Instruments and Equipment
Features
●Low cost ●Broad measurement range●Low lag ●High resolution ●High stability ●High accuracy ●Low power
JB2 series quartz flexible accelerometer is a high-precision,
large-range (up to 100g) military inertial navigation grade
accelerometer product with excellent long-term stability,
repeatability, startup performance, environmental adaptability and
high reliability. It can be used for static testing as well as
dynamic testing, and it is also a standard vibration sensor.
The output current of the product has a linear relationship with
the force or acceleration received, and the user can select an
appropriate sampling resistor through calculation to achieve
high-precision output. A temperature sensor can be built-in
according to user needs, which can be used to compensate the offset
value and scale factor to reduce the influence of ambient
temperature.
Application fields: inertial measurement of military high-precision
inertial navigation systems in aerospace, aviation, ships, weapons
and other fields and vibration isolation testing of precision
instruments and equipment.
