Product Highlights
The LMK858 Level Transmitter offers a versatile solution for measuring pressure in a range of 0 … 40 cmH2O up to 0 … 100 mH2O. It features a 2-wire output signal of 4 … 20 mA, with the option for other signals upon request. This level transmitter boasts several special characteristics, including its compact diameter of 45 mm, making it suitable for various applications. The cable assembly and sensor head are detachable, providing convenience during installation and maintenance.
Moreover, the LMK858 exhibits exceptional chemical resistance, thanks to its housing made of PP-HT material. It is designed with integrated lightning protection and increased overvoltage protection, offering reliable performance in challenging environments. The gas discharge tube with an 8 kA capacity (8/20 µsec) ensures robust lightning protection, while the 4 kV surge l-l/l-e protection conforms to EN61000-4-5 standards. Additionally, the LMK858 Level Transmitter offers optional versions with a 99.9% AI2O3 diaphragm, different cable types, elastomers, and the possibility of cable protection upon request.
Applications
The LMK 858 Level Transmitter is particularly well-suited for sewage applications, such as wastewater treatment, dumpsites, and water recycling facilities. In these environments, the transmitter’s robust design and high chemical resistance make it ideal for continuous level measurement in tanks, reservoirs, and open channels where sewage and contaminated water are present. Its ability to withstand the harsh and corrosive conditions typical of sewage and wastewater ensures reliable operation and long service life, even when exposed to solids, sludge, and aggressive cleaning agents.
Another key area where the LMK 858 excels is in aggressive media, including the level measurement of most acids and lyes. The transmitter’s construction from high-grade, chemically resistant plastics allows it to operate effectively in environments where conventional sensors might fail due to corrosion or material degradation. This makes it a preferred choice for chemical plants, storage tanks, and process vessels where aggressive or hazardous liquids are stored or processed, ensuring accurate and safe monitoring of fluid levels.
