Quartz Servo Accelerometers
The JA-35 series accelerometers are developed to be the smallest servo balanced quartz pendulum accelerometer in the world, meeting the increasing space limitations in tool designs for downhole applications. The JA-35 series accelerometers enables design engineers to develop sub inch diameter probes including directional modules or inclinometers.
- 185 or 165 °C operating temperature
- Smallest quartz pendulm accelerometer for downhole applications
- Ultimate reliability
ApplicationsDesigned for extreme downhole applications including :
- Directional Drilling
- At bit inclination
