Features / Advantages ·· Frontflush sensor ·· Independent to reflexions at small diameters or electro-polished surfaces ·· 100 % compatible to antecessor ITM-2, mechanical and electrical ·· No color dependency (wave length 860 nm) ·· Smallest pipe diameter: DN 25 ·· Four measurement ranges, two externally switchable ·· High reproducibility: ≤ 1 % of full scale ·· Switching output (switchpoint and hysteresis free adjustable) ·· Analog output 4...20 mA (standard) Options / Accessories ·· Electrical connection with M12 plug-in connector ·· Preassembled cable for M12 plug-in connector ·· Remote version (electronics and sensor separated) 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

Specification Specification Mechanical Connetion / 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!

Installation | Advices Conditions for a measuring point according to 3-A Sanitary Standard 46-03 ■ The Sensors ITM-3 with process connection TC 1.5" und TC 2" (Tri-Clamp) are conforming to the 3-A Sanitary Standard. ■ Sensors are designed for CIP-/SIP cleaning. Maximum 140 °C / 30 min. ■ Mounting position shall be self draining and the position of the leackage hole shall be in accordance with the current 3-A Sanitary Standard. Note Adjustment ■ 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...

Showcase Diagram of different Media 110 Cream (40 % fat)* Cream (32 % fat)* Cream (10 % fat)* Full Cream Milk (3.5 % fat)* Tomato Juice Orange Juice Product Concentration in % * Average turbidity of customary milk products at different dilutions. Turbidity Diagram Depending on particle form and size, the slope of the characteristic curve is decreasing while turbidity is increasing. This is primarily caused by dampening / absorption effects due to multiple reflections inside the media. The turbidity measured in the production process can deviate from the graphs shown above, depending on product,...
