M20 Vector Sensors
The M20 family of accelerometer-based vector sensors offers accurate and high-sensitivity measurement of particle motion down to very low frequencies in either 2D or 3D. They can be deployed in a variety of conditions, from within 1 m of an air gun to quiet ocean environments.
The sensors are ideal for a wide variety of applications requiring direct measurement of particle motion including environmental monitoring, marine mammal detection, and offshore oil and gas and energy platform monitoring. They can also be used as low-frequency directional hydrophones.
