Because of this, Carlo Ga­ vazzi offers as standard features in all TRIP­LESHIELD™ capacitive sensors a user-friendly sensitivity adjustment instead of having a fixed sensing range, extend­ ed sen­ sing 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).

Sensitivity Installation Hints Capacitive sensors have the unique ability to detect al­ most all materials, either in li­ quid or solid form. Capa­ci­tive sensors can detect metallic as well as non-metallic ob­ jects, how­ ever, their traditional use is for non-metallic materials such as: • Plastic 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 • Chemical Industry Cleansers, fertilisers, liquid soaps, corrosives and petrochemicals. • Wood Industry Saw dust, paper products, door and window frames. • Ceramic & Glass ­Industry Raw material, clay or finish­ ed products, bottles. Relief of cable strain • Packaging Industry Package inspection for level or contents, dry goods, fruits and vegetables, dairy products. 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. Nominal sensing di­ stan­ ce for a capacitive sensor is referenced to a grounded me­ tal plate (ST37).
