The sensor must not only be dust tight (IP6X), but also able to withstand high-pressure and steam cleaning. 60 The sensor is exposed to high pressure water from a spray nozzle that is fed with 80C water at 8000 10000 KPa (80100bar) and a flow rate of 146L/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 30 times per minute. The sensor must not suffer any damaging effects from the high pressure water in appea- rance and function. 0 Operation Diagram Tv = Power ON delay ON Power supply OFF Present Object (target) Not Present Tv ON Break Output (N.C.)
