Description

Applied Measurements DBB Z-beam load cell / S-beam load cell is suitable for use in tension or compression with IP67 immersion protection to 1m.  The design lends itself to both force and load measurement applications such as those found on tensile testing machines, suspended hoppers and geotechnical test equipment, as well as a wide range of other general-purpose applications.

The sensing principle employed on our Z-Beam load cell varies, with a dual bending beam design on the DBBE model which covers capacities from 50kg up to 1000kg and a shear web design on the DBBWAS model which cover ranges from 0-1500kg to 0-6000kg.  Both sensing principles offer inherently high accuracy and enable us to guarantee performance of better than ±0.03% of rated capacity.

All our DBB models are constructed from nickel-plated alloy steel.

Rod end bearings and load buttons are available (see gallery images) to provide optimum loading conditions.

*The resonant frequency is calculated with the body of the load cell attached to a large plate, ensuring that only the sensing element oscillates: This is vital to achieve the highest natural frequency and subsequent frequency response.
