The 200 kHz EchoRange Smart Sensor is an ultrasonic underwater temperature and depth sensor that transfers its gathered NMEA 0183 data in real time to a computer via the RS422 standard. With embedded transceivers, sophisticated digital signal processing, and user-configurable depth range and ping rate resolution, it is ideal for applications such as inspection and hydrographic surveying.

The 200 kHz EchoRange+ Smart Sensor adds a bi-directional NMEA 0183 interface to the above sensor, and includes an OEM-exclusive Echo Envelope Developer Option. This provides a secondary transmit-only interface with a proprietary protocol using RS485, and allows users to obtain detailed echo envelope data which can be displayed as an analog waveform. Analysis of this data provides information about the seafloor type.
