Impermeable proTect+

Baumer sensors were developed to guarantee outstanding impermeability over their entire service life. While sensors in other impermeability tests are only tested for their water impermeability when new, the proTect+ testing process first simulates the effects of aging on the sensors. After aging, the sensors are subjected to impermeability tests in accordance with the specific IP protection class guidelines in order to guarantee impermeability.

What is proTect+?

proTect+ is an impermeability concept developed by Baumer which ensures the long-term functionality of the sensor even under the most demanding conditions. In order to guarantee the special impermeability of the sensors, great importance is attached to the selection of the right materials as well as the optimisation of the design during development. Extensive stress tests according to the proTect+ guidelines then check the long-term impermeability of the sensors. 
 
First, the test sensors are subjected to either water temperature or air temperature shock tests to simulate aging effects and thus the life cycle of a sensor in the machine. Each sensor has to go through a total of 50 temperature cycles.  Then the tests in accordance with the IP68 and IP69 K protection classes are implemented.

Selected materials:

Materials such as V4A/V2A stainless steel, chemically nickel-plated heat-treated steel, NBR, liquid silicone rubber, polyamide and others are used to ensure special impermeability in accordance with proTect+. In addition, smooth and impermeable surfaces prevent dirt and bacteria from adhering to sensors with the hygienic design, allowing simple and thorough cleaning of the sensor.

Optimized design:

Mechanical interfaces are designed in a way that even at critical points, such as cable outlets or LED switching status indicators, absolute impermeability is ensured even with foam or high-pressure cleaning.

proTect+ test series

In order to guarantee absolute impermeability, the sensors are subjected to extensive stress tests. The following test procedures are performed:

Applications

Sensors with proTect+ are particularly suitable for harsh industrial environments, most notably in outdoor, hygienic and washdown applications where the sensors are exposed to repeated cleaning cycles and aggressive chemicals. Once you use them, these sensors will quickly convince you of their reliability and impermeability in challenging applications.
