Save instead of fishing in murky water: turbidity sensor ITM-51 from Anderson-Negele

Inaccurate phase separation in the food production industry leads to product losses, which quickly become expensive. These losses can be significantly reduced by switching at the right moment. With the ITM-51 turbidity meter from Anderson-Negele, phase separation is pinpoint accurate.

With each imprecise phase separation between different media, such as milk, cream, yoghurt or water, a certain amount of the product is lost. In addition to the loss of the value of the goods, costs for wastewater treatment and energy costs are generated. Experience shows that a medium-sized dairy or brewery could save several hundred francs a day with optimal use of the raw material.

Active or passive phase separation

Phase separation can be carried out actively or passively. In passive separation, switching is carried out without recording and assessing the medium on the basis of time and volume calculations. A safety buffer must therefore be included, which always leads to loss of product. Active regulation of phase separation is based on analysis of the medium during the process. It registers the change, makes the changing media distinguishable and precisely triggers the switching as soon as the predefined values are reached.

Minimal product loss by measuring in the medium

Turbidity and conductivity sensors play the key roles in regulating phase separation. The more precisely these sensors work, the lower the loss of product. Bachofen offers high-quality measuring technology for both processes and is setting a new standard in turbidity measurement with the Anderson-Negele ITM-51 turbidity sensor. The device is designed for applications with medium to high turbidity values. The sensor is extremely versatile, with a high temperature range between 130°C for continuous operation and 140°C for 120 minutes.

Short response time, high reproducibility and maintenance-free LED technology

The ITM-51 boasts a short reaction time of 0.75 seconds and high reproducibility. The innovative turbidity sensor works according to the backscatter principle, meaning infrared light is shone into the medium, reflected by the particles present in the medium and detected by the receiver diode. The measurement result is not affected by either the colour of the medium or the reflection created in small pipe diameters (from NPS 25). The wear-free LED technology ensures a long service life, even when operating in high temperature ranges. Users have the freedom to choose between the %TU unit for milk products, the NTU turbidity unit (phase separation), EBC (breweries), and %solids (definable solids content for wastewater monitoring).

The savings potential with active regulation of the phase separation using the ITM-51 turbidity sensor is enormous. Using a calculation tool developed by Anderson-Negele, Bachofen can show how enormous it is using individual data for each case. Free of charge and non-binding. Fact-based advice pays off.
