185℃ Woring Temp Quartz Accelerometer Earthquake Resistant Accelerometer With Excellent Repeatability
Product Introduction
JB4 series quartz flexible accelerometer is a kind of high temperature and earthquake resistant accelerometer, the product has excellent repeatability, startup performance, high temperature and earthquake resistance performance and high reliability, can be used for static test or dynamic test, is also a standard vibration sensor.
The product adopts unique high temperature resistance and seismic design, packaging technology and special circuit. The output current of the product is proportional to the measured acceleration, and the measurement of static and dynamic acceleration is provided. Users can select the appropriate sampling resistance through calculation to achieve high precision output, and the built-in temperature sensor can be used to compensate the offset value and scale factor according to user needs. Reduce the impact of ambient temperature.
Application: bridge, dam, oil well, coal mine dip test, high-speed railway control, ship stability control.
