Heavy weights moved by cranes or other lifting equipment are always a threat for the safety of persons and equipment. To answer these threats transducer and control electronics are needed to measure the related forces with high reliability. With core competencies in strain gauge and thin film technology, tecsis produces a variety of standard force transducers as well as custom specific solutions. The thin film sensors are manufactured by a combination of Plasma Enhanced Chemical Vapour Deposition (PECVD), Physical Vapour Deposition (PVD), and lithography. Due to the atomic bonding between the electrically conductive sensing layer and the substrate the sensor is very robust, and shows a good long-term stability and very little creep. Even redundant sensors can be designed in a compact form enabling the use also in applications with limited space. The company offers a diverse range of force transducers with a maximum load of up to 6 MN. Various geometries allow to integrating the transducers directly into the application. The company also addresses the challenges arisen as a result to the safety standard EN ISO 13849-1. The redundant force transducers enable applications, which fulfil performance level e according to EN ISO 13849-1. Necessary safety related steps like calculations, FEM analysis and tests are all done in-house at the company. Suitable for cranes and lifting applications, the overload monitoring system ECPS monitors crucial parameters and prevents overload situations. It consists of a central electronic unit and the respective transducers, which are integrated at different locations within the lifting equipment. Performance level c according to EN ISO 13849-1 can be achieved with the ECPS system.
