Level Measurement CN7000

  1. Capanivo in tomato paste / Capanivo trong bột cà chua:

One of the leading Peruvian food companies needed to measure tomato paste at 100ºC. After the material became paste and has lost almost all of the liquid it reaches a very low dielectric value, however very sticky. Another concern is the chemical resistance to the hig temperature CIP process, about 90ºC, together with the Food Grade compatibility. The solution should be highly reliable and the probe compact because tank dimensions and process dynamics could occur in overflows. Also the accuracy in detection is a critical point as the material tended to generate false alarms.

 Our Solution

For this case we applied our Capanivo 7000 series level switch sensor, which has process connection made of stainless steel and PPS probe (Polyphenylene Sulfide), a hygienic plastic, chemically compatible with aggressive applications for the cleaning process. The probe is only 98mm long, so it is suitable for installation in very small spaces. In addition, the IP68 housing is made of polyester and polycarbonate, thus environmentally resistant and properly sealed. An important highlight is that this sensor works with two wire electronics and has “Tip sensitivity” technology providing high accuracy in the detection adjustment, even with the very sticky tomato paste our solution could manage to provide the right signal output

2. Capanivo with sulphuric acid in a pipe 

A renowned manufacturer of aluminium sulphate has tanks of sulfuric acid of 98% as raw material for its production. They needed to detect the low level in a pipe with a reduced diameter of ca. 200mm. Due to the material with high corrosion the chemical resistance was important by selecting the process material and the probe should be quite short. Also, they were looking for a solution with 1 “BSP process connection, as a pipe changes would be difficult.

          ⇒ Our Solution

For this case we applied our Capanivo 7000 series level switch sensor, which has a 1″ process connection and PPS probe, a high performance plastic, chemically reistant to aggressive applications such as sulfuric acid. The probe is only 98mm, so it is suitable for installation in very small spaces. In addition, the IP68 housing is made of polyester and polycarbonate, thus environmentally resistant and properly sealed. An important highlight is that this sensor works with two wire electronics and has a “Tip sensitivity” technology providing high accuracy in the detection adjustment.
