ProTect Hygiene Sensors

Baumer proTect+ hygiene sensors

Constantly having to change the sensors in the filler room due to water ingress? Even with stainless steel sensors?

IP69k stainless steel sensors are tested by being sprayed at four different angles from a distance of 100-150mm at pressures up to 100 bars and 80°C. Test period is 30 seconds per angle. This works well if the sensor is only exposed to pressure for 30 seconds.

Baumer proTect+ Sensors

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.

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.

In order to guarantee absolute impermeability, the proTect+ sensors are subjected to extensive stress tests:
