Miniature Low Profile Submersible Tension & Compression LOAD CELL DDEN Series

Product catalog summary

Description
The DDEN series of submersible low profile load cells is designed for measuring tensile or compressive forces in underwater environments or areas with high humidity or occasional flooding. Its compact design allows for in-line mounting in applications where conventional load cells do not fit. The DDEN offers low deflection and high natural frequency, making it suitable for material testing and cable tension monitoring. It can be supplied with monitoring/control electronics and calibrated as a system. The DDENA version includes an integral amplifier for conditioned voltage or current output.

Miniature Low Profile Submersible Tension & Compression LOAD CELL Low Profile and Very Compact Integral Male Threads for In-Line High Natural Frequency Robust Construction Options Available Non-Standard capacities & sizes on request Integral ICA Series Signal Conditioning Amplifier: Shunt Calibration Facility Spherical Seating Rod End Bearings Female Adaptors available on request Compression Fittings available on request The DDEN range of submersible low profile load cells is designed for the measurement of tensile or compressive forces in underwater locations and in situations where very high humidity or occasional submersion due to flooding is likely. The DDEN's compact design proves to be advantageous by enabling in-line mounting of the load cell in a wide variety of applications where conventional load cells such as S-Beams will not fit. The low deflection and high natural frequency of the DDEN offers particular benefits in material testing and cable tension monitoring applications. The DDEN, as with all other Applied Measurements sensors, can be supplied complete with monitoring/control electronics and calibrated as a system (please refer to the instrumentation datasheets). Aversion fitted with an integral amplifier is also available. Designated as the DDENA, it can incorporate any of the ICA series amplifiers to provide a conditioned voltage or current output signal such as 0.1 -1 OVdc or 4-20mA. Transducer Specialists.
