Modular Platform & IO-Link, Turbidity Sensors: ITM-51, ITM-51R

Modular, front-flush turbidity sensor for low to high turbidities, with IO-Link

NOW available with For more information click here.

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

Further Information:

  • The ITM-51 is compatible to the antecessor ITM-3.
