Anderson-Negele ITM-51, ITM-51R
Relative Turbidity Meter | Food, Beverage and Dairy
Turbidity Sensors
Modular, front-flush turbidity sensor for low to high turbidities, with IO-Link.
Hygienic, front flush turbidity sensor for media with a turbidity of 200…300.000 NTU equivalent in pipes from DN25 on.
- Active phase separation in the production process: Precise differentiation of product / mixed phase / water.
- Minimisation of resource losses.
- Frontflush sensor in compact and modular design.
- Reduction of the water consumption and waste water treatment cost.
- Minimisation of the duration of a CIP-cleaning process.
- Glass-free sapphire optics.
- Flex-Hybrid: Digital IO-Link and analog 4…20 mA in parallel.
- Modular design: configurable from the low-cost basic version to the high-end model.
- Front-flush sensor: Simplified pipe cleaning (pigging possible) ideal for media with adhesive fibres or particles.
- Extended temperature and pressure range.
- Independent to reflexions at small diameters or electro-polished surfaces.
- No color dependency (wave length 860 nm).
- High reproducibility and fast response time.
- Selectable output value (%TU, NTU, EBC).
- Extended measurement range: 200…300.000 NTU equivalent.
Application examples
- Phase separation products (whey-cream-milk).
- Separator control.
- CIP-return line (monitoring of pre-rinse water to product leftovers).
- Automation of the yeast harvest and the separator monitoring in breweries.
- Quality control.
- Leakage control of filters, gasket, valves.
Benefits in the production process
ITM-51 enables active automated phase separation instead of passive time or volume control. That saves time and cost in the transition of milk / water resp. of beer / yeast, on the base of inline analysis of the turbidity and active switching of the process.
- Minimization of resource loss and thus loss of value.
- The filling of tanks with wrong medium is avoided.
- Less cost for waste water treatment.
- Less need for additional laboratory analyses.
- Best possible concentration and constantly high quality.
- of the product such as milk / cream resp. beer / wort.
- Efficient separator control in breweries for uniform.
- quality of infiltered beer.
Benefits in the CIP-SIP-Process
Active automated and temperature-independent phase separation in the return of product / acid / caustic / water.
- Reliable control of the degree of pollution of the agents.
- Optimal multiple use of the cleaning agents.
- Cost minimizing due to less waste disposal.
- Reduction of the cleaning process time and thus also of the water consumption: active switching after reaching the desired degree of purity by inline turbidity analysis, and not after passive, fixed timing.
Practical experience / Applications
- Reduction of product loss from 5% to 3%, and 15% cost reduction due to less waste water treatment.
- Less laboratory analyses necessary, thus less personnel / time requirement and faster reaction to deviations.
- 3.000 l less water consumption in each CIP process.
- ITM-51 prevents reliably the contamination of a glycol cooler with milk products, a fact which before repeatedly disturbed the cooling process and caused a complete cleaning.
- 80% more consistency in the quality of the end product due to more precise separation of cream, mild and low-fat milk.
- Constant turbidity level for Craft Beer without filtering thanks to precise separator control in a brewery.
