Cleaning Monitoring

A CIP cleaning process takes place in several successive steps. First, the product remaining in the plant is ejected. In the second step, organic trace elements are eliminated by means of lye and mineral deposits are removed by the use of acid. Finally, the system is rinsed with fresh water and prepared for the next production step. The liquid returning in the CIP return is monitored by a conductivity meter (e.g., SLI03). The clarification of the cleaning liquid is carried out on the basis of the measured data. But in order to detect the turbidity (impurities by residual particles) in the returning cleaning liquid, turbidity measuring devices are increasingly used. As a result, contamination can be detected early and eliminated. Especially for dairy products, the detection is very fast and efficient!

Residual Milk Mixtures

In the milk processing industry, containers and equipment are rinsed and cleaned. In this cleaning process is rinsed first with water. The residual milk flows first out of the system or containers. This is detected by a turbidity meter. This milk can be returned to the process. Depending on the content of the product components, the subsequent milk water mixture can be passed through a separator again. This measurement and decision is made via the same or a built-in turbidity meter. The measuring instruments are mounted shortly before the changeover valve and switch over without delay at the preset product concentration. Water injections are recognized immediately. The switching point is absolutely independent of quantity and time. This ensures maximum safety in the phase separation.

Contamination or product inclusions

Here a turbidity meter STS03 is installed in an ice water tank.For degassing before the measuring device was integrated into a value , which accomplished a calming of the ice water. To ensure a very fast detection, the device has been installed on the return line.
In the milk processing industry, products are heated or cooled. This is done e.g. over milk heaters or coolers . These are operated depending on the function with steam or ice water. So that a defect can be detected in the so-called heat exchanger, the circuits are provided with turbidity meters. This will immediately detect a product entry into the carrier medium and prevent further damage via the controller

LBFS(Clever Level Switch)

Media detection in chamber of pump to protect the system from dry run .
No ‘carry over’ of hazardous media Dry run protection - switches diesel generator. (considerable operational wear and fuel savings)

Application: Foam or no Foam detection in Liquid Media

The function of the LFFS is to prevent foam and other components from fermentation tanks to enter and spoil the CO2 circulation. CO2 is mostly used to push the “Liquid” (later beer) through the process and as well for the filling process of the bottles. There the CO2 is used to prevent beer getting in contact with air which would destroy the taste

Ultrasonic miniature sensors with patented coating for level measurement with aggressive media

Aggressive media such as vapors or cleaning agents are at times a challenge for standard ultrasonic sensors. The sensor face, called a transducer, can be worn by these media and thus become impaired. The new chemically robust UNAR / URAR 12 miniature sensors are a great fit for these environments thanks to an ultra-thin patented perylene coating on the sensor face and stainless steel all-metal housing. These compact sensors are an addition to the preexisting Baumer portfolio of chemically robust sensors and are available as proximity, retro-reflective and distance sensors.

O300 miniature laser sensors for the precise detection of very small objects and gaps

The new O300 miniature laser sensors with IO-Link by Baumer are the specialists for the reliable detection of very small objects and gaps. Thanks to a laser beam which focuses to within 0.1 mm and the high repeat accuracy of 0.1 mm, objects can be positioned with high precision and follow-up processes controlled exactly. Thanks to the extremely short response time of less than 0.1 ms, the sensor reliably detects even closely spaced objects, thus allowing fast processes and high throughput rates. A big advantage is the exact alignment of the laser beam to the fixing holes by design (qTarget). Thanks to qTarget, detection with pinpoint accuracy can be guaranteed over the entire series.
