Product Quality and Standards

Load cells are electro-mechanical transducers that translate force or weight into voltage. This change in voltage produces, in the read-out instrumentation, a repeatable deflection or indication that can be calibrated directly in terms of the load applied to the cell.

Construction of the load cell utilizes all the advantages of bonded foil strain gages. Sealed within the load cell are sets of matched strain gages bonded to a high strength element, machined to close tolerances. The strain gages are electrically connected to form a balanced Wheatstone bridge and additional compensation resistors are added to the circuit for maintaining the accuracy of the bridge over a wide temperature range. The principle of operation depends upon the deflection of the strain gage filament, creating a change in its resistance, thereby unbalancing the bridge circuit. As a result, for a given input voltage, the output voltage of the bridge varies proportionally with the load and the change can be read on appropriate instrumentation. When completed, each load cell is individually tested and calibrated. Each cell must meet or exceed rigid electrical and mechanical performance tests before it is released for service. Also, every cell is proof tested to its full rated capacity, and in most instances, to over its rated capacity.

The Loadstrain has a range of tension link load cells that are locally designed and manufactured.

They can be used in crane weighing, tension measuring and cable testing to name but a few uses. The units are portable, come in their own carry cases and are weatherproof.

How often do load cells need to be calibrated? ›

How often should a load cell be recalibrated? As strain gauge load cells are exposed to continuous usage, aging, output drift, overload and improper handling, FUTEK highly recommends a yearly recalibration interval.

How accurate is load cell calibration? ›

Load Cell Calibration is an adjustment or set of corrections that are performed on a load cell, or instrument (amplifier), to make sure that the sensor operates as accurately, or error-free, as possible. An offset means that the sensor output at zero load (true zero) is higher or lower than the ideal output.

Do load cells need to be calibrated? ›

It is typically required that load cells be recalibrated every year, ideally using the same digital indicator and other components included in the system application. Load cells that experience continuous use or are used in harsh environments will likely require more frequent calibration.
