JDB-KT-JB100 3-axis integrated quartz flexure accelerometer is a highly integrated, high precision inertial quartz flexure accelerometer with excellent long term stability, repeatability, start-up performance, high reliability and high integration. The product can be used for both static and dynamic testing, and is also a standard vibration sensor.
The product uses a specially designed dedicated circuit, the output current is proportional to the acceleration input, providing static and dynamic acceleration measurement. The appropriate sampling resistance can be selected by calculation to achieve high precision output, and a temperature sensor can be built-in according to user requirements, which can be used by the user to compensate the bias value and scale factor to reduce the effect of temperature.
Application areas: inertial measurement of high-precision inertial guidance systems in aerospace, aviation, marine and other fields and precision instruments and equipment.
