* The IP69K test according to DIN 40050-9 for high-pressure, high-temperature wash-down applications. 90° 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– 60° 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 30° times per minute. The sensor must not suffer any damaging effects from the high pressure water in appearance and function. 0°
