Furthermore, these sensors feature increased immunity to electromagnetic interference (EMI), especially to frequency drives. Not only does 4TH Generation TRIPLESHIELDTM feature an increased EMI, but it also increases the immunity to humidity and dust. The implementation of stability indication eases the setup procedure as both Stable ON and Stable OFF positions are Ordering Key indicated by the green and yellow LEDs. The sensing distance is increased by 25 % allowing room for additional stable detection. The Dust Alarm function gives an early warning that the sensing surroundings have to be cleaned. The Temperature alarm function raises an alarm if the sensing surface goes beyond 60 degree Celcius. The sensor housing is featuring IP69K as well as approval by ECOLAB for cleaningand disinfection agents.

The sensor must not only be dust tight (IP6X), but also able to withstand high-pressure and steam cleaning. The sensor is exposed to high pressure water from a spray nozzle that is fed with 80°C water at 8’000– 10’000 KPa (80–100bar) and a flow rate of 14–6L/min. The nozzle is held 100 –150 mm from the sensor at angles of 0°, 30°, 60° and 90° for 30s each. The test device sits on a turntable that rotates with a speed of 5 times per minute. The sensor must not suffer any damaging effects from the high pressure water in appearance and function. 90° 60° 30° 0° 2 Specifications are subject to change without notice (10.12.2020) CA18CAN/CAF..... Adjustment Guide The environments in which capacitive sensors are installed can often be unstable as regards temperature, humidity, object distance and industrial (noise) interference. That is why Carlo Gavazzi offers as standard features in all TRIPLESHIELDTM capacitive sensors a user-friendly sensitivity adjustment instead of a fixed sensing range. Likewise, these sensors provide an extended sensing range to accommodate mechanically demanding areas and tem- Note: The sensors are factory set (default) to nominal sensing range Sn.Sn. perature stability to ensure high immunity to electromagnetic interference (EMI) and a minimum need for adjusting sensitivity, if the temperature varies.

Installation Hints Capacitive sensors have a unique ability to detect al­ most any material in li­quid or solid form. Capa­ ci­ tive sensors are able to detect me­ tallic as well as non-metallic ob­jects. How­ever, their traditional use is for non-metallic materials such as: • Plastics Industry Resins, regrinds or mould­ ed 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, fertilizers, liquid soaps, corrosives and pe­­­t­­ro­­­chemicals. • Wood Industry Saw dust, paper products, door and window frames. • Ceramics & Glass ­Industry Raw materials, clay or finish­ed 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 ma­ terial, the better or easier it is to detect the object. Protection of the sensing face The nominal sensing di­stan­ ce for a capacitive sensor is refe­­r­red to a grounded me­tal plate (ST37).
