ER-QA-03D High-Temp and Anti-shock Quartz Accelerometer For Oil And Gas

Features:
1. Tactical navigation grade performance;
2. Analog output;
3. Field-adjusting range;
4. Widely operating Temperature Range.

Product Details


ER-QA-03D mainly used for inclination angular test such as: bridge, dam, oil well, mining and so on, it also can be used for railway control system and ship’s stability system, which has high vibration resistant and strong shock resistant ,high and low temperature performance is superior . Especially ER-QA-03D C still has excellent performance when it in 185℃high temperature environment.
