Because of this, Carlo Gavazzi offers as standard features in all TRIPLESHIELD™ capacitive sensors a user-friendly sensitivity adjustment instead of having a fixed sensing range, extended sensing range to accommodate mechanically demanding areas, temperature stability to ensure minimum need for adjusting sensitivity if temperature varies and high immunity to electromagnetic interference (EMI). Note: Sensors are factory set (default) to nominal sensing range Sn. • Chemical Industry Cleansers, fertilisers, liquid soaps, corrosives and petrochemicals. • Packaging Industry Package inspection for level or contents, dry goods, fruits and vegetables, dairy products. tive sensor is referenced to a grounded metal plate (ST37). For additional information regarding dielectric ratings of materials please refer to Technical Information. Installation Hints Capacitive sensors have the unique ability to detect almost all materials, either in liquid or solid form. Capacitive sensors can detect metallic as well as non-metallic objects, however, their traditional use is for non-metallic materials such as: • Plastics Industry Resins, regrinds or moulded products. To avoid interference from inductive voltage/ current peaks, separate the prox. switch power cables from any other power cables, e.g. motor, contactor or solenoid cables • Wood Industry Saw dust, paper products, door and window frames. • Ceramic & Glass Industry Raw material, clay or finished products, bottles. Relief of cable strain Materials are detected due to their dielectric constant. The bigger the size of an object, the higher the density of material, the better or easier it is to detect the object.
