|Would you prefer that your turbidity sensor supplier have deep experience with dairy operations?|
|Would you like to have a fast payback of your investment to help justify the cost, time and hassle of switching?|
|Is low cost a priority?|
|Are you concerned about ongoing maintenance costs and hassles?|
|Would you like to have an on-unit operator interface to monitor the sensor and ensure that it’s working properly?|
|Would you like to have both an analog and relay output for simple automation without involving a computer? (As opposed to just analog)|
|Would you prefer to only pay for the features/performance you need instead of paying extra for features you don’t need?|
|Is ease of installation and ease of use important?|
|Would you prefer a long-lived light source for the sensor (3-8 years) over a light source with a 1-year lifetime?|
|Do you think that it is important to have a sensor that stays clean? That is, the frontal sensor is EHEDG compliant and its performance is not impacted by media buildup.|
|Is it important to you that the glass optics have an extremely high reliability rating? (Sapphire versus much more fragile quartz)|
|Would you like a sensor that can tolerate interference from reflections even when used with small nominal widths or electro-polished surfaces (i.e, nominal widths from DN25)?|
|Would you like to have a full 4 to 5 ranges for your analog and switch output?|
|Is switching output (switch point and hysteresis free adjustable) important to you?|
|Is it important for your turbidity sensor to meet the CIP/SIP, etc. dairy industry process requirements?|
|Would you prefer that your turbidity sensor be color independent (wave length 860 nm)?|
|Do you need the ability for your turbidity sensor to use DN25 pipe?|
|Would you like to have a turbidity sensor that has close to 1% full scale reproducibility?|
The ITM-51 can be used in a variety of locations in your dairy as indicated in the above diagram. Below are more detailed explanations of some of the major uses of the ITM-51 turbidity sensor. General Description of the ITM-51
The ITM-51 is a turbidity sensor. It is installed on the pipeline to measure product turbidity and feeds measurement signals to a PLC or controller 4-20mA signal. The PLC provides decision based on a comparison of the incoming value versus known values for acceptable products. Turbidity sensors are far more effective than time-based systems in reducing product losses, water use and wastewater charges. Unlike time-based methods, turbidity sensors are not affected by changes you make in the system piping or the variable water supply. They eliminate the dilution of finished product commonly seen with other methods.
Phase transition is the most common application of the ITM-51 and where you will generally find your quickest payback.
Application: A turbidity sensor is located on the discharge piping prior to the final pasteurized storage tanks.
