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.

*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.

Mounting and Installation Accessories

Load Buttons and Rod End Bearings

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.

Load buttons are used where compressive forces are applied.
Rod End Bearings are used where tensile forces are being applied.

Case Studies

Force Measurement Determines The Effect of Girth Tension on Horse Gait

Equine Tension Load Cell

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.
