The Blacknor Technology Tide and Wave Height Sensor has been used continuously throughout the world over the past 15 years in both offshore and coastal marine environments. The unit can now be supplied with a digital output, allowing easy interfacing with computer systems
Two versions are available, a Standard Unit and a Hazardous Zone 1 Unit. The Hazardous Zone 1 Unit is BASEEFA approved.
For normal operations, the Tide and Wave Height Sensor is mounted above the sea surface on a fixed platform. The unit is positioned pointing down towards the water surface. The sensor measures the distance between itself and the water surface, to provide tide and wave height data.
The sensor uses a pulsed laser to measure the distance to the nearest reflecting surface. On transmitting an infrared light pulse, the sensor measures the transit time taken for the pulse to be reflected back to the sensor. Since the velocity of the light is essentially constant and known, the measured transit time is directly proportional to the distance between the surface and the sensor. A continuous voltage in the range 0-5v representing 0 - 50 meters, is output. The value of which is proportional to the measured distance.
