JDB-KT-JB6 series quartz flexure accelerometer is a miniaturized, high temperature and shock resistant accelerometer. The product has excellent repeatability, start-up performance, high temperature and shock resistance and high reliability, etc. It can be used for both static and dynamic testing, and is also a standard vibration sensor.
The product adopts unique miniaturization, high-temperature and shock-resistant design, advanced packaging technology and special circuitry, the output current of the product is proportional to the input acceleration, and the user can select the appropriate sampling resistance through the calculation to achieve high-precision output. And according to the user's needs built-in temperature sensor, can be used to the bias value and scale factor compensation, to reduce the impact of ambient temperature. This product was launched since 2012, the number of deliveries reached thousands, after many years of application, it has been a mature product, especially used in a large number of oil drilling with drilling measurement.
Application areas: oil drilling inclination measurement and precision instrument and equipment vibration isolation test.
