JA-25GA Accelerometer
Quartz Servo Accelerometers
The miniaturized 175℃ JA-25GA 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 very limited. The JA-25GA provides reliable long term operation at high temperatures without sacrificing performance required for directional drilling.
