JA-25H200 Accelerometer

Quartz Servo Accelerometers

JA-25H200

The miniaturized 200°C JA-25H200 servo balanced quartz pendulum accelerometers can be integrated within one inch diameter probes for downhole applications. The miniature size enables design engineers to develop more ruggedized drilling tools where mechanical space is limited. The JA-25H200 provides reliable long term operation at extreme temperatures without sacrificing performance required for directional drilling.
