Robust and user-friendly high frequency level sensor is the first available with NAMUR intrinsically safe output

The RFLS-35 sensor, from Dinel, is designed for limit level sensing of various liquids and pastes. The media can be both electrically conductive or non-conductive with any level of permittivity. It can be installed in metal or plastic tanks, filling tanks for process equipment as well as in pipes in applications such as dry run pump protection.

The sensor operates in the HF band (hundreds of MHz), allowing it to reliably detect the level even when the media leaves electrically conductive deposits, build-ups or foam (e.g. water, sewage, sludge, petroleum products, chemicals, etc.). Compared to similar HF sensors on the market, the RFLS-35 offers operators very user-friendly parameterisation using a magnetic pen and a selective "Medium Window" function, which enables media analysis and the ability to distinguish between them.

Another unique feature of this sensor is its very low current consumption - it is the first RF level sensor on the market that is also available with NAMUR intrinsically safe output. The sensor body is made entirely of stainless steel. Its sensing components are made from either PEEK or PTFE for the highest chemical resistance. Various process connections (shorter and longer with thread, Tri Clamp), various electrical connections (cable glands, connectors) and various outputs (PNP, NPN, Namur) are available.
