The stainless-steel housing in the design and their removable displays with backlighting are the most obvious changes to the new Element Series of digital flow transmitters. However, the redesigned housing also conceals numerous technical improvements as a result of re-engineering. These features include future-proof system architecture with a new processor and new software to optimize the performance of the sensors. The flow transmitters with 4–20-mA outputs are available in two versions: Basic (one NPN transistor output) and Advanced (two NPN/PNP transistor outputs). They comply with UL safety standards and provide long-lasting, reliable IP protection class IP 56/67. — Bürkert Fluid Control Systems, Ingelfingen, Germany
