JDSJ25TK02
High-precision, high-range inertial navigation-grade accelerometer featuring excellent stability, repeatability, and reliability for applications up to 100g
Customizable Parameters
Specifications shown are reference configurations. Most parameters can be adjusted to meet your application requirements.
The JDSJ25TK02 series quartz flexure accelerometer is a high-precision, high-range inertial navigation-grade accelerometer (up to 100g). It boasts excellent long-term stability, repeatability, startup performance, environmental adaptability, and high reliability. Suitable for both static and dynamic testing, it also functions as a standard vibration and tilt sensor. The accelerometer’s output current maintains a linear relationship with the applied force or acceleration, allowing users to select appropriate sampling resistors to achieve high-precision outputs. Additionally, an internal temperature sensor can be integrated upon request to compensate for bias and scale factor variations, thereby minimizing environmental temperature influences.
