Profile: Ocean Sensor Systems, Inc. is a manufacturer of submersible wave gauges and controllers for the engineering and environmental community. Our product line includes wave staffs, wave loggers, RF wave loggers and other accessories. Our The OSSI-010-002E Wave Staff is a water level sensor that combines a rugged, sealed, waterproof package, low power microprocessor and a temperature stable, sensing circuit. The wave staff operates from 5.5V to 40VDC and has analog, RS232 serial data & 2 alarms outputs. The serial data output string contains the water level & temperatures in ASCII or binary format. The alarm outputs are 350mA open drain type with 60V inductive load clamps. The wave staff can be programmed to free run or sample on demand. Our OSSI-012-012 and OSSI-012-012C are designed to take synchronous samples from 2 to 6 wave staffs and combine the results to a single RS232 data stream at 38.4K baud. There is no need to pre-configure the wave staffs as they are automatically configured by the synchronizers at power up time.
