Pressure Sensors Read From The Top

Monitoring the pressure of tides, water levels, and waves in ports, coastal and inland waters, rivers, and boreholes, the company’s vented pressure sensors measure hydrostatic pressure caused by the head of water above them. The influence of barometric pressure on the sensors is compensated for by applying air pressure to one side of the transducer through an air pipe and compensating unit. In addition to the sensing element, the sensors contain a temperature-compensating and range-reducing network. Pressure measurements are sampled and temperature compensated by a digital-signal processor (DSP) and the sensor application areas are in fixed installations, either deployed in a seabed installation in shallow waters or mounted onto a fixed structure in the upper water column. The sensor series includes the vented pressure models 4425, 4426, and 4427, vented tide 4445 and 4446 sensors, and the vented wave 4428 and 4429. For more details and specs, visit
