- Installation & Adjustment Guide Wiring Diagrams CB, M18, DC Max. Min. Sensitivity The environments in which capacitive sensors are install- ed can often be un stable re- garding temperature, humi dity , object distance and industrial (noise) interference. Because of this, Carlo Ga vazzi offers as standard features in all TRIP LESHIELD™ capacitive sensors a user-friendly sen - sitivity adjustment instead of having a fixed sensing range, extend ed sen sing range to accommodate mechanically demand ing are as, temperatu- re stability to en sure minimum need for adjusting sensitivity if temperature varies and high immunity to elec tro magnetic interference (EMI). Note: Sensors are factory set (de - fault) to maximum rated sen- sing range. Adjustment Guide Installation Hints Capacitive sensors have the unique ability to detect al- most all materials, either in li- quid or solid form. Capa ci tive sensors can detect metallic as well as non-metallic ob- jects, how ever, their traditi - onal use is for non-metallic materials such as:
- Plastic Industry Resins, regrinds or moulded products.
- Agriculture Feed, solids or grain.
- Wood Industry Saw dust, paper products, door and window frames. Materials are detected due to their dielectric constant. The bigger the size of an object, the higher the density of ma- terial, the better or easier it is to detect the object. Nominal sensing di stan ce for a capaci- tive sensor is referenced to a grounded me tal plate (ST37).
