Product Description:
KSJB4 series quartz flexible accelerometer is a high-temperature
and vibration-resistant sensor, recognized for its excellent
repeatability, start-up performance, high-temperature resilience,
and reliability. It is suitable for static and dynamic testing and
functions as a standard vibration sensor.
The product is characterized by its innovative high-temperature and
seismic design, advanced packaging technology, and a specialized
circuit. Its output current is directly proportional to the
measured acceleration, making it suitable for static and dynamic
acceleration measurements. Users can achieve high precision output
by selecting the appropriate sampling resistance. Additionally, it
can be equipped with a temperature sensor to compensate for offset
and scale factor based on user requirements, effectively mitigating
the influence of ambient temperature. Notably, this product is a
versatile replacement for QA650, T185, T160, and JAE series
products, featuring a unique double torque structure that
distinguishes it from competitors. This innovation enhances the
stability of accelerometer offset values and scale factors while
holding independent intellectual property rights. Since its
introduction in 2010, this product has seen thousands of deliveries
and has matured over years of application, particularly excelling
in the measurement while drilling processes in the oil industry.
Application fields: bridge, dam, oil well, coal mine inclination
test, high-speed railway control, ship stability control.
