SENSORS FOR FOOD AND BIOPHARMA. ANDERSON-NEGELE Product Information ITM-51 | ITM-51R FOOD Relative Turbidity Meter ITM-51 /CLEANadapt! Application / Specified Usage ■ Relative turbidity measurement of liquid media for mid to high turbidity range (200...300,000 NTU equivalent) 46-03 Application Examples ■ Phase separation of products (for example whey - cream - milk) ■ CIP-return line (monitoring of pre-rinse water to product leftovers) ■ Yeast harvest in breweries ■ Quality control ■ Leackage control of filter and gaskets ITM-51 Hygienic Design / Process Connection ■ By using Negele weld-in sleeves / adapters of the CLEANadapt system or the build-in system EHG-.../ 1/2" a flow optimized, hygienic and easy sterilizable installation will be achieved. ■ CIP-/SIP-cleaning up to 140 °C / maximum 120 minutes ■ Product contacting materials compliant to FDA ■ Sensor made of stainless steel ■ Optics made of high resistant sapphire ■ Process connection G1/2" hygienic, Tri-Clamp or Varivent, adapters available for milk pipe (DIN 11851), DRD, APV et al. (see CLEANadapt product information) ■ 3-A compliant Tri-Clamp process connection Features / Advantages ■ Front flush sensor ■ Independent to reflexions at small diameters or electro-polished surfaces ■ No color dependency (wave length 860 nm) ■ Smallest pipe diameter: DN 25 ■ High reproducibility: < 1% of full scale ■ Switching output (switchpoint and hysteresis freely adjustable) ■ Analog output 4...20 mA freely adjustable ■ Two ranges externally switchable ITM-51R Options / Accessories ■ Electrical connection with M12 plug-in connector ■ Preassembled cable for M12 plug-in connector ■ Display module Simple User Interface (SUI) and Large User Interface (LUI) ■ Remote version with cable length up to 30 m Measurement Principle Sensor Measuring Principle of the Relative Turbidity Meter An infrared diode irradiates infrared light into the media. Particles in the media reflecting the irradiated light which is detected by the receiver diode (backscatter principle). The electronics calculates the relative turbidity of the media according to the received signal. The relative turbidity is based on the Negele calibration standard and is displayed in ”%TU".

Specification | Advices Specification Mechanical Connection / Installation ■ The sensor has to be installed in that way that the sensor tip is entirely washed around by media and no bubbles can occure. Installation in a rising pipe is recommended. ■ If weld-in sleeve is correctly mounted the axis between the 2 connectors points in flow direction. ■ For installation in horizontal pipes from top the standard sensor with 15 mm sensor tip is recommended to avoid the influence of bubbles to the measuring signal. ■ Attention: The maximum tightening torque for mounting is 20 Nm!

·· The factory setting of the device is measuring range 1 (0...100 % = 4...20 mA). ·· With an external control voltage (24 V DC) range 2 can be selected (E1 = 24 V DC). (See “Electrical Connection”) Switching the Measurement Range flow direction ·· The digital control input E1 is galvanically isolated from the power supply. Ground: clamp 9 (0 V) E1* Measurement Range Select suitable measurement range in applications with high turbidity variances (e.g. milk / milk water mixture) for precise measurement! Device is calibrated ex works. A periodical calibration is not neccessary. A calibration...

Electrical Connection | Installation FOOD Electrical Connection ITM-51 | ITM-51R Parameterization The turbidity meter ITM-51 / ITM-51R is set to operate without requiring special settings. Should the parameters need to be changed, this can be performed using the PC-based MPI-200 programming adapter or the User Interface. For further details please refer to the operating manual. Programming adapter MPI-200-F connection Connection plug for MPI-200-F adapter as an intermediate plug between the ITM-51 electronics and the MPI-200 connection 3 (see next figure).
