate at low temperatures. Modern materials and recent technology achievements are used for its fabrication. Plastic housing gives to the model much lower weight. Differential output is well adapted to match ADC input.

RECOMMENDATIONS AND PRECAUTIONS
|
1. |
Do not deform housing and output pins |
|
2. |
Fragile components inside - no shocks, no drop |
|
3. |
Treat as electrostatic sensitive unit |
|
4. |
Is designed to be mounted inside water protected equipment |
|
5. |
Increased humidity shortens essentially lifetime |
|
6. |
Power must be off during connecting |
|
7. |
Soldering to contacts - by low-temperature solder |
