KTOE-JB3 series quartz flexure accelerometer is a miniaturized, high-precision, large-range inertial accelerometer with excellent long-term stability, repeatability, start-up performance, environmental adaptability and high reliability, which can be used for both static and dynamic testing, and is also a standard vibration sensor and inclination sensor. The product adopts a unique miniaturized design and packaging process, the output current and the force or acceleration are linearly related, the user can calculate the selection of the appropriate sampling resistance, to achieve high-precision output. According to the user's needs, the built-in temperature sensor can be used to compensate the bias value and scale factor to reduce the influence of ambient temperature.
Application areas: inertial measurement of inertial guidance system in aerospace, aviation, shipbuilding and other fields, and vibration isolation test and inclination test of precision instruments and equipments.
