Explanation:
SPA platform type load cell is capable of measuring weights from a single point. It offers a high level of accuracy and features an internal thermal compensation that corrects output drifts due to ambient temperature variations. It is resistant to momentum forces.
With its corrosion resistant, aluminum construction as well as its strain gauge area which is isolated with a special chemical material, SPA load cells are protected against water in accordance with IP55 standards. Suitable for platform sizes of up to 30 x 30 cm, SPA load cells are produced in various capacities (3, 6, 10, 20, 30, 35 and 50 kg) and they may be mounted in the center of or under the platform. These platform type scales with one load cell find application in conveyor scales, roller scales and process weighing applications.
