Submersible load cells!

“The DDEN series of submersible load cells was originally developed for a marine customer in Italy to measure precise mooring tension of buoys in the sea, as part of a wave energy research project. The DDENs compact design, IP68 submersible sealing and stainless steel construction made it ideal for use in this application and in numerous applications since then.” Peter Lewis Managing Director of Applied Meausurements.

"Don’t wait for better weather to do your tension and compression monitoring, use our DDEN series of submersible load cells. High humidity environments and flood risk locations are no match for this load cell."  With its IP68 fully submersible rating and robust stainless steel construction, it can accurately measure tension and compression down to 10m underwater (with greater depths available on request). The DDEN’s electrical termination is a tough IP68 multi-core cable connected through an IP68 cable gland, which further supports its fully submersible sealing.

Compact
The DDEN series of submersible load cells are unique in their compactness over their wide capacity range of 250N up to 50kN. Even at the top end of the capacity rating, the unit dimensions do not change – with a diameter of just 44mm and a length of 65mm. Along with its compact size, the DDEN submersible load cells also come with integral male threads for in-line mounting. Its compact size and in-line mounting enables the load cells to be installed in a wide variety of applications where conventional load cells such as s-beams will not fit. The image below shows our miniature ICA amplifiers fitted inside the DDEN submersible load cell. These miniature ICA amplifiers give a direct amplified output from the sensor, offering outputs in; 0-5Vdc, 0-10Vdc, 4-20mA and ±10Vdc. The DDEN submersible load cell is then sealed with ‘O’ rings to allow for permanent use underwater whilst still maintaining its compact size.

Low Deflection and High Natural Frequency/Applications
In addition, the DDEN’s low deflection and high natural frequency also makes the load cell perfect for cable tension monitoring, marine and offshore applications, mooring lines, hydrodynamic and materials testing. We are pleased to have seen the DDEN series of submersible load cells being used in a number of other applications too such as mast stays on racing yachts, which must be kept tuned to a very high level at all times.

Customisation Available
This fantastically flexible DDEN submersible load cell can be customised to suit your specific application from thread length, spherical seating rod end bearings, female adaptors, cable length, various analogue outputs such as millivolt, 4-20mA, 0-10Vdc and greater submersible depths.

Peter Lewis continues: “We can customise the DDEN series of submersible load cells for specific applications, whilst still offering the customers the same lead time as our standard range.”
