Robust full-metal sensors for harsh environments
 |
Universal use Reliability and versatility: Can be used for level measurement and object detection. |
 |
High resistance Resistant to external factors thanks to its IP69K and high-grade stainless steel housing. Fit and forget. |
 |
By far the best Non-contact detection of even challenging objects up to a range of 2.5 metres. |
 |
Constant process overview Continuous distance measurement for maximum transparency and faster ability to act if necessary. |
Even if there is no direct contact with the medium, aggressive vapours and fumes can severely affect the function and lifespan of a sensor. The sensor surface of standard units is unprotected and therefore susceptible to contact from media such as cleaning agents, coolants or lubricants. Full-metal ultrasonic sensors consist of a stainless steel housing and are thus protected from any influences. Even the connector is made of high-grade stainless steel. Thus, the sensor is resistant to external influences and benefits from an extended service life.
The sensor is completed by an IO-Link interface, which allows other parameter and diagnostic data to be conveniently set and read out in addition to the distance value.
Added value thanks to IO-Link:
- Sound beam can be adjusted to the application
- Easy parameter setting
- Measured value transmission with millimetre precision
- Diagnostic possibilities: e.g. operating hours counter and echo quality
Ultrasonic full-metal sensors for level measurement
Cleaning challenges in food applications
- Damage due to high pressure and steam cleaning
- Cleaning agents can dissolve seals on the sensor
- The connector area is a weak point
Advantages with ultrasonic full-metal sensors
- Full-length high-grade stainless steel housing in IP 69K reliablyprotects against high-pressure and steam cleaning
- Sensor head made of durable stainless steel is resistant toaggressive cleaning agents
- Stainless steel plug resists any external influence
Challenges with chemicals, oils and gases
- Damage due to weak points on the sensor e.g. pushbuttons
- Swelling of the plastic seal due to the influence of oils –Chemicals can penetrate the unit and damage the electronics
- Plug can be damaged by e.g. disinfectants
Advantages with ultrasonic full-metal sensors
- The adjustability via IO-Link allows us to do without the “weak point pushbutton“
- Stainless steel encased sensor head protects the unit against the ingress of chemicals, other liquids or vapours
- Stainless steel plug resists any external influence
Object detection on conveyor belts
Challenges with chemicals, oils and gases
- Unreliable results due to too small detection zone or challenging object properties (structure, colour)
- Impaired functioning due to high air humidity after cleaning processes
- Unhygienic deposits on the sensor due to rough surfaces
- Damage in and on the sensor due to the effects of oils or chemicals
Advantages with ultrasonic full-metal sensors
- Large detection zone enables reliable detection of objects
- Full-length high-grade stainless steel housing in IP 69K reliably protects against:
air humidity, high pressure and steam cleaning - Ingress of chemicals or other liquids
- No deposits due to smooth stainless steel membrane
