Pressure (D)

The RBRsolo³ D and RBRduet³ T.D instruments (including their | deep, | fast, | tide, and | wave variants) use the piezoresistive pressure sensor. The sensor is protected by a clear plastic guard. During deployments, always orient it downwards to reduce debris collecting on the membrane of the pressure sensor.

| tide16 and | wave16 variants take averages of pressure readings over extended periods of time, providing accurate tide level data.

| wave16 instruments can also obtain wave characteristics and detect infrequent phenomena, like boat wakes.
