ER-QA-03C Small Size Quartz Accelerometer for Aerospace
Features:
Product Details
ER-QA-03C is a smaller outline accelerometer, with high reliability, mainly used in Aviation and aerospace inertial test. Output current and the force by a linear output, the user can get high accuracy output by calculate, choose proper output load resistor. It can be used with both static and dynamic acceleration measurement. ER-QA-03C is a standard vibration sensor.
