In-Line Submersible Load Cell | IP68 | Underwater Force Sensor | DDEN<\/h2>\n

O-Ring Sealed, Fully Submersible, Accurate and Easily Adaptable<\/p>\n

Applied Measurements high accuracy DDEN in-line submersible load cell can be used in both tension and compression and is specially designed for applications where load or force needs to be measured underwater, or in areas subject to high humidity or the risk of flooding. The submersible in-line load cell is sealed using ‘O’ rings to provide integrity at depths up to 10 metres as standard, with greater depths possible if the appropriate modifications are made to the design. Applied Measurements standard in-line waterproof load cell model DDEN, is currently being used in various applications including wave tank measurement systems and mooring buoy cable tension monitoring. Applied Measurements DDEN an in-line submersible load cell is fitted with an ICA Series Load Cell Amplifier to provide a high-level analogue output, commonly 0-5Vdc, 0-10Vdc, ±10Vdc or 4-20mA, which is suitable for use with most data acquisition and control systems. An RS485 digital output is also possible by fitting the DCell Load Cell Digitiser in place of the ICA. To ensure high integrity underwater, Applied Measurements submersible in-line load cell sensor is constructed from Stainless Steel and has a moulded cable exit with vented polyurethane (PUR) cable (NBR, TPE and silicone seals are optional) along with an internal strain wire. Its IP68 protection rating ensures it can be used at depths of up to 10m in long term submersion in water. The vented tube linking the inside of the DDEN to the air filter positioned at the other end of the cable is there to provide an atmospheric pressure reference for the sensor to ensure that the sensor’s output is not affect when it changes and should not be removed.<\/p>\n

Rod End Bearings for Tension Use<\/h3>\n

Designed to align forces through the principle axis of the load cell thus reducing the effects of extraneous forces, hence offering improved performance from the cell. Rod End Bearings are used where tensile forces are being applied. Maintenance-free rod ends are a complete units made up of a housing with both an integral shank (with an internal or external thread) and a maintenance-free spherical plain bearing, located within the housing.
