Description
Applied Measurements DBB Z-beam load cell / S-beam load cell is suitable for use in tension or compression. 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.
If you require a Z-Beam load cell with capacities of less than 50kg or greater than 6,000kg, Applied Measurements DBBSM series of S-Beam load cells covers load ranges from 0-1kg (10N) up to 0-30,000kg (300kN). Meanwhile, if you need to fit into a restricted space, our DBBSMM range of miniature S-Beam load cells will fit the bill.

Case Studies
Force Measurement Determines The Effect of Girth Tension on Horse Gait
Using electrical systems for the measurement of mechanical forces is by no means limited to machines and laboratory based applications. In her recently completed research thesis ‘Girth Tensions and their Effects on Equine Stride Characteristics’, Sue Wright of Moulton College Northampton used load cells, motion sensors and GPS amongst other technologies to measure and record the tension within the girth strap used to hold the saddle in place.
