Welcome To The Cutting Edge In Calibration Technology

Meeting the challenges of modern industry and the requirements of international quality standards are core to the Loadstrain Calibration philosophy. We design, manufacture and supply load cells of the highest quality, enabling our customers to carry out measurements to traceable standards. We are committed to sustained growth through continued investment in product development and manufacturing methods.

The Loadstrain Calibration Service Offering is tailored around rigorous manufacturing and test procedures to ensure total quality and unrivalled reliability in the supply, repair and hire of our product range.

In today’s competitive manufacturing environment, it is essential that measuring equipment and reference standards satisfy the requirements of quality system accreditation. To this end, our laboratory testing is conducted in accordance with the procedures, practices and conditions required, recommended by SANAS and/or its affiliated partners, agencies and organizations.
Loadstrain Calibration have a proprietary range of locally manufactured tension link load cells ranging from 1 – 200 tons.


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. The technical specifications include a greater than 0.3% accuracy level, remote output, auto zeroing, overload indicator, a high overload coefficient and most importantly, a safety factor of 6 : 1.

Standards, equipment, and associated apparatus are suitable for the correct performance of calibrations and tests and are maintained in accordance with the requirements of ISO 17025.
The Loadstrain Load cells are manufactured from exotic steel and offer great stability, along with all the inherent advantages of strain gauge devices such as accuracy, reliability, and resolution.
