The Pa993D SDI-12 submersible depth sensor has a built-in 16-bit microprocessor which enables it to perform complex high-level linearisation, temperature compensation plus self-calibrations via the SDI-12 communication protocol. Plus, the integrated temperature sensor also offers built-in density correction, all of which delivers optimum stability and ensures high accuracy of less than ±0.15% full scale (0.1% optional).
As the embedded microprocessor inside the depth sensor controls the SDI-12 interface, it can accept instructions from a datalogger, perform the measurements and complex calculations, then transfers the data back to the datalogger via the SDI-12 communication protocol.
United Utilities needed a way to monitor the constantly changing water level in their water treatment plant to guarantee a steady flow of water into the reservoir. Learn how they did it using our level transmitters.
Read the real life case study of power take-off torque monitoring on the Wave Energy Converter The SeaPower Platform. See how our complete torque measuring system enabled engineers to accurately monitor the torque applied by the Wave Energy Converter as it responded to waves in the test tank with accurate, fast and reliable results.
This case study aims to significantly reduce the cost of large scale tidal turbine designs using our submersible load cells. The tidal turbine test rig was placed in a state-of-the-art test tank, where the team were able to increasing the size, flow rate and turbulence levels within the tank. Lowering the cost of rotor blade manufacture would make this renewable energy more economical to use and widely accessible, benefiting not only the UK renewable tidal energy markets but developing tidal energy countries too. Our submersible load cells measured both the torque and the thrust of the underwater tidal turbine design.
The new DBBSUB s-beam permanently submersible load cell is guaranteed to measure tension and compression in continuous submersion in potable water to depths of up to 10 metres / 1 bar. It has a glass-to-metal seal construction providing a complete hermetic sealing guaranteeing its safe performance in highly aggressive environments, whilst still maintaining its high ±0.02 % accuracy.
