1.Exchange our DTG-E2 in customer's continuous north seeking gyro tools



Using gyroscope for customer’s geological tools, application condition as following: probes are built for borehole diameter of 

55mm, operating probes up to deep of 500m, supplying power is 35V DC and current of 100 mA as standard. 


a.The performance of gyroscope what the customers focus on, such as:
                      Outside diameter: 29mm,   
                      Temperature range: -10~100 degree centigrade.
                      Maximum Operating power is: 4W
                      Power supply of the Gyroscope: 12V, 400Hz;   ±15V, DC;  ±5V, 16KHz
                      Electronic board : 200*30(L*W) 
                      Power supply of the Electronic board: ±15V, DC. Current: 800mA. 

Customers need to prepare two power supply of ±12V~±15V, DC when using our electronic board.



b. About DTG-E2 PCB part, information as following:
The output of DTG-E2 gyroscope is the analog voltage output, directly proportional to angular velocity,collect the voltage value, 

and with the voltage value divided by the scale factor, then we can get the angular velocity value. Customers 

need to do some computation to get the Azimuth data and the compass data.the scale factor, then we can get 

the angular velocity value. Customers need to do some computation to get the Azimuth data and the compass data.


2. The pictures of Quartz accelerometer temperature test:

 

 

Test was continued 28 hours in thermo chamber. Temperature changes are shown in lower graphic. It has an overall Scale Factor (SF) repeatability about 500-600 ppm. Error of SF are repeated when another ER-I/A-02 Quartz accelerometer is tested. From the pictures of temperature accelerometer test, Scale Factor did twice within the range of temperature, it is the equivalent of a full scale degree factor of repeatability.
