Level sensors UP56 Pure

The non-contact ultrasonic level sensors from the UP56 Pure product family are a range of products specialized for wet chemical processes in the electronic and solar industry. Due to their PTFE-protected transducer they are very hardwearing and durable and are designed to be used in highly concentrated acids and alkalines. The UP56 Pure is easy and fast to integrate thanks to the industry-specific GF process connection. A high level of accuracy can also be achieved with fluctuating liquid densities, thus facilitating the use of dosing applications. In systems where the installation is extremely cramped, the UP56 Pure Mini is the perfect solution thanks to its very compact design. The use in containers with a lot of built-in components is easily resolved by means of an immersion pipe. The measurement range, output, and filters of the UP56 product family is easy and convenient to adjust with the PC-based programming tool Connect+.
