A point level switch for hygienic applications
as well as hygienic design (3-A certified and ASME-BPE compliant), making the device reliable and nearly maintenance-free in operation. The completely welded sensor concept guarantees cleanability in the process (CIP/SIP) and thus ensures efficient operation. The point level switch can be put into operation in a few minutes without adjustment to the respective medium. The Liquiphant FTL63 switches reliably even where other measuring principles reach their limits, for example, due to changes in conductivity or dielectric constant, build-up, foam, turbulence or air bubbles. The Liquiphant technology is therefore ideal for replacing float switches, capacitive or optical sensors, and meets the current requirements for Industry 4.0. Digital capabilities Migration to Industry 4.0 requires sensors that provide relevant data to trigger process optimisation and efficiency gains. In the Technology Roadmap: ‘Process Sensors 4.0’, NAMUR calls for an additional, mobile way of communicating with the sensor. This information is used for predictive maintenance and process optimisations. Furthermore, additional product information, such as manuals or certificates, is available online on site at any time. The latest generation of the Liquiphant offers users several ways to know their process status clearly. The ultra-bright LEDs indicate switching status. The Liquiphant FTL63 also allows operators to communicate with the sensor via Bluetooth® Technology and the SmartBlue-App from Endress+Hauser. The app makes all product and diagnostic data easily available, which is particularly helpful in installation locations that are difficult to access. The diagnostic function of the Heartbeat Technology can also be accessed via the SmartBlue-App. In addition to current device diagnostics, Heartbeat Technology enables guided verification from the control room. Verification sets the foundation for predictive maintenance through frequency monitoring. By performing the verification, trends can be detected, which then provide an indication of corrosion or build-up on the sensor. When these are addressed in good time, plant shutdowns can be prevented, and plant availability increased. Verification is carried out via the SmartBlue-App directly from the control room without removing the device or interrupting the process, and is completed with an automatically generated, traceable verification protocol.
The Liquiphant level sensor has been installed more than eight million times worldwide. Developed based on a new measuring principle to meet customers’ challenges in the 1980s, it is today considered one of the most reliable and safe point level detectors in industrial plants. The latest generation of devices is ready for Industry 4.0 and the newest addition, the Liquiphant FTL63, is ideally suited for applications with hygienic requirements. At the end of the 1970s, Georg H Endress asked developers at the company for an all-metal and thus permanently sealed sensor that could switch reliably and trouble-free in any application, without needing to be adjusted for different media. It quickly became clear that the capacitive and conductive probes used until then could not meet the requirements fully. This led to the development of a new measuring principle: vibronics. Within a short time, this new technology became the best-seller from Endress+Hauser and, to this day, the vibrating metal fork is recognised as the most reliable and safe limit switch. Used for overfill or dry-run protection, the Liquiphant performs various tasks in process automation. More recently, the sensor has been equipped to incorporate the shift to digital technologies. The Liquiphant FTL51B can be used as an all-rounder for point level detection in all pumpable liquids. The Liquiphant FTL62 scores with its coatings which make it suitable for use in aggressive liquids. At high process temperatures of up to 280°C, the Liquiphant FTL64 is the preferred measuring instrument due to its special high-temperature design. The portfolio is now completed with the Liquiphant FTL63 – ideal for the food and beverage and life sciences industries due to its hygienic design. The Liquiphant FTL63 is used for point level detection in process and storage tanks, as well as in pipelines. Typical use cases include empty level detection in milk tanks, dry- run protection for pump monitoring in the cleaning system of fermentation tanks for beer production and overfill protection in the concentrate tank in fruit juice production. In all these applications, the technology works reliably in all pumpable liquids. Ideally suited for use in hygienic applications, the all- metal sensor meets the highest requirements for robustness The Liquiphant level sensor is recognised globally as one of the most reliable point level detectors for industrial plants.
