AV4 series quartz flexible accelerometer is a high temperature and anti-vibration accelerometer, the product has excellent repeatability, starting performance, high temperature and high reliability characteristics, it can be used for static testing and dynamic testing, it is also a standard vibration sensor.
Products adopt unique high temperature design, packaging process and special circuit, product output current is proportional to the measured acceleration, the user can calculate the appropriate sampling resistance, achieve high precision output, and according to the user demand built-in temperature sensor, used for the partial value and scale factor compensation, reduce the influence of environmental temperature. QA 650, T185, T160, JAE series products can be replaced in situ, but we adopt double torque structure, it is different from other company products. We can make the accelerometer bias value and scale factor more stable; it is launch since 2010, this product has delivered thousands of products. After years of application, it has become a mature product, especially a large number of applications in the drilling measurement of oil drilling
