Product Description:
The KSJB2 series quartz flexible accelerometer is an exceptionally precise sensor designed for inertial navigation in a wide range of military applications, capable of measuring forces up to 100g. This product is highly regarded for its exceptional long-term stability, repeatability, start-up performance, adaptability to various environments, and remarkable reliability.
It can be employed for both static and dynamic testing and also serves as a standard vibration and inclination sensor. The sensor's output current is directly proportional to the applied force or acceleration, and users can fine-tune it by selecting the appropriate sampling resistance. Additionally, the built-in temperature sensor allows for compensation of offset values and scale factors to minimize the effects of temperature changes as needed.
The applications of this sensor include inertial measurements in high-precision military navigation systems used in aerospace, aviation, naval operations, weapons, and various other fields, as well as precision instrument equipment vibration isolation and inclination testing.
