high work temperature quartz crystal accelerometer for oil drilling
The Accelerometeroutput current and the force received are linear output, and the user can select the appropriate sampling resistor to achieve the highest accuracy output. At the same time, the Tempe Sensor is built in, and the output current changes linearly with temperature. The user compensates the Deviation value and Scale factor to reduce the temperature effect (optional). The product can be used for both static and dynamic testing and is a standard vibration sensor
