Applications
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
Application fields: inclination test of bridge, dam, oil well, coal
mine, etc., high-speed railway control, ship stability control,
etc.
