DDEN Load Cell

Description

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 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.

A version fitted with an integral amplifier is also available. Designated as the DDENA, is can incorporate any of the ICA series amplifiers to provide a conditioned voltage or current output signal, or DCell RS485 Signal Digitiser, without the need for an external amplifier, or housing.
