JA-35H165/H185 Accelerometers
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.
