JDSJ18TK01
Miniaturized, high-precision, large-range inertial tactical & navigation-grade accelerometer with excellent stability, repeatability, and reliability
Customizable Parameters
Specifications shown are reference configurations. Most parameters can be adjusted to meet your application requirements.
The JDSJ18TK01 series quartz flexure accelerometer is a miniaturized, high-precision, large-range inertial navigation-grade accelerometer known for its excellent long-term stability, repeatability, startup performance, environmental adaptability, and high reliability. It is suitable for both static and dynamic testing and also functions as a standard vibration and tilt sensor. The product features a unique miniaturized design and packaging process, with output current linearly related to the applied force or acceleration. Users can calculate and select appropriate sampling resistors to achieve high-precision output. Additionally, a temperature sensor can be integrated upon user request to compensate for bias and scale factor, reducing the impact of environmental temperature variations.
